TRADE FACILITATION AND THE PERFORMANCE OF INDONESIAN MANUFACTURING EXPORT

This paper analyzes the impact of trade facilitation on Indonesian manufacturing export performance. Some specific data of Indonesia and thirty countries as Indonesian main trading partners of manufacture commodities over the period 2010 to 2014 were used to construct trade facilitation indicators, including measures in the customs and regulatory environment, port efficiency, and service sector infrastructure. The relationship between Indonesian export performance and these indicators were estimated using a gravity model with panel data. The findings provide some evidence that trade facilitation on customs environment of Indonesia and its trading partners largely and positively affects Indonesian manufacturing export performance, while the Indonesian regulatory environment deters the trade flows. Trade partnerships with ASEAN countries positively and significantly affect Indonesian manufacturing export performance. It is suggested for policy implication to prioritise efforts and development on Indonesian customs environment and its trading partners, through time and cost efficiency to trade. Moreover, Indonesia should generate more trade within ASEAN region which could stimulate a higher export performance.


INTRODUCTION
The global trade has now become increasingly liberalised as countries in the world become more integrated through international trade agreements, and also due to unilateral reforms.While agreement and policy reforms may eliminate barriers to trade, not all costs in trade are diminished through the liberalised market (Hoekman & Nicita, 2010).In fact, traders still face inefficiency in time and high trade-related costs due to excessive bureaucratic regulation and poor infrastructure.The results of a World Bank survey 'Ease of Doing Business' in 2008 revealed that administrative barriers, known as 'red tape' bureaucratic procedures related to the shipment of trading goods in developing countries, are estimated to cost more than 10 percent of the export value.The study of Marquez-Ramos et al. (2011) found that institutional trade barriers significantly affect trade flows than tariff barriers.In addition, congestion problems and the bottleneck in movement of goods in ports due to poor infrastructure have significantly contributed to high transportation costs, especially in the Southeast Asian countries (Abe & Wilson, 2009).
Efficiency is a key determinant for every country in order to compete in the global economy, as it can drive export competitiveness.To improve a country's efficiency, governments should facilitate trade by easing the flows of goods and lowering the costs.In other words, it is important to take into account the trade facilitation on the development agendas.
While there is no standard definition for trade facilitation, in a general sense, trade facilitation can be interpreted as a policy to eliminate international trade costs (besides tariff and non-tariff barriers) such as administrative delays, transaction and institutional costs, transportation costs and any other costs, which are not explicitly stated in a country's official framework, known as 'non-official barriers' (Zaki, 2008).
Trade facilitation has become a global concern in the last decade, so the importance of reform and development in this area is considered to be significant with regard to increase the efficiency and competitiveness of a country.Many empirical studies have investigated the impact of trade facilitation on trade flows; however, studies in the case of a specific country are still limited.The objective of this study is to examine the impact of trade facilitation on the performance of Indonesian manufacture's export to its main trading partners.This examination provides some insights for policy makers in terms of prioritising development and reforms in trade facilitation in Indonesia to achieve higher export performance.
Indonesia has taken various trade facilitation measures to simplify and harmonise trade-related procedures as well as to develop supporting infrastructure in line with ongoing agreements at the multilateral and regional levels, such as the Trade Facilitation Agreement organised by the World Trade Organisation (WTO) and the ASEAN Trade in Goods Agreement (ATIGA) held by the Association of Southeast Asian Nations (ASEAN).
By being actively involved in several economic cooperations, Indonesia's objective is not only aimed at opening market access and reducing trade barriers for Indonesian exports, but also at engaging with the global trade system (Damuri, 2006).
To measure the efforts of trade facilitation reforms in line with various agreements, it requires indicators that reflect the broad conditions of Indonesian trade facilitation.In this respect, constructing and combining indicators from different sources is expected to provide specific measures that also meet the needs of policymakers.Figure 1 depicts the six indicators used to measure trade facilitation in Indonesia over the last five years, following the indicators used in Wilson et al. (2003Wilson et al. ( , 2005)).The documents, time and costs involved in conducting export and import with Indonesia's 10 main trading partners are shown in Table 2. Singapore showed the top performance with less documents, time and cost required to conduct the international trade compared to other countries.In contrast, Japan was the lowest performing among the 10 countries based on the Doing Business (DB) rank in 2015.

Indonesian Export Performance
Reforms and development of trade facilitation is expected to enhance Indonesian competitiveness and generate more trade flows into and from the country.In fact, since the end of the oil boom in the mid 1980s Indonesia has modified its trade policy from import substitution industrialisation to become more export-oriented.This export-led growth strategy has been the driver of Indonesian economic movement, and as a result of trade reform and liberalisation taken in the 1980s, the value of exports has grown until both export and import values decreased in 2009, they reached a new peak in 2011 (as evidenced in Figure 3).However, since 2012 Indonesia merchandise trade has experienced a trade deficit.This is mainly due to a trade deficit in the oil and gas sector as a consequence of the high demand for fuel subsidies.The price fall in Indonesia's major commodities in the international markets had lowered export values and imposed regulations banning export of unprocessed minerals in early 2014 (World Bank, 2015a).In terms of export commodities, Indonesia's export merchandise is still dominated by fuels and mining products, followed by manufactured goods, and agricultural products with the proportion of total exports at 38.3%, 37%, and 23.3% respectively (World Trade Organization, 2014).Government regulations banning export of raw materials is aimed at increasing the value adding in Indonesian mine and mineral commodities.By exporting the processed commodity, it is expected to stimulate higher performance of manufacturing export while the contribution of raw material export is limited.Therefore, it is esential to observe the impact of trade facilitation on manufacturing export performances, in order to prioritise reforms and development of Indonesian trade facilitation measures.The percentage share of Indonesia's manufacturing export market is dominated by developed countries such as the USA, Singapore and Japan at 13.89%, 12%, and 11.33%, respectively.While markets in ASEAN countries are also considerably high, Figure 4 shows that in 2014 Singapore, Malaysia, Thailand, Philippines and Vietnam were among the top 20 destination countries for Indonesian manufacturing exports.According to Leamer & Stern (1970), a country's export performance is influenced by factors such as geographical destination, world export demand, product composition and a country's competitiveness.Unfortunately, the competitiveness of Indonesia's merchandise export is considered low, as the share of natural resource intensive goods and unskilled labour intensive goods are still dominated in the Indonesia export commodities (Rahmaddi R & Ichihashi M, 2012).The exported natural resource as raw material goods indicates that value added in the domestic remain low, according to Giovanni & Levchenko (2012) dependency on primary commodities of country's export could trigger volatility in the short run of GDP.Therefore, integrated efforts in enhancing 16.00% 14.00% 12.00% 10.00% 8.00% the competitiveness of the processed and manufacturing commodity should be taken as an action by the government to develop Indonesian export-oriented industries in the future.

The Coase Theory of Transaction Costs
There are no specific theories which explain trade facilitation.However, trade facilitation in practice is connected with economics through cost channels in trade and also correlated with institutional development.
In fact, the high transaction cost in trade and inefficiency in the process of conducting trade could be potentially reduced through reforms and development of a country's trade facilitation.The literature on the importance of the institutional subcomponent for economic development refers to the theory of transaction costs which was formulated by Ronald Coase.
According to Coase (1992), the effects of high and costly transactions will without doubt hamper the economy.Entrepreneurs have to include transaction costs as a consideration in making decisions regarding their business and production plans.High costs in obtaining information and poorly protected property rights can make the agreements difficult to specify and implement.This may lead to high transaction costs.According to Shirley (2005), the institution is the key factor in determining whether transaction costs are high or low.Countries with interminably high transaction costs are likely to have fewer firms, less investment, less trade, less specialisation and lower productivity.This view is also in line with Rodriguez-Pose's study (2013) stating that local institutions are crucial for economics development.
The institutional features of a country, such as red tape bureaucracy in port and customs clearance, and lack of supporting infrastructure, reflect a negative externality on private commerce.This could increase the transaction costs in trade in a substantial level and adversely affect industrial organisations which in turn has a negative effect on economic growth and trade (Iwanow & Kirkpatrick, 2009).This notion is supported by Deardorff (2001) who argues that the process of international trade is more significantly impacted by hidden transaction costs than by technological factors and endowments.

Dimension of the Trade Facilitation Measure, and the Commodity Classification
Studies of the impact of trade facilitation in general can be divided into two groups on how trade facilitation is measured.The first measure focuses on a specific dimension, whereas the second involves all aspects of trade facilitation into the model.There are several studies which analyse trade facilitation impact by a single aspect known as 'monodimensional models' -for example Hummels (2001) investigated the effect of time on trade, and Helble, Shepherd, & Wilson (2009) studied the gain from reforms in trade policy transparency.'Multi-dimensional models' were initiated by Wilson, Mann andOtsuki (2003, 2005) and they included different measures, such as efficiency of ports, the customs and regulatory environment and implementation of e-business, to examine its relationship with trade flows in the Asia-Pacific region.The objective of using several dimensions is to identify the area that needs to be prioritised by policy makers, rather than focusing on one specific dimension.Moreover, the selected measures are in accordance with GATT articles V, VI, VIII and X which underlie the trade facilitation agreement of WTO.
Both mono and multidimensional study can use aggregate or disaggregate data in the analysis to examine the impact of trade facilitation on the whole sector or in a specific sector of trade.For example, in examining the impact of trade facilitation by using a specific sector of trade, Martinez-Zarzoso and Marquez-Ramos ( 2008) used disaggregated trade data of the 4-digit level of the Standard International Trade Classification (SITC).
The study used a narrow definition of trade facilitation by only including border related elements into the model.On the other hand, Wilson et al. (2003Wilson et al. ( , 2005) ) used aggregate data through the analysis of one digit level of data in the manufacturing sector.This includes commodities in categories 5 to 8 except category 68 in the two digit level of the SITC.Besides using aggregate data, Shepherd & Wilson (2009) also used a different classification of commoditythe 1 digit product classification of the Broad Economic Categories (BEC).
An alternative commodity classification used internationally is the harmonized system (HS).These different classifications of commodity are aimed to capture different features and criteria as there are different statistical and analytical needs.In terms of economic analysis, data taken from the SITC are more suitable due to their coverage which includes the production stage and its related factors.In contrast, the HS classification is based on the commodities' nature, while the BEC classification comprises three primary classes: capital goods, intermediate goods and final goods (Lal, 2012).Since the coverage includes the production stage, the use of the SITC commodity classification is for studying the impact of trade facilitation on Indonesia's export of manufactured goods.

Empirical Studies of Trade Facilitation
To date, studies on the impact of trade facilitation on the economy have focused on international trade flows, and also investigated how reforms in trade facilitation can affect trade flows.In addition to the analysis of the global effects of a wide range of countries' relationships, it is also possible to study the effects in both regionally and in a specific country which are still under research.
A study at the regional level was conducted by Shepherd & Wilson (2009) who analysed the advancement and indicators of trade facilitation in the ASEAN region using the gravity model of these following indicators: the quality of sea and air ports, irregular payments and the level of rivalry in Internet Service Providers (ISPs).They found that regional trade is sensitive to the quality of transport infrastructure and ISP.This is also supported by the counterfactual simulation which showed that the benefits from trade facilitation reforms are greater than the benefits from reduction in tariffs.Following the approach taken by Wilson et al. (2005), the simulation was constructed using five different reform scenarios in order to provide a priority list of recommendations.A recent study by Felipe & Kumar (2012) analysed the relationship between trade facilitation and bilateral trade flows of the Central Asian countries using the gravity model.They found that infrastructure had the most significant contribution to higher trade flows followed by logistic costs and customs environment e.g.efficiency in time and costs of customs.
Another study conducted by Pomfret & Sourdin (2009) analysed trade facilitation using a different approach.It focused directly on trade cost issues by using data from the Cost Insurance Freight (CIF) and Free On Board (FOB) on Australian imports which indicates the international shipping costs between trading countries.By examining ASEAN country exports to Australia, the authors reported that trade costs had reduced significantly during the 1990s and 2000s from 10% of the average ad valorem costs in 1990 to less than 4% in 2007.This is related to the formation of the ASEAN Free Trade Agreement (AFTA) in the region that takes into account the liberalisation of trade by reducing tariffs and improving the trade facilitation environment.
However, such an approach only captures the international transport costs and does not explain the broader range of trade costs which have become the underlying focus of trade facilitation.
Dennis & Shepherd (2011) studied the effect of trade facilitation on export diversification in 118 developing countries taking into account the export costs and the market entry costs.The result shows that lowering export costs and market entry costs by 10% can stimulate export diversivication by 3 to 4%.There are very few studies of trade facilitation in Indonesia.Damuri (2006) examined the efforts of Indonesian trade facilitation in relation to negotiations in the WTO.This study was done by matching the measures taken by the government with a reference to GATT articles through a survey involving the private sector.The author found that simplification and automation of documentation required in trade procedures are the most important measures to take in order to improve trade facilitation.In addition, illegal charges must be solved before they hamper competitiveness.A recent study by Tambunan (2013) focused on accessibility and usefulness of trade facilitation for export-oriented in small and medium-sized enterprises (SMEs).The author concluded that there were some main factors of low export performance especially for SMEs located in rural areas, such as a lack of information about export markets, available trade facilitation and financial support to increase production capacity.This result is in line with an earlier study of Tambunan (2007Tambunan ( , 2011) ) which found that limited working capital and lack of promotion were the main constraints for Indonesian SMEs to export.

METHODOLOGIES
The main focus of this study is to measure the impact of trade facilitation in Indonesia as an exporter country and in relation to the conditions of trade facilitation in 30 main importing countries.This study uses the data from 2010 to 2014 due to the limitation of data availability.
In order to undertake quantitative analysis of trade facilitation measures and indicators of efforts, the data are divided into four distinct categories following Wilson et al. (2005Wilson et al. ( , 2012)): (i) port efficiency to measure the quality of port and air transport infrastructure, (ii) customs environment to measure the efficiency in time and costs of customs, (iii) regulatory environment to measure regulation development and government transparency and (iv) service sector infrastructure to measure the presence of domestic infrastructure and technology in supporting economic activity.
Each of the trade facilitation indicators was constructed using two relevant surveys for constructing inputs and then it was averaged to obtain the value of each trade facilitation indicator.Because those surveys data are using a different ranges of response, recalculating the inputs index with benchmarking to the country with the highest performance as best practice will allowed those index into a comparable basis.The index ranges from 0 to 1 with the maximum value 1 referring to best-practice country, this indicated the level of performance of other countries.Table 3  Gravity models have been used extensively as an approach to analyse bilateral trade flows.The classical conception of the gravity model was originally reported by Tinbergen (1962) and Pöyhönen (1963), who were inspired by Newton's law of universal gravitation, to explain the bilateral trade flow between trading partners.According to Leamer & Levinsohn (1995), modeling trade between two countries should include several variables, such as GDP and GDP per capita, as a proxy for a country's economic 'mass' to indicate market size.The economic distance between countries is also included to capture the effect of transportation costs.Other variables can also be added into the model in order to weigh the barriers in trade, for example trade policy factors, a common language and the historical and geographical connections between countries.Such a basic formulation has evolved as the objective of hypothesis testing.In this regard, tariff and trade facilitation indicators, as well as additional factors can be added into the model.
The general form of the gravity equation, as used in the study of Anderson & Wincoop (2003), can be written as follows: Where is the variable of export value from exporter country i to importer country j, while the notation and are the GDP of country i and j divided by Y which denotes world GDP.The terms of trade costs are included with the notation of , while denote the ease of market access and/or multilateral resistance, while σ > 1 is the elasticity substitution of all goods.In this study, the basic model was estimated by first transforming all variables into natural logarithms form so the estimate parameters indicate the magnitude of elasticity of manufacturing export to each independent variable.The model presented is as follows: ln(EXP jt ) = a 0 +b 1 ln(100+TARIFF jt )-ln ( 100  denotes the weighted applied tariff rate in ad valorem terms from country j to Indonesian exports in year t, while represents the real exchange rate of Indonesia to country j currency in year t.
Trade facilitation measures are in the terms of which denote the importing country j's indicators, while denote Indonesia as the exporting country indicators of port efficiency, both the regulatory and customs environments and service sector infrastructure, respectively.For customs environment indicators, the difference between exporter and importer are in the constructing indicators, whereas the cost and time needed to import are used in the importing country j in year t.Also, cost and time needed to export are used in Indonesia as the exporting country in year t.
The term denotes Gross Domestic Product, while denotes total population of the importing country j in year t.These variables are used as a proxy for importer market size in manufacturing commodities.Another variable is the geographical distance or bilateral distance, in this study the distance between capital cities of Indonesia to country j's is used and denoted as as taken from the Centre d'Etudes Prospectives et d'Informations Internationales (CEPII).The binary variables of the ASEAN and European Union (EU) preferential trade agreements are used to capture the effect of trade partnership between Indonesia and two major of regional partners.
The incorporation of trade facilitation indicators into the standard gravity model has been used in various studies.Wilson et al. (2003) analysed the empirical relationship between trade facilitation indicators and international trade flows among the APEC member countries in the period 1989 to 2000 by focusing on four aggregate trade facilitation indicators in the importing country only, it was then regressed with other economic variables and distance.They found that port efficiency had the largest and positive impact on intra-APEC trade flows, while the other variables also positively contributed to trade flows but in smaller coefficient, except for the regulatory environment which was found to have a negative impact.This study was then extended by the authors in 2005 by adding trade facilitation variables of exporting countries, but excluding the customs environment variable.The results indicated that all trade facilitation indicators had a positive impact with higher trade flows.The difference in the resulting sign of regulatory environment variable is due to the differences of the approaches in constructing the trade facilitation measures that is used.
As this study aims to measure the impact of trade facilitation efforts in Indonesia as an exporter country, as well as the conditions in the 30 main importer countries on Indonesia's export performance.It is important that the subject of analysis has a large share of Indonesian merchandise export.For this reason, this study uses manufacturing commodity, the second largest share of Indonesian merchandise exports after the fuel and mining commodity, which is also prioritised by the government to improve performance.
The data was collected from secondary sources during 2010 to 2014 covering the 30 main importing countries of Indonesia's manufacturing commodities.This study uses bilateral trade flow data of Indonesian exports taken from the United Nations statistics division of Commodity and Trade Data base (UNCOMTRADE).The defined categories of manufactured goods are from the Standard International Trade Classification (SITC Revision 4) with categories 5 to 8 at the one-digit level except category 68 (non-ferrous metal) at the two-digit level.The export value is then adjusted to real terms by using Indonesian data of the Producer Price Index (PPI) with the 2005 value as a base year taken from the Bank Indonesia data source.
Tariff data used in this study was taken from Trade Analysis and Information System (TRAINS) of the United Nations Conference on Trade and Development (UNCTAD).Import tariffs from the four commodity categories of manufacturing were used, specifically with the weighted average tariff rates in the periods 2010 to 2014 as applied by these 30 main importing countries.Data on Gross Domestic Product (GDP) were in constant 2005 US dollars, while data of total population were also for the period 2010 to 2014, and taken from the World Development Indicators (WDI) generated by the World Bank.
Another key variable used in this study is the exchange rate, with the nominal data taken from the United Nations Conference on Trade and Development statistic (UNCTADstat).The annual data of Indonesian Rupiahs against importing countries currencies were also collected for the years 2010 to 2014.Afterwards it was deflated using Indonesia's consumer price index and each importing country's consumer price index with the 2005 value as the base year in order to obtain the real terms of exchange rates.This real term of all observed variables was used to address the inflation effect which may create bias in the interpretation of results.

RESULTS AND DISCUSSION
Estimated results of the gravity model are shown in Table 4.The model was run by using ordinary least square (OLS) and by employing the fixed effect (FEM), also random effect model (REM) with panel data regression to compare the differences.A statistical test was carried out using the Hausman test, followed by the Breusch and Pagan Lagrangian-multiplier (LM) and the Pasaran cross-sectional dependence test in order to select the best model to analyse the impact of trade facilitation on Indonesian export performances with its main trading partners.
According to Baltagi (2008), a difference estimation result between fixed effect and random effect models is yielded if the observed time (t) is relatively small while the observed individual (n) is large.A specification test using the Hausman test indicates the random effect model is appropriate to explain the outcome.The Breusch and Pagan Lagrangianmultiplier (LM) test was conducted to examine whether the pooled regression model is more appropriate than the random effect model, Table 5 indicates that the random effect model is more appropriate to explain the regression.5) shows that there is no serial correlation in the model.
Estimation results from three different regession methods are reported in Table 4. Overall, the preferred model, which is the random effect model, indicates good performance.Its probability value shows that model significance is in a 5 percent alpha (0.000 < 0.05), while the R-squared statistic accounts for around 83% of observed variation between dependent and independent variables within the selected sample.
The estimated results of the gravity model regression presented in Table 4 indicate different levels of significance for the three types of estimations performed.The GDP variables for importers were found to be consistent across the three estimations with all being positive and significant at 1 percent in OLS, FEM and REM.Such a result explains that the growing size of a market's economy would generate higher Indonesian manufacturing export performance.The distance variable was found to be significant and had the expected negative signs in both OLS and REM.This means that distance adversely affects bilateral trade.Tariff and exchange rate variables were not statistically significant in the three regression estimations, except that exchange rate was negative and significant at 10 percent in the FEM.The constructed trade facilitation indicators also display considerable variation, but not all indicators were found to be statistically significant.Specifically, the port efficiency variable was not significant in all three models of estimation, whereas the customs environment, regulatory environment and service sector infrastructure indicated a different level of significance for the three estimations performed.
As a result of the specification test, this study focuses on results from the REM as it is the best model to explain the data variation.The REM estimates that customs environment (CE) in both exporter and importer countries was positive and significantly associated with the Indonesian manufacturing export performance.It was significant at the standard 1% for the CE of the importer country and at 5% for Indonesia as the exporter country.Estimated coefficient magnitudes of the Indonesian customs environment were greater than the coefficient of importing countries by 1.13, while the importer CE coefficient was 0.54.This high and significant coefficients suggest that the customs environment plays an important role in Indonesian manufacturing export performance.However, the Indonesian regulatory environment has a negative and significant effect on manufacturing export performance with a relatively high coefficient of -2.98.This indicates an inverse effect in the tightening of corruption and transparency through government regulation.On the other hand, only the ASEAN binary variable was found to be statistically significant under both OLS and RE estimation, while the EU dummy variable was statistically insignificant.
Regarding statistically insignificant variables in this study, namely port efficiency and service sector infrastructure in both exporter and importer countries and the regulatory environment in importer countries, it can be concluded that there is not enough evidence that these trade facilitation indicators influence Indonesian manufacturing export performance with its main trading partners.Therefore, further study is recommended to use a different approach of trade facilitation measures and to conduct more observations in the analysis for gaining a better understanding in the impact of such variables on manufacturing export performance.
Based on the estimation results in Table 4, and the description above, two trade facilitation indicators which significantly affect the Indonesian manufacturing export performance are the customs and regulatory environments.The coefficient variable of the customs environment in the importer countries showed a positive association of 0.54.This suggests that each one percent of an improvement in the degree of importer customs environment which is closer to the best practice country's conditions will lead to an increase in Indonesian manufacturing export performance amounted to 0.54 percent, ceteris paribus.The improvement would be gained through reduction in time and costs to import goods in the importer country.
The impact of Indonesia's trade facilitation on export performance would affect two channels.Firstly, improving the Indonesian customs environment will positively effect manufacturing export performance.With a coefficient of variable of 1.13, this mean for each one percent of improvement in the degree of Indonesian customs environment closer to the best practice country's conditions will lead to an increase in the Indonesian manufacturing export performance of 1.13 percent, ceteris paribus.The increased performance would be achieved by improving efforts to ease flows of export through customs which could reduce time and costs needed for traders to export from Indonesia.
Secondly, the coefficient variable of the Indonesian regulatory environment was -2.98, meaning that each one percent of an improvement in the degree of the Indonesian regulatory environment closer to the best practice country's conditions will lead to a decrease in the Indonesian manufacturing export performance of 2.98 percent, ceteris paribus.In other words, tightening regulation will lead to greater corruption in the public sector and negatively affect the Indonesian export performance.This result is in line with the findings of Wilson et al. (2003) showing that high and strict government regulations can reverse the positive effects of other measures.Further studies should be undertaken in this area using a different approach to construct regulatory environment measures in order to find out the association that exists.

CONCLUSION AND POLICY RECOMMENDATIONS
Trade facilitation has become a global concern in the last two decades as reforms and developments in this area are considered to have a positive impact on greater trade flows.Indonesia has suffered a trade deficit since 2012 with a government policy on banning raw material exports which contributes to lower merchandise export performance.Manufacturing commodities constitute the second largest share of Indonesian merchandise exports, with the improved trade facilitation it is expected to generate the competitiveness of Indonesian processed minerals commodity which can lead to higher export performance.Hence, this study examined a series of regressions using gravity models with panel data to identify indicators that statistically and significantly affect exports in the period 2010 to 2014.The gravity model was applied to measure the impact of trade facilitation in Indonesia and its 30 main trading partners on the Indonesian manufacturing export performance.
Based on the analysis conducted, the customs environment in both Indonesia and its trading partners has a positive and significant impact on Indonesian manufacturing export performance.The constructing indicators of trade facilitation measures in this area are the time and cost in undertaking export for the exporter country, while the time and cost of import was observed as the importer country's indicators.Prioritising efforts to make the customs environment more efficient in time and costs will likely enhance the Indonesian manufacturing export performance.This provides an insight for the government to focus for reforms and development of trade facilitation measures.
The results of this study also indicate that Indonesia's regulatory environment is not optimal in facilitating trade and has an adverse impact on manufacturing export performance, where through the simplification of regulations and less corrupt behaviour in public sector is negatively associated with the export performance.A related aspect which needs to be considered by the policy makers is the openness of information and public transparency.Incomplete information of evolving regulations could hamper trade and create lag time for traders to adjust.However, further study is required to use different approaches to better understand such impact.
It is also suggested to use a different approach to study the impact of port efficiency and service sector of infrastructure on export performance, as these were not statistically significant in this study.On the other hand, the estimated results indicate that improving trade partnerships in the ASEAN region will be beneficial to increase the Indonesia's export performance.The upcoming regional agenda is to fully implement the ASEAN Economic Community by the end of 2015.It is expected to stimulate greater trade flows among the members, and Indonesia especially.
Although new insights into the impact of trade facilitation on export performance has been provided in this study, Indonesia should improve and develop all of trade facilitation measures in order to better engage with the global trade system and cope with evolving agreement and programs at both the multilateral and regional levels.In conclusion, reforms and development in trade facilitation not only provide benefits for traders, but also for the economy and the society through more efficient and timely trade.
