ANALYSIS OF INDONESIAN TRADE: CASE STUDY AFTER THE AFTA AGREEMENT

The ASEAN Free Trade Area (AFTA) began in 1993. The hope of this agreement was that intra-ASEAN trade to grow rapidly turned out to be slow. Based on data from the ASEAN Secretariat in 2016, intra-ASEAN trade experienced a slow journey in the range of 20-24 percent over the past few years. This study empirically analyzed the influence of AFTA on Indonesia’s trade structure towards ASEAN using TSI, GL / IIT, and CTB index. In the pe - riod of 2012-2017 Indonesia’s trade balance against ASEAN suffered a loss. Despite the loss, there was a decrease in trade balance losses from 2015-2017 (after AFTA). To analyze trade there are 10 commodity classifications determined by SITC revision 3. Based on the results of the TSI analysis, there is a specialization of 6 commodities trading which have high export power. The CTB analysis is only commodities of Chemicals and related products, n.e.s, which contribute positively to Indonesian trade. For IIT analysis there are 4 commodities where the average IIT index increases after the AFTA agreement.


Introduction
Asean Trade Agreement (AFTA) is a comprehensive world-class bilateral agreement that substantially liberalizes trade between ASEAN countries.AFTA removes or reduces barriers to investment and trade between ASEAN countries.ASEAN is growing into an economic region that is considered by the world.If the total GDP of ASEAN countries is ranked the 7th largest in the world and becomes the 3rd largest in ASEAN Secretariat (2016).It can be seen from foreign investment funds that entered ASEAN around 136 million US dollars in 2014.ASE-AN's achievements are getting better where 2007 to 2014 have a total trade value of almost 1 trillion US Dollars, where the largest share comes from ASEAN countries internal trade of 24, 1% (ASEAN Secretariat, 2016).
Indonesia's GDP is the largest in ASEAN, but the size of Indonesia's exports and imports is not the largest in ASEAN.ASEAN imports were dominated by Singapore, Malaysia and Thailand during the 2011-2015 period.If imported and exported in Indonesia is ranked 3rd under Singapore and Malaysia.In 2015 Indonesia's exports to ASEAN were recorded at 17.15% lower compared to Singapore and Malaysia, respectively 24.72% and 18.14%.However, in 2011-2015, several countries experienced declining exports except Vietnam, the Philippines and Myanmar.Indonesia experienced a decline in exports in 2011 of 19.09% to 17.15% in 2015.

The condition of imports in Indonesia is not much different from exports where Indonesia ranked 4th under Singapore, Malaysia and Thailand.In 2015 Singapore in terms of imports ranked first at 30.06%, Malaysia 23.99%, Thailand 19.31% and Indonesia recorded at 12.43%.In the 2011-2015 period, imports of several countries experienced declines such as Indonesia, Malaysia and the Philippines.Indonesia from 2011 at 16.27 percent fell to 12.43 percent in 2015, Malaysia from 26.06 percent to 23.99 percent; and the Philippines from 4.52 percent to 3.87 percent.While several countries such as Singapore, Thailand and Vietnam experienced an increase.Singapore from 2011 was 26.60 percent up to 30.06 percent; Thailand from 19.31 percent to 21.41 percent; and Vietnam from 1.40 percent to 5.34 percent.
This study empirically analyzes the influence of AFTA on Indonesia's trade structure towards ASEAN using TSI, GL / IIT, and CTB index.It evaluates the comparative advantage of industrial or product exports and its competitiveness by TSI, measures the intra-industrial trade of individual products or goods that show export potential at the macroeconomic level and the difference between the industry trade balance and the same industrial trade by GL and IIT and measure the contribution to the national trade balance made by industry by CTB.Through this, the impact of AFTA on the trade structure between Indonesia and ASEAN is ensured.An overview of the structure of Indonesian trade is possible by considering the import and export of structural factors of all goods in Indonesia and ASEAN.Furthermore, this paper examines which products / industries contribute to the trade balance of the two countries in such agreements.The broad and deeper meaning of the results is discussed as follows.

AFTA (ASEAN Free Trade Area)
ASEAN free trade is an international trade between ASEAN countries which includes the countries of Vietnam, Laos, Cambodia, Brunei Darussalam, Malaysia, the Philippines, Thailand, Singapore, Myanmar and Indonesia.International trade is a cross-country trade that has the goal of getting an increase in income and a decrease in production costs which makes the price of goods cheaper (Mirza, 2016).

Common Effective Preferential tariff (CEPT)
The decline to the elimination of import tariffs has an impact on the level of domestic consumption.The lowering of import tariffs has an effect on the price of goods coming in lower and consumers do not face a high price.This is in accordance with the explanation of Adam Smith's book The Wealth of Nations (Skusen, 2015) which states Adam Smith's disapproval of the existence of high tariff rules, quotas and rules that are able to limit trade because it results in restrictions on living standards due to high prices.the price of goods that should be accessible for consumption if there are no tariffs and trade restrictions.The enactment of free trade for ASEAN countries also creates fierce competition in producing goods or services in the territory of ASEAN countries.Facing this, there is one theoretical basis put forward by Adam Smith in the book The Wealth of Nation in Skusen (2015) concerning the concept of absolute excellence which states that each country must have the best quality products to be able to compete and prosper from an economic perspective on free market.This concept was later developed by Ricardo in Skusen (2015) in the form of a comparative advantage concept.The concept of Ricardo's comparative advantage requires the State to specialize in production at the lowest price with production costs incurred by other countries.So that these two advantages are needed to create and balance market competition.

Indonesian Trade Exchange Rates
Trade exchange rates occur starting with trading from one country to another.Hermawan in (Mirza, 2016) states that the ratio of international exchanges is said to be balanced depending on the desire of a country in offering and buying commodity goods at relative prices.
The trade exchange rate here is the export price index of a country on the import side.
The trade exchange rate is calculated by dividing the export value by import then multiplying by 100.If the value of more than 100% can be interpreted that the State collects more capital in exports than issuing capital to imports (Salvatore, 1996).

Balance of trade
The net export trade balance is the export value minus the import value (Mankiw, 2000) NX = EX -IM The trade balance and net capital outflow are the same, equal to savings minus investment.The Trade Balance is a record of the export and import transactions of a country.A trade balance is in three conditions, namely, surplus, deficit and balance.The condition of the trade balance is said to be surplus if exports of goods are greater than imports (Pujoalwanto, 2014).Deficit is said if the value of exports of goods is smaller than imports and is said to be a balanced trade balance if the export value of an item is equal to the value of imports made by the industry.Indonesia's trade balance against ASEAN can be categorized as bad.Only in 2004 did Indonesia experience a trade surplus of 1,308.24USD billion (ASEAN Statistical, 2017).After 2004 Indonesia always experienced a trade balance deficit against ASEAN.Since AFTA began in 2016 Indonesia's balance sheet began to improve.Although Indonesia's trade balance deficit from 2015 to 2017 has decreased the trade balance deficit.From -5,340.45USD billion in 2015 to -39.30USD billion in 2017.This shows that the AFTA has a good influence on Indonesia's trade balance.

Efficiency and Equity
Specializes when experiencing success and success in increasing creativity and productivity.Based on the broader market and demand will be increasingly diverse so that market players will naturally try to meet market demand.To get a higher output, micro-economic actors make a more efficient economy to increase macro-economic competitiveness.
Increased capital, technology and productivity will have a positive effect on improving living standards according to J B Say in (Skusen, 2015).This will happen to countries that have absolute advantages and comparatively benefit as outlined in the theory of efficiency.The inverse of a country that has no unity will suffer losses because it has a very high dependency on other countries, this is called the equity theory.While efficiency will encourage increased output to get high profits for those countries that have excellence.

Data and Research Methods
In the next section, this study will analyze the implications of AFTA based on 4 methodologies: Trade Specialization Index (TSI), Grubel Lloyd / Inter-Industry Trade Index (IIT), Contribution to the Trade Balance Index (CTB).The definition of this methodology is explained below.To analyze trade there are 10 commodity classifications determined by UNCTADSTAT SITC revision 3. Data used per commodity is obtained from the 2-digit up to 8-Digit (AHTN) ASEAN STATS Trade in Goods (IMTS), Annually, HS from 2012-2017.

Trade Specialization Index (TSI)
TSI evaluates the comparative advantage of industry or export products and their competitiveness (Sujová et al., 2015).In other words, the trade specialization index is a value that shows the comparative advantage of a product, using the value of exports and imports of a country's products (Kang, 2016).TSI is calculated using the following equation: the same industry trade balance and total trade industry.To make easier comparisons between industries or countries, indices are presented as ratios where the denominator is total trade (Leitão and Faustino, 2008).
- : Describes the specialization of trade for j products from countries i   : Explain j product exports from country i  : Describes j product imports from country i TSI is always between the minimum value -1 and the maximum value +1.For a particular country and product, TSI will be -1 if there is only import and no export (Perfect Import Specialization).TSI will be +1 if there is only export and no import (Perfect Export Specialization).TSI will be 0 for balanced trade.This is used as an index to measure export competitiveness.If it is greater than 0, that means the product group has a trade surplus and export competitiveness.
The closer the TSI value is -1, the weaker the competitiveness of product exports in the global commodity market.Alternatively, if the TSI index is bigger, it means having strong competitiveness and if the value is 0 means that the number of exports equal to imports translates to the reality of the activity of intra-industrial trade.However, if it appears between -1 and 0, that means the level of import specialization is high.TSI can also be an indicator of relative comparative advantage in exports and serves as an indicator for evaluating countries designed for special zones.

CTB (Contribution to Trade Balance (CTB) Index)
When, CTB> 0 means that the actual surplus is higher than expected or the trade deficit is relatively lower than expected, and the industry or commodity group contributes positively to the overall trade balance.Or, this in the real sense means it is a comparative advantage in trade.On the other hand, when CTB <0 means that industry and commodity groups contribute negatively to the total trade balance because actual results are compared with negative expected results or lower than expected.This in the real sense shows that there is a comparative loss for trading.

Grubel-Lloyd (GL) / Intra-Industry Trade (IIT)
Index The GL index measures the intra-industrial trade of a product or item that shows export potential at the macroeconomic level.It was modified for evaluation at the industrial level and the calculation shows the level of commodity representation in a country's intrasectoral international trade.IIT levels are generally measured by what are called the Grubel and Lloyd indices (1975).IIT is the difference between CTB as follows; The GL index is now used to measure the level of intra-industrial trade among countries.The intra-industrial industry trade index between two countries is defined as: The IIT index has a value always greater or equal to zero and less or equal to one (0≤IIT≤1).The IIT index is equal to 1 if all trade is a type of intra-industrial trade and if IIT is equal to 0, all trade is a type of industrial trade.The closer the index value to 1 is the greater the degree of intra-industrial trade.However, it should be noted that the GL index is influenced by a measure of trade imbalance.Sharma (1999) determined that the symmetrical index between countries and according to (Yoon & Starks, 1995), the index lies between 0 and +1.

Grubel-Lloyd (GL)/Intra-Industry Trade (IIT) Index
To analyze the level of integration and trade links between Indonesia and ASEAN, use the value of IIT (Intra Industry Trade).With high values, it points to the close linkages of the country.With the value of IIT, it can identify patterns of trade between Indonesia and ASEAN.Data on export values and import values are obtained from the ASEAN STATS Trade in Goods (IMTS), Annually, 2-digit HS up to 8-Digit (AHTN), in US $.The commodity analyzed in the discussion is a commodity based on ASEAN STATS.The value of the results of a high IIT analysis (index = 1) indicates a two-way trade that means Indonesia and ASEAN are exporting and importing.Meanwhile, a small IIT value (Index = 0) indicates that there is a one-way relationship in which Indonesia only acts as an exporter or importer country.The table below shows the TSI of all commodities traded between Indonesia and ASEAN countries Commodities and transactions 0,21 0,12 0,07 0,47 0,31 0,17 0,14 0,32 0,23 The table above shows the GL / IIT Index calculated for various items traded before and after signing the AFTA between Indonesia and ASEAN during 2012-2017.The degree of integration in each sector is measured by the Intra-Industry Trade index (IIT).The magnitude of the IIT illustrates the magnitude of intraindustry trade, namely the amount of export of imported commodities from the same industry.IIT is the difference between CTB as follows; The GL index is now used to measure the level of intra-industrial trade among countries.This shows that all traded items have a high level of import specialization during 2012-2015 (GL index is close to 0).There are 4 commodities where the average IIT index increases after the AFTA agreement.The 4 commodities are Manufactured Goods, Machinery and transport equipment, Miscellaneous manufactured articles, Commodities and transactions.However, there are also some commodities that experience a decline in index value.The decrease in the worst index value for Mineral fuels, lubricants and related materials.In the year before 2012-2014 the average value of these commodities was at a value of 0.39.However, in the year after the 2015-2017 afta agreement decreased to -2.31.Overall there is intra-industry trade with the amount of exports between Indonesia and ASEAN (IIT> 0)

Conclusion
This study empirically analyzes the influence of AFTA on Indonesia's trade structure towards ASEAN using TSI, GL / IIT, and CTB index.It evaluates the comparative advantage of industrial or product exports and its competitiveness by TSI, measures the intra-industrial trade of individual products or goods that show export potential at the macroeconomic level and the difference between the industry trade balance and the same industrial trade by GL and IIT and measure the contribution to the national trade balance made by industry by CTB.Through this the impact of AFTA on the trade structure between Indonesia and ASEAN can be ascertained.An overview of Indonesia's trade structure towards ASEAN is possible by considering import and export structural factors of all goods.Furthermore, this paper examines which products / industries contribute to the trade balance in such agreements.The broad and deeper meaning of the results is discussed as follows.By promoting competition and efficiency.
The first analysis, namely TSI, found that items such as Food and live animals, Beverages and tobacco, Mineral fuels, lubricants and related materials, Animals and vegetables oils, fats and waxes, Miscellaneous manufactured articles, Commodities and transactions were designated for export.Meanwhile Crude materials, inedible, except fuels, Chemicals and related products, n.e.s, Manufactured Goods and Machinery and transport equipment are specifically for imports.Of the several items examined by TSI there was no change in the index specialization.Because before and after AFTA there was no significant change in Indonesian trade specialization.
Analysis of the magnitude of the IIT illustrates the magnitude of intraindustry trade, namely the amount of export of imported commodities from the same industry.Overall, of the 10 commodities, only 1 commodity has a value of <0.However, there are also some commodities which experience a decrease in index value.The decrease in the worst index value for Mineral fuels, lubricants and related materials.In the year before 2012-2014 the average value of these commodities was at a value of 0.39.However, in the year after the 2015-2017 afta agreement decreased to -2.31.Overall there is intra-industry trade with the amount of exports between Indonesia and ASEAN (IIT> 0) The third analysis, CTB serves to show the comparative advantage of commodity goods traded by Indonesia against ASEAN.There is a comparative loss (CTB <0) of 10 commodities 9 of which have comparative losses.The nine commodities are Food and Live Animals, Beverages and Tobacco, Crude materials, Inhibited, except fuels, Mineral fuels, lubricants and related materials, Animal and vegetables oils, Fats and waxes, Manufactured, Machinery and transport equipment, Miscellaneous manufactured articles Commodities and transactions.The biggest comparative losses are Machinery and transport equipment commodities where the average CTB value reaches -9.2.However, trading in Chemicals and related products, n.e.s from 2012-2016 suffered a comparative loss but in 2017 experienced a surge in exports reaching 5.55 from the previous year of -0.3.. Finally, products / items with CTB> 0 indicate they make a positive contribution to Korea's trade balance and vice versa.
