Abstrak: Thailand and China play important roles in the trade of natural rubber because both countries are respectively the biggest exporter and importer of natural rubber in the world. However, there are many problems such as supply shortage of natural rubber to meet the demand for natural rubber and unstable prices. Therefore, it is necessary to examine how the behaviors of both countries affect the supply, demand and price of natural rubber in international trade in particular technical specified rubber (TSR) where this type of rubber have the greatest amount traded between the two countries. This study has two main objectives that include the following: (1) to analyze the factors that influence the export supply, import demand and price for technical specified rubber in Thailand and China, and (2) to analyze the impact of internal factors and external factors alteration to the export supply, import demand and price for technical specified rubber in Thailand and China. This study used econometric analysis and implemented two stage least squares (2SLS) method and simultaneous equation model and used time series secondary data from 1990 to 2010. The results showed that: (1) Thailand’s supply for TSR exports to China was influenced by amount of TSR Thailand export to China in previous year and amount of TSR Thailand production, while Thailand’s supply for TSR exports to non-China was influenced by amount of TSR Thailand production and amount of TSR Thailand exports to China, (2) China’s demand for TSR imports of Thailand influenced by China’s participation in WTO, amount of automotive production in China and China’s real price import of TSR, while China’s demand for TSR imports of non-Thailand influenced by amount of China’s TSR imports from non-Thailand in previous year, amount of automotive production in China and import tariff in China, and (3) world TSR real prices was influenced by world TSR real price in previous year, amount of exports supply of the world in previous year and amount of imports demand of the world, while real price TSR exports of Thailand was influenced by world TSR real price, amount total of TSR Thailand exports and USA fuel real price, while real price TSR import of China was influenced by world TSR real price ratio and real price TSR import of China in previous year. Historical simulation and forecasting simulation results show that increased production quantities of TSR policy in Thailand and abolition of import tax of TSR policy in China performed within TSR rubber trade between Thailand and China because it enabled to increase foreign exchange for Thailand's technical specified rubber exports.

Judul: Competitiveness Analysis and Factors Affecting Trade Flow of Natural Rubber in International Market
Abstrak: Natural rubber is one of the plantation commodities, which plays an important role in the economic development of many countries. This commodity also provides job opportunities for many people, primarily for smallholder farmers. The supply of natural rubber in the world market is dominated by Thailand, Indonesia and Malaysia. According to UN-Comtrade, the natural rubber export share in 1987, Malaysia is the largest exporter. By period of 1990, however, the condition of trade had started to change, allowing Thailand and Indonesia to shift the position of Malaysia. This change was due to the improvement of natural rubber production in Thailand and Indonesia. Moreover, the Malaysian production decreased due to several factors. This situation illustrates the increasing competition between the three major producers of natural rubber in the international market over the last several decades. Thailand, Indonesia and Malaysia differ in their individual export destinations. However, according to the IRSG data, these three producing countries all exported to ten primary importing countries. As mentioned above, the competition between the main exporting countries is relatively high. Therefore, it is necessary for Thailand, Indonesia and Malaysia to individually focus on improving the quantity and quality of the product in order to remain competitive in the international rubber trade. According to the background information and problem statement, the aims of this research are, to analyze the competitiveness and the level of competition of the three major exporters of natural rubber in the international market and to identify the determinants that influence natural rubber export in international market. All data used in this study is secondary panel data, which is a combination of time series data and cross-sectional data. Time series data includes annual data from 2003 to 2013, while the cross-sectional data covers ten major export destinations of the three main natural rubber exporting countries, with the largest export volumes going to the United States, Japan, China, Singapore, the Republic of Korea, Germany, Canada, Brazil, India, and Belgium. The data used were obtained from Statistics Indonesia (BPS), the International Rubber Study Group (IRSG), the United States Department of Agriculture (USDA), the Centre d'Etudes et d'Informations Internationales prospectives (CEPII), UN Comtrade, the World Bank, and FAOSTAT. First method is Revealed Comparative Advantage (RCA). RCA is a method of analysis for determining the competitiveness of a player, while taking into account the comparative advantage of an individual, organization or country. The performance of natural rubber exports from exporting countries to importing countries is a variable that is measured by calculating the share of natural rubber exports to total exports of all commodities to destination countries, compared with the share of world exports to the destination countries. So that it can be quantitatively the ability or inability of three main exporting countries compete in international trade. And the second method is gravity model. The gravity model is used to analyze the economic factors that affect the flow of trade between two countries. According to Lineman (Lapipi, 2005), the gravity model is an econometric model that is used to analyze the effects of economic integration on trade, as well as
