This study explores how the automotive value chain has evolved in Thailand since the 1990s. Trade in value added analysis is applied to international input-output data. Moreover, the method of value chain mapping is introduced to illustrate the upstream and downstream transactions of goods and services along the value chain. The results show that international linkages have been strengthened by the expansion of production networks in East Asia, whereas domestic linkages started to decline after 2000. In addition, the value chain mapping analysis indicates that the Thai automotive industry achieved high self-sufficiency in automotive inputs, but still depended heavily on imported basic metals.
