| Summary: | 碩士 === 南華大學 === 管理經濟學系經濟學碩士班 === 96 === Taiwan’s automobile components industry, a long-term government protective industry, is expected to be affected enormously by Taiwan’s accession to the WTO because the reduction of the average nominal tariff rate as well as the elimination of the local content and sourcing requirements on production have made the global automobile components industry become more competitive. To counter the potential shocks associated with Taiwan’s WTO entry, both government and manufacturers have long been implementing an array of responsive measures, as a result, the WTO membership may launch an opportunity for automobile components producers to facilitate industrial upgrading and business restructuring.
Therefore, the purpose of this study is to analyze how the productivity of automobile components producers changes by Taiwan’s accession to the WTO. To achieve this goal, we estimate the parameters of a production function for the automobile components industry of Taiwan, and then use those estimates to analyze the evolution of productivity. The empirical results show that capital investments and labor inputs have a significant, positive impact on firms’ sales respectively. The productivity of automobile components manufacturers increased significantly after Taiwan’s accession to the WTO. The weighted average of firm-level productivities by output and capital are higher than the un-weighted average of firm-level productivity; however, the covariance between firm-level output and firm-level productivity as well as correlation coefficient between firm-level capital and firm-level productivity are negative after 2001. Finally, there is an increase in the efficiency of the allocation of labor inputs after 2002.
