Concentration, Profitability and Trade in a Simultaneous Equation Analysis: The Case of Taiwan
首次使用四方程联立系统，研究对外贸易对台湾制造业市场结构和绩效的影响，发现国有企业显著影响市场结构，进口控制措施影响进口强度并抵消进口对集中度和盈利能力的潜在影响，而贸易强度主要由比较优势而非市场力量解释。
This paper is the first attempt to use a simultaneous four-equation system to study the role of foreign trade in the analysis of market structure and performance, and the determinants of trade intensity in a newly industrializing country-Taiwan. A cross-sectional analysis is carried out with the manufacturing censuses of 1976. The results indicate that public enterprises significantly influence market structures and performance. Also, import control measures influence import intensity significantly and offset potential impacts of imports on concentration and on profitability. However, trade intensity is mainly explained by comparative advantage rather than market forces (concentration and profitability).
