台湾对大陆产品提高关税的理论模型分析——从要素收入分配扭曲效应出发的研究

The Model to Analyze a Raising up Tariff by Taiwan to Products from Mainland of China——A Study from the Effect of Factor Income Distortion

台湾如果对大陆产品提高关税会扭曲岛内要素收入分配的格局。本文在一个使用两种生产要素资本和劳动并生产两种商品高技术产品和机制品的一般均衡模型中,考察短期内和长期内上述关税提高会对两种要素的收入产生怎么样的影响。本文的理论分析得出的结论是:就劳动的收入工资来说,短期内两个部门的工资都在提高,但长期内未被保护的高技术产品部门的工资反而会降低;就资本的报酬来说,短期内被保护部门机制品的资本报酬有所提高,而没有被保护部门的资本报酬反而会降低。因此,台湾提高进口关税的这种要素收入分配效应,不利于自己优势产业的发展,ECFA的实施有其经济学理念基础。

The raising up tariff by Taiwan to the products from Mainland of China will distort the factor income distribution pattern in that island. We use a general equilibrium model were an economy inputs two factors, i.e. capital and labor and produces two products, i.e. manufactures and high-technologies, to discuss the short run and long run effects on factor＇s income by the raising up tariff. We discover, the wage as the labor income in two production sectors is both rising up within the short run, but it is going down for an unprotected sector in a long run; the reward as the capital income in that protected sector is rising, but it is going down for another unprotected sector within a short run. So, the effects of factor income distribution comes from the imports tariff if adopted by Taiwan, will hurt the development of its advantaged industry. This is the theoretical foundation to promote FCFA.
