全球化经济进程以及我国加入世贸组织推动我国对外贸易快速发展,经济高速发展带来对资源的消耗日益增长,使得进口产品量进一步扩大,国内经济系统受进口产品的影响加重.然而国际市场价格的波动,以及我国进口关税的变化,导致了进口产品价格波动.由于经济系统中各个产业部门相互关联,进口产品比例和进口产品价格的波动必然对国内各个产业的产品价格产生相应的波及效应.本文应用投入产出的分析方法,构建进口产品价格影响模型,应用1997年和2002年投入产出表,定量研究了进口产品价格的变动对各个产业部门价格变动的波及效应,并进行了进口价格变动的模拟.
The globalization of the economy and China’s accession to the WTO have promoted the rapid development of China’s foreign trade and the rapid consumption of resources brought by the rapid economic development has led to the further expansion of the volume of imported products and the aggravating impact of the domestic economic system on the imported products. However, the international market prices The fluctuation of import tariffs and the change of import tariffs in our country lead to the fluctuation of the prices of imported products.Because the various industrial sectors in the economic system are interrelated, the fluctuation of the prices of imported products and imported products inevitably has a corresponding ripple effect on the prices of various domestic products. Applying the method of input-output analysis, this paper constructs the model of the impact of the price of imported products. Using the input-output tables of 1997 and 2002, we quantitatively study the effect of the price changes of imported products on the price fluctuations of various industrial sectors and carry out the import price changes Simulation.
