本地偏好、边界效应与市场一体化——基于中国地区间增值税流动数据的实证研究

Home Biases,Border Effects and Market Integration:An Empirical Study Based on Inter-provincial VAT Survey

本文采用2003--2005年中国省际产品贸易及缴纳增值税的数据，在边界效应模型中对省际贸易的本地偏好程度进行了实证检验。本文发现：在各种模型设定下，中国省际产品贸易确实存在明显的本地偏好；在控制了经济规模、对外贸易、行政区划、临近效应、双边及多边贸易壁垒等因素之后，历年的省际边界效应大约在4—6之间；2003--2005年，省际边界效应没有出现一致的变化趋势。本文的结果表明中国国内产品市场的一体化已具备较高的水平。

This paper uses goods trade data between any two provinces of China in 2003--2005 to examine the home bias of trade and domestic integration of product markets in China. Within the framework of the border effect model, our empirical tests show that interprovincial border effects do matter in China and there are home biases in inter-provincial trade. After output, international trade, government behavior, bilateral and multilateral trade barriers are controlled, border effects in our empirical models are mostly between 4 and 6, and there is no time trend during the study period. The conclusion is that domestic product market integration is not as bad as other researchers have found
