基于边界效应模型的我国市场一体化问题研究

改革开放使我国走向市场经济道路并取得了一系列的成就，但是我国的市场一体化程度却遭到了很多质疑。许多学者从不同角度对我国市场一体化程度进行了研究，但由于研究的方法不同，得到的结果也不尽相同。本文利用Head和Mayer（2002）修正后的边界效应模型和区域间投入产出表的数据对我国市场一体化程度进行了实证研究。结果表明。我国确实存在一定程度的市场分割，特别是农业、纺织业、金属制品业和非金属矿物制品业等关系到地方就业与税收的部门市场分割比较严重。

Research on China's Domestic Market Integration: Basing on the Border Effect Model

The policy of reforming and opening has brought a lot of success in China, therefore China has stepped into the road of market economy. But the Chinese market integration has met with a lot of doubts. Many scholars have studied on the level of China＇ s domestic market integration from different perspectives; the results varied for the difference in their research methods. In this paper, we empirically researched on the degree of China＇ s domestic market integration applying the border effect model amended by Head and Mayer in 2002 and the data from the provincial input-output tables, and found that there indeed existed market fragmentation in China, especially in the sectors of agriculture, textile, metal products and nonmetal products.
