中国区域相对价格水平收敛性实证研究

应用第一代、二代面板数据单位根检验方法对我国省域间相对价格水平收敛性进行实证研究,进而为我国促进区域市场整合提供政策建议。研究结果发现:全国范围内存在相对价格水平收敛;进一步将全国分成东、中、西三大区域,结果发现东部与中部相对价格水平收敛依然可以成立,但西部地区仍然存在一定程度的市场分割;在收敛速度方面,东、中部与全国保持比较一致;CPI各分类商品价格指数以食品类收敛速度最快,而交通、通讯价格指数最慢。

Empirical Study on Convergence of China's Regional Relative Price

For the purpose of providing the government with policy advices to promote regional market integration, this paper applies both the first generation and second generation of panel unit root tests to make an empirical study of the relative price convergence across China＇ s provinces. The results find that there exists price convergence in the whole country. Further, having classified the provinces as three main regions including east area, middle area and west area, the results still support the price convergence both in east and middle area. Nevertheless, there exists market segmentation in the west area. In terms of the convergence speed, the east and middle area keep fairly consistent with the whole country,and as far as the specific goods price index is concerned, the food price converges the most quickly while the transportation price converges the most slowly.
