分权体制下的市场分割与经济增长关系实证研究

Empirical Analysis about the Relationship of Market Segmentation and Economic Growth Under the Decentralized System

文章利用1996—2008年的商品零售价格指数,测度了国内商品市场的分割度。从财政分权带来市场分割的角度,运用1996—2008年我国分省面板数据,考察了影响市场分割程度的因素。研究发现,财政分权、国有化程度、出口、外商直接投资会加剧市场分割,而地区之间的技术差异、进口、投资市场化会促进国内市场整合。鉴于中国持续存在的省际市场分割现象,研究了市场分割对于省级经济增长的效应,发现市场分割有利于本地经济增长,并且对经济增长有倒U型的影响。进一步对我国市场分割、财政分权和经济增长的关系进行分析,发现市场分割会加强财政分权的经济增长效应。

This paper measures the degree of domestic goods market segmentation with the retail price index from 1996 to 2008. Thus, this paper studies the factors that affect the degree of market segmentation from the view of that the market segmentation comes from fiscal decentralization based on the provincial panel data from 1996 to 2008 in China. The study found that the fiscal decentralization, nationalization, exports and foreign direct investments will exacerbate market segmentation, and the technical differences between the regions, imports, investment market-oriented will promote the integration of the domestic market. And this paper studies the effects of market segmentation to provincial economic growth from the view of the persistence phenomenon of provincial market segmentation in China. And the study discovers that the market segmentation is conducive to the growth of the local economy, and there is an inverted U-shaped impact on the economic growth. This paper further analyzes the relationship among the Chinese fiscal mar- ket segmentation, fiscal decentralization and economic growth. The analysis finds that the market segmen- tation will strengthen the economic growth effects of the fiscal decentralization.
