采用相对价格法计算珠三角地区9城市2002—2010年市场一体化指数,在构建市场一体化指数数据库的基础上,研究了珠三角地区市场一体化的经济增长效应。实证分析发现:其一,采用两种方法都为“非对称溢出效应”的存在提供了直接的经验依据;其二,对于大多数样本,市场非一体化阻碍经济增长。模型和实证有助于理解不同发展水平的地方政府对待市场一体化的行为动机的复杂性,为政府进一步推进市场一体化和协调区域发展提供参考。
Using the relative price method to calculate the market integration index of 9 cities in the Pearl River Delta from 2002 to 2010, this paper studies the economic growth effect of the market integration in the Pearl River Delta based on the construction of the market integration index database. The empirical analysis shows that firstly, the adoption of both methods provides a direct empirical basis for the existence of the asymmetric spillover effect. Second, for most samples, the non-integrated market hinders economic growth. The model and empirical study can help to understand the complexity of local government’s behavior motivation towards market integration at different development levels and provide reference for the government to further promote market integration and coordinate regional development.
