中国地区经济σ-收敛的空间计量实证分析

A Spatial investigation of σ-convergence in China

本文采用空间经济计量方法,使用25年人均GDP数据研究中国28个省区经济发展的σ-收敛情况。研究结果表明,考虑到省区间相关性,特别是经济间的相关性后,可显著纠正采用传统方法进行σ-收敛研究产生的误差。修正后的σ-收敛值表明,随着中国经济发展,尤其是近几年省区间经济表现出σ-收敛的趋势。

Using techniques of spatial econometrics, we study the σ-convergence of real per capita GDP across 28 provinces and cities rolling over 25 years in China. It is evident that the spatial dependence across regions is strong enough to distort the traditional measure of ; - convergence- The corrected e - convergence in China indicates a lower level of dispersion in the economic development process with a promising trend of convergence in the recent years.
