我国省际经济增长路径的收敛性检验

Convergence Testing for China's Interprovincial Economic Growth

提出了强σ-收敛和弱σ-收敛等新的σ-收敛概念,并选择实际人均GDP自然对数标准差和实际人均GDP变异系数两个指标来度量σ-收敛性,运用DF-GLS单位根检验方法和ARFIMA模型,检验了强σ-收敛和弱σ-收敛在我国全国范围内以及东、中、西部地区的存在性.检验结论显示:所研究的四个区域都不存在强σ-收敛特征,但均表现出显著的弱σ-收敛特征.

Two new σ-convergence conceptions such as strong σ- convergence and weak a - convergence were put for- ward, and σ-convergence was measured by two indicators including natural logarithm standard deviation of real per capita GDP and coefficient of variation of real per capita GDP. By using DF-GLS unit root test method and ARFIMA model, the existence of strongσ- convergence and weak a - convergence in China, and in the eastern, central and western regions were tested. The results indicate that significant weak σ- convergence instead of strong σ-convergence exists among these regions.
