通过光滑结构变化和非线性调整的单位根检验方法,检验1952-2010年间我国25省市相对北京市的实际人均产出收敛性特征,并估算其非对称收敛速度。实证结果表明,一方面各相对产出序列均具有非线性特征,且都只有一个重大事件影响其产出差异的均值;另一方面,研究显示其中18个地区经济增长表现为随机收敛,且收敛速度具有非对称性,外在冲击对大部分地区的相对产出效果表现出了较强的粘持性。 The unit root test of smooth structural change and non-linear adjustment verifies the convergence of output per capita in 25 provinces in China from 1952 to 2010 and estimates the asymmetric convergence rate. The empirical results show that on the one hand, all the relative output series have nonlinear characteristics, and only one major event affects the average value of their output differences; on the other hand, the research shows that the economic growth in 18 of them shows random convergence and convergence The speed has the asymmetry, the external impact on the relative output effect in most areas showed the stronger adhesion.
