通过拓展门限套利模型,为各类地区特征因素对我国地区间相对价格水平收敛性产生不同影响的假说提供了理论支持;同时,在实证研究中测算了新数据,并综合利用第一、二代面板单位根检验方法,以尽量减少检验方法不适当所带来的统计检验偏误。按地区特征分组后,对我国地区间相对价格水平在1995-2010年样本段收敛性差异的检验显示,国内地区间相对价格水平倾向于在较开放和较富裕的地区间收敛,且表现出有条件的“类俱乐部收敛”特性,而按同一特征的不同状态分组后会出现多个收敛状态。
By extending the threshold arbitrage model, the theoretical support is provided for the hypothesis that the characteristics of various regions affect the convergence of relative price levels in different regions in China. Meanwhile, new data are estimated in the empirical study and the first and second generation Panel unit root test method to minimize the statistical test error caused by improper test methods. According to the regional characteristics, the test of the convergence of the relative price level in China from 1995 to 2010 shows that the relative price level in the Mainland tends to converge in the more open and richer regions, and shows that there are Conditions “class club convergence ” characteristics, and according to the same characteristics of different states will appear after the convergence of multiple states.
