Is Chinese Real GDP per Capita Broken Stationary Panel or Unit Root? New Evidence from Provincial-based Panel

A unit root in real output means that shocks to real output have permanent effects on the system. The combination of time and cross-section information reduces the lack of power that the time series based unit root when they are applied to the current available samples. It is well known that the erroneous omission of structural breaks in the series can lead to deceptive conclusions when performing the univariate integration order analysis. In the panel, each of the time series usually present structure changes. But little attention has been paid to structure breaks in panel data. In this paper, we use the panel unit root test allowed for multiple breaks developed by Carrion-i-Silvestre et al. (2005,CBL hereafter) to study whether the Chinese GDP per capita provincial-based panel dataset covering the period from 1952 to 2008 is a unit root or not. The evidence obtained that the Chinese GDP per capita is the trend stationarity panel, once breaks in the series are considered. The break points were associated with Chinese episodic events. So government polices is effective.
