The Provincial Disparity of Economic Growth and Dynamic Process in China——Based on Panel Data of 31 Provinces and Oaxaca-Blinder Model
将中国31个省份按1993-2012年经济增长速度分为快、中、慢三类，用Oaxaca-Blinder模型分解差异因素，发现政府政策和市场化是主因，但落后地区过度依赖政府投资，易陷入“梅佐乔诺陷阱”。
Different from the traditional grouping way according to spatial distribution when researching the regional disparity of economic growth, starting from the Chinese actual situation about the dynamic change of the gap of provincial economic growth,We divided 31 provinces into three types of rapid growth, medium growth and slow growth in stages during 1993~2012. Then through comparative analysis between fast areas and slow growth areas, we tried to explore the law of provincial economic growth and its main influencing factors. By using Oaxaca- Blinder model we decomposed the factor influencing the provincial disparity of economic growth, and calculated the contribution rate of these factors. The results show that government policy and marketization are the main factors that influence the provincial difference,but the narrow of regional gap is over dependent on government investment. Because its influence on economic grouth continues to be weakened, the backward areas are more likely to fall into Mezzogiorno Trap once the policy is difficult to continue. therefore, it may be the effective way to narrow regional disparity of the backward area by cultivating their own development potential and deepening market reform.
