技术差距、资本深化与中国区域经济差距——来自面板数据VAR模型的证据

【摘要】：中国当前显著的区域经济差异是由于投资的差异还是由于技术的差异?这个问题对于制定区域经济政策,实现区域协调发展十分重要。本文运用DEA模型对我国各个省域的技术效率进行了分析,发现各省域间存在显著的技术差异,且这一差异呈现出先增大后减小的趋势。为检验技术差异与经济差距间的相关关系,我们进一步引入资本存量差异建立了面板数据VAR模型,并进行了脉冲响应和方差分解分析。结果表明,实际经济差距仅来源于资本深化,但人均产出差距与技术差异间呈现出显著的正相关关系。技术进步对GDP的拉动作用正在占据越来越大的比重,技术差异是经济差距的又一重要源泉,因而单纯强调资本投入的区域发展战略并不足以实现区域经济收敛。
[Abstract]:Is the significant regional economic difference in China due to the difference in investment or the difference in technology? This problem is very important for the formulation of regional economic policy and the realization of regional coordinated development. In this paper, the DEA model is used to analyze the technical efficiency of various provinces in China. It is found that there are significant technical differences among provinces, and this difference shows a trend of first increasing and then decreasing. In order to test the correlation between technology difference and economic gap, we further introduce the capital stock difference to establish a panel data VAR model, and carry out impulse response and variance decomposition analysis. The results show that the actual economic gap is only derived from capital deepening, but there is a significant positive correlation between the per capita output gap and technological differences. The pulling effect of technological progress on GDP is occupying an increasingly large proportion, and technological difference is another important source of economic disparity. Therefore, the regional development strategy that emphasizes the capital input is not enough to realize the regional economic convergence.
