本文通过引入空间联系将市场分割对经济增长的影响分为当期效应和回响效应,当期效应和回响效应又分为直接效应和溢出效应,因此,市场分割对经济增长总效应可以分解为直接效应和间接效应。在此基础上,利用空间Durbin面板模型实证检验了省际市场分割对经济增长的影响,研究发现,1986-2009年和1994-2009年市场分割对经济增长的当期直接效应和溢出效应都为负,直接效应、间接效应和总效应都为负,但是1986-1993年间,市场分割对经济增长的当期直接效应和溢出效应都为正,直接效应、间接效应和总效应也都为正。
This paper divides the impact of market segmentation on economic growth into two parts: current effect and reverberation effect by introducing spatial connection. The current effect and reverberation effect are divided into direct effect and spillover effect. Therefore, the total effect of market segmentation on economic growth can be decomposed into direct effect and Indirect effects. On this basis, the spatial Durbin panel model is used to empirically test the effect of market segmentation on economic growth. The results show that the direct and spillover effect of market segmentation on economic growth in 1986-2009 and 1994-2009 is negative , The direct effect, the indirect effect and the total effect are both negative. However, both the direct effect and the spillover effect of market segmentation on economic growth are positive during 1986-1993, and both the direct effect, indirect effect and total effect are positive.
