我国服务业结构效应与空间效应的区位变迁——来自我国八大经济区服务业的经验证据

Structural Effect of Chinese Service Industry and Regional Transformation of Spatial Effect——Experience Evidence of Service Industry from Eight Economic Regions

利用偏离份额模型测度我国八大区服务业的全国同步增长效应、结构效应和竞争效应,并引入同位变化和空间依赖模型对竞争效应进行分解,研究结果表明:我国各区域服务业增长存在着显著的差异性;我国不同区域服务业结构效应和空间效应存在较大的差异性;八大经济区服务业存在结构优势的子产业占83%;西北地区服务业表现出明显的空间竞争劣势;结构效应、区位效应和空间效应对区域服务业增长贡献的方向并非完全一致,我国区位效应对区域服务业增长的影响明显低于结构效应的影响,服务业区域专业化和地理集中度呈现非同步性。

The deviation portion model has been adopted to measure the simultaneous growth effect, structural effect and competitive effect in the eight service regions in China and the simultaneous change and spatial dependence model are introduced to analyze competitive effect. The result shows that there are great differences in the growth of the service industry in China; there are differences in the structural effect and spatial effect; the sub-industry with structural superiority accounts for 83%; there is obvious inferiority in the service industry in northwest region; structural effect, regional effect and spatial effect contribute differently to the growth of the service industry in these regions with the contribution of regional effect obviously lower than that of the structural effect and the specialization and regional concentration degree developing differently.
