技术要素空间联系时空演化及其对经济增长的影响研究——基于中国省域数据

Research on the Temporal-Spatial Evolution of the Spatial Linkage of Technology Factors and Its Impact on Economic Growth:Based on China's Provincial Data

以我国31个省域为分析样本,运用引力模型、空间趋势面分析技术要素空间联系的时空演化特征,进一步构建空间计量面板模型实证揭示技术要素空间联系对区域经济增长的空间影响效应。结果表明:我国各省域技术要素空间联系水平在不断提高但区域分布差异明显,从“飘带”型布局逐渐演化为反“卜”字型、横“土”字型空间布局,且整体呈现“东高西低,南稳北降”的空间分异趋势;技术要素空间联系对区域经济增长有显著的正向影响,可通过直接效应、间接效应和总效应促进区域经济增长,对区域经济增长的空间集聚作用要大于其空间扩散作用。

This paper explores the spatial-temporal evolutionary characteristics of the spatial linkage of technology factors in 31 provinces in China using gravity model and spatial trend surface analysis,and further constructs the spatial panel model to investigate the specific effect of spatial linkage of technology factors on regional economic growth by using spatial econometric.The conclusions are as follows:the level of spatial linkage of technology factors in various provinces in China are constantly increasing and have obvious regional differences,their level spatial layout have gradually evolved from"streamer"to anti"bo"type to horizontal"tu"type,and the overall spatial differentiation trend is"high in the east,low in the west,stable in the south and down in the north".The spatial linkage of technology factor has a significant positive impact on regional economic growth,it actively promotes regional economic growth by the direct effect,indirect effect and total effect.And the spatial agglomeration effect on regional economic growth is greater than its spatial diffusion effect.
