高技术制造业与高技术服务业协同集聚的经济增长效应

基于中国省级面板数据，利用空间面板模型和面板门槛模型，探究高技术制造业与高技术服务业协同集聚的经济增长效应。结果表明：区域间产业集聚特征差异显著，高协同集聚主要集中在东部沿海地区，低协同集聚主要集中在西部地区。经济增长水平、高技术制造业与高技术服务业协同集聚水平均具有显著空间正相关性，二者协同集聚有助于促进区域经济增长。协同集聚的经济增长效应存在双重门槛，当高技术制造业集聚度和高技术服务业集聚度均介于第一、二门槛之间时，产业协同集聚的经济增长效应最强。仅少部分省域两产业集聚度介于第一二门槛之间，能够有效发挥协同集聚对经济增长的推动作用。

The Economic Growth Effect of the High-tech Manufacturing Industry and High-Tech Service Industry Co-Agglomeration

Based on the provincial panel data in China, this paper apply the spatial panel model and the panel threshold model to explore the economic growth effect of high-tech manufacturing clustering and high-tech service clustering. The results show that there are significant differences in industrial agglomeration characteristics between regions. High-synergy agglomerations are mainly concentrated in the eastern coastal areas, and low-synergy agglomerations are mainly concentrated in the west. The level of economic growth, thelevel of coordinated agglomeration of high-tech manufacturing and high-tech service industries have a significant spatial positive correlation, and the coordinated agglomeration of the two helps to promote regional economic growth. There are double thresholds for the economic growth effect of coordinated agglomeration. When the agglomeration degree of high-tech manufacturing and high-tech service industry are between the first and second thresholds, the economic growth effect of industrial agglomeration is the best. Only a small number of provinces are between the first and second thresholds for the concentration of two industries, which can effectively play a role in promoting economic growth by coordinated agglomeration.
