高技术服务业集聚专业化、多样化与城市经济增长质量

The Agglomeration Specialization and Diversification of High-Tech Service Industry and the Quality of Urban Economic Growth

为探究高技术服务业集聚对城市经济增长质量的影响机制,选用中国283个地级及以上城市2003-2015年的面板数据进行回归分析。研究发现,具有劳动力蓄水池效应和中间品共享效应的高技术服务业专业化集聚更有利于促进城市经济增长质量的提高,而多样化集聚的作用效果为负且不显著;高技术服务业集聚对城市经济增长质量的影响存在显著的区域性差异和行业差异,东部地区的专业化集聚效应明显优于中部和西部地区,城市经济增长质量主要受信息服务业和软件业专业化集聚的影响,而科技服务业专业化集聚的影响不明显。进一步研究发现,随着城市规模扩大,提高高技术服务业集聚多样化和专业化水平将促进城市经济高质量增长,而与小城市优势条件更加吻合的高技术服务业集聚模式是专业化集聚。

To investigate the influence mechanism of high-tech service industry agglomeration on the quality of urban economic growth, panel data of 283 municipal-level and above cities in China from 2003 to 2015 were selected for regression analysis. The results show that the specialized agglomeration that possesses labor pool effect and intermediate goods sharing effect is more conducive to promoting the quality of urban economic growth, while the effect of its diversified agglomeration is negative and insignificant. There are significant regional and industrial effect differences in their promotion quality, and the specialized agglomeration effect in the eastern regions is significantly better than that in the central and western regions. The quality of urban economic growth is mainly influenced by the specialized agglomeration of information service industry and software industry, while that of sci-tech service industry is not obvious. Further research finds that with the expansion of city scale, increasing the diversification and specialization of high-tech service industry agglomeration will promote the high-quality development of urban economy. Specialized agglomeration is an agglomeration model that is more consistent with the advantageous conditions of small cities.
