摘要 利用2007—2019年127个地级市的数据,系统检验了中心城市科技创新对城市群协调发展的影响机制,并讨论了收入房价比对二者关系的调节作用。研究发现:第一,中心城市科技创新水平的提高不仅显著促进了城市群协调发展,还加快了外围城市经济增长收敛,并在不同地区和不同发展阶段的城市群表现出明显的异质性。第二,中心城市科技创新通过深化产业分工促进城市群协调发展。第三,收入房价比能够调节中心城市科技创新与城市群协调发展之间的关系,但调节效果存在区域异质性,仅在中部地区显著增强了中心城市科技创新对城市群协调发展的促进作用,对东部和西部地区没有明显的调节作用。研究结论不仅丰富了中心城市科技创新影响城市群协调发展的理论研究,且在提高收入房价比方面提供了政策启示。

Abstract： Based on the data of listed companies in 127 prefecture-level cities from 2007 to 2019, this paper systematically examines the influence mechanism of technological innovation in central cities on the coordinated development of urban agglomerations, and discusses the moderating effect of housing-price to income ratio. There are following findings: Firstly, the improvement of technological innovation level in central cities not only significantly promotes the coordinated development of urban agglomerations, but also accelerates the convergence of economic growth in peripheral cities, and shows obvious heterogeneity in urban agglomerations in different regions and development stages; Secondly, technological innovation in central cities promotes coordinated development of urban agglomerations through deepening industrial division of labor; Thirdly, the income to housing price ratio can regulate the relationship between technological innovation in central cities and the coordinated development of urban agglomerations, but the regulatory effect has regional heterogeneity. Only in the central region, it significantly enhances the promoting effect of technological innovation in central cities on the coordinated development of urban agglomerations, and has no significant regulatory effect on the eastern and western regions. The research findings not only enrich the theoretical research on the impact of technological innovation in central cities on the coordinated development of urban agglomerations, but also provide policy insights in improving the housing-price to income ratio.
Keywords： Technological Innovation in Central Cities   Coordinated Development of Urban Agglomerations   Housing-Price to Income Ratio   Industrial Division of Labor   Moderating Effect
