摘　　要：以我国不同区位的6个城市群为研究对象,先运用综合评价法分析城市群在2011—2020年扩散效应水平的变化,再利用障碍因子诊断法判断影响城市群发挥扩散效应的障碍因子,得到结论:①6个城市群的扩散效应水平在研究期内呈上升趋势。②东部沿海3个城市群的扩散效应水平得分较高,中部的成渝城市群和长江中游城市群扩散效应水平得分相当,西部的关中平原城市群扩散效应水平得分相对较低。③扩散基础和扩散环境是制约城市群发挥扩散效应的主要因素,其中专利授权数和外商投资企业数是重点因子。结果表明创新和开发可以为技术更新和转移、市场竞争和合作等方面提供更多的机会和动力,从而促进城市群发挥扩散效应。This paper takes six city clusters in different locations of China as the research object,analyzes the changes of the diffusion effect level of city clusters during 2011-2020 by using the comprehensive evaluation method,and then uses the obstacle factor diagnostic method to judge the obstacle factors affecting city clusters to play the diffusion effect,and obtains the following conclusions:①The diffusion effect level of six city clusters shows an upward trend in the research period.②The diffusion effect level of three city clusters on the east coast scores high;the Chengdu-Chongqing city cluster and the city cluster in the middle reaches of the Yangtze River in the center scores comparable diffusion effect level;the Guanzhong Plain city cluster in the west scores relatively low diffusion effect level.③Diffusion foundation and diffusion environment are the main factors that restrict the city clusters from exerting diffusion effect,among which the number of patents authorized and the number of foreign-invested enterprises are the key factors.The results show that innovation and development can provide more opportunities and motivation for technology renewal and transfer,market competition and cooperation,etc.,thus facilitating the city clusters to realize the diffusion effect.
