摘　　要：基于2003—2016年的城市面板数据,实证分析相关多样化、不相关多样化对城市服务业增长的影响。利用全国层面城市数据进行基准模型估计,分别从地区异质性、城市规模异质性、市场开放度差异方面进行更为深入细致的研究。结果显示:相关多样化、不相关多样化都对城市服务业增长存在显著的正向促进作用;而对于不同区域、不同规模和不同市场开放度的城市而言,相关多样化和不相关多样化对城市服务业增长的影响具有明显的差异。Based on China’s urban panel data from 2003 to 2016,this paper empirically analyses the impact of related variety and unrelated variety on the growth of urban service industry.The paper uses not only the city level data to estimate the benchmark model,but also makes further and detailed study respectively from the regional heterogeneity,urban scale heterogeneity and the differences of market openness.The paper finds that:both the related variety and unrelated variety significantly play positive role on promoting the growth of urban service industry;among the cities of different regions,different sizes and different market openness,the impact of the related variety and unrelated variety on the growth of urban service industry is obviously different.
