相關(guān)多樣化、不相關(guān)多樣化與城市服務(wù)業(yè)增長

摘要： 基于2003—2016年的城市面板數(shù)據(jù),實證分析相關(guān)多樣化、不相關(guān)多樣化對城市服務(wù)業(yè)增長的影響。利用全國層面城市數(shù)據(jù)進(jìn)行基準(zhǔn)模型估計,分別從地區(qū)異質(zhì)性、城市規(guī)模異質(zhì)性、市場開放度差異方面進(jìn)行更為深入細(xì)致的研究。結(jié)果顯示:相關(guān)多樣化、不相關(guān)多樣化都對城市服務(wù)業(yè)增長存在顯著的正向促進(jìn)作用;而對于不同區(qū)域、不同規(guī)模和不同市場開放度的城市而言,相關(guān)多樣化和不相關(guān)多樣化對城市服務(wù)業(yè)增長的影響具有明顯的差異。
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.
