方言距离与城市间产业结构趋同

Dialectal Distance and Urban Industrial Structure Convergence

本文研究方言距离、知识流动与中国城市间产业结构合意性趋同之间的关系。基于工业企业数据库和海关数据库的研究发现,中国城市之间的方言距离阻碍了知识的跨地区流动,从而影响了产业结构的合意性趋同。具体而言,在静态层面,控制地理距离、是否相邻、要素禀赋差异、人均GDP差异和人口规模差异等一系列因素后,方言距离对城市之间的产业结构相似度仍然有统计上和经济上显著的负面影响。在动态层面,当与本城市方言距离越小的城市在某一产业上有比较优势时,本城市未来进入该产业以及在该产业建立比较优势的概率越大。

This paper examines the relationship between dialectal distance,knowledge spillover and industrial structure convergence in Chinese cities.Based on the China Industrial Enterprises Database and China Customs Database,it is found that the dialectal distance between Chinese cities hinders the cross-regional knowledge diffusion,thereby affecting the cross-city convergence of the urban industrial structure.At the static level,after controlling a number of variables,such as geographic distance,contiguity,difference in per capita GDP,population size and factor endowments,dialectal distance still has a statistically and economically significant negative effect on the industrial structure similarity.At the dynamic level,the likelihood of a city entering a particular industry and establishing a comparative advantage in this industry is significantly higher when other cities with a smaller dialectal distance have a comparative advantage in this industry.
