交通网络密度、劳动力水平与商贸流通经济关系研究

On the Relationship Between Traffic Network Density,Labor Level and Commercial Circulation Economy

文章基于2009—2018年我国省级面板数据,利用一般线性面板模型与门槛效应模型实证分析了交通网络密度、劳动力水平对商贸流通经济的影响作用。研究结果表明:交通网络密度对商贸流通经济的影响存在显著的线性促进作用,而劳动力水平的影响作用并不显著;在异质性劳动力水平约束下,交通网络密度对商贸流通经济的影响存在着非线性门槛特征,随着劳动力水平的提升,交通网络密度的积极作用在逐渐增强。因此,要不断完善全国交通网络系统,持续优化劳动力供给结构,扩大劳动力水平,发挥交通设施对商贸流通经济的正向作用。

Based on China’s provincial panel data from 2009 to 2018,this paper empirically analyzes the impact of traffic network density and labor level on trade circulation economy by using general linear panel model and threshold effect model.The results show that the traffic network density has a significant linear promoting effect on the trade circulation economy,while the effect of labor level is not significant.Under the constraint of heterogeneous labor level,the impact of traffic network density on commercial circulation economy has nonlinear threshold characteristics.With the improvement of labor level,the positive role of traffic network density is gradually increasing.Therefore,it is necessary to continuously improve the national transportation network system,continuously optimize the labor supply structure,expand the labor level,and give full play to the positive role of transportation facilities on the commercial circulation economy.
