贸易数字化对实体经济产生了怎样的影响

What Impact Does Trade Digitization Have on the Real Economy

贸易数字化作为经济增长的新动力,是推动实体经济高质量发展的重要引擎。本文利用2013~2019年285个城市的面板数据,运用熵权TOPSIS法测算了城市的贸易数字化发展水平,并采用空间计量模型研究贸易数字化对城市实体经济的影响。研究结果表明:中国城市贸易数字化正在高速发展,呈现出逐年上升的趋势;贸易数字化和实体经济表现出显著的空间相关性;贸易数字化能够推动本城市实体经济的发展,并对周边城市实体经济的发展也产生正向的空间溢出效应;贸易数字化还会以创新研发和消费水平为中介变量进一步促进实体经济的发展;贸易数字化对东、西部城市以及“胡焕庸线”西侧地区实体经济发展的促进作用更为明显;贸易数字化对特大城市的影响较小,对其他城市的溢出效用较大;最后为推动贸易数字化和实体经济发展提出了三点政策建议。

As a new engine of economic growth,trade digitization is an important way to promote the development of real economy.Exploiting the panel data of 285 cities in China from 2013 to 2019,this paper uses the entropy weighted TOPSIS method to calculate the trade digitization level of cities,and employ the spatial econometric model to analyze the impact of trade digitization level on urban real economy.Our main conclusions are as follows:There is a significant spatial correlation between trade digitization and real economy;Trade digitization can significantly promote the development level of real economy and have a positive spillover effect on the development of real economy in adjacent areas;Innovative and consumption play important roles in promoting real economy for trade digitization;Heterogeneity analysis shows that trade digitization plays a more significant role in promoting the development of real economy in eastern and western cities and the west of Hu Huanyong line;The level of trade digitization can significantly promote the development of real economy in cities of different sizes,especially in large,medium and small cities;Finally,three policy suggestions are proposed to promote the development of trade digitization and real economy.
