数字经济、科技服务业的协同发展及区域协同效应

The synergistic development of digital economy and technology service industry and their synergistic effects on regional economy

数字经济为新一轮产业变革和经济增长提供重要动力,科技服务业是优化产业结构和提升经济效率的重要新兴产业,数字经济与科技服务业(简称“二者”)的协同发展现状及协同效应如何?本文采用熵权—Topsis法、耦合协调模型对我国30个省份的数字经济、科技服务业的演化及二者协同演化特征进行分析并采用双向固定效应模型、门限效应模型实证检验二者协同发展对我国区域经济效率的影响。研究发现:2012—2019年,30个省份数字经济、科技服务业发展指数上升趋势明显,在空间上呈现出明显异质性,东部地区高于中西部、东北地区;二者协同水平持续提升,2012年位于失调落后区间的省份为22个,2019年减少至10个;二者协同状况呈现为“高高集聚”与“低低集聚”特征;二者协同发展正向影响区域工业劳动生产率、工业纯技术效率和GDP增长率,而对区域投资效率带来负向影响。本研究对我国评估区域数字经济、科技服务业、二者协同发展现状,优化各区域数字经济发展规划与政策、提升科技服务水平具有借鉴意义。

Digital economy provides an important driving force for a new round of industrial transformation and economic growth,and the science and technology service industry is an important emerging industry to optimize the industrial structure and improve economic efficiency.What is the synergistic status and effect of digital economy and the science and technology service industry?To this end,the synergistic development mechanism of the digital economy and the science and technology service industry was analyzed with the Entropy right-Topsis method and the coupling coordination model to study the evolution of the digital economy,the science and technology service industry and their synergy evolution characteristics in 30 provincial-level regions of China,while the two-way fixed effect model and gating effect model were used to empirically test the influence of the synergistic development on the regional economic efficiency in China.The research findings were as follows:from 2012 to 2019,the development index of the digital economy and the science and technology service industry in 30 provincial-level regions showed an obvious rising trend,presented a distinct heterogeneity in space,and the eastern region is higher than that of the central and western regions and the northeast regions;the synergistic level between the digital economy and the science and technology service industry continues to improve.In 2012,the number of 22 provincial-level regions were located in the lose balance and drop behind range,and the number decreased to 10 in 2019,it is characterized by"high and high agglomeration"and"low and low agglomeration"in the geographical distribution of the digital economy and the science and technology service industry.The synergistic development of the digital economy and the science and technology service industry positively affects the regional industrial labor productivity,industrial pure technology efficiency and GDP growth rate,and brings a negative impact on the regional investment efficiency.This paper explored the spatial and temporal evolution characteristics,synergistic mechanism and influence effect of the synergistic development of the digital economy and the science and technology service industry from the perspective of industrial correlation,and it will enrich the relevant innovation theory research,and grasp the situation of regional digital economy,science and technology service industry,the synergistic development of the two,thus optimizing the development planning and policies of the digital economy in various regions and improving the level of scientific and technological services has a positive promoting effect.
