数据要素对经济增长的影响——基于科学决策的中介效应分析

The Impact of Data Elements on Economic Growth—Analysis of Mediation Effect Based on Scientific Decision Making

在数字经济时代,数据要素作为数字化与智能化的基础,是促进经济增长的关键生产要素。数据要素通过辅助市场主体进行科学决策对经济增长产生重要影响。为论证数据要素对经济增长产生的作用,文章将数据要素引入经济增长理论模型,并进行数值模拟,从理论层面论证数据要素对经济增长产生的影响。同时,利用2013—2020年的中国284个地级市为面板数据,对数据要素对经济增长的影响及科学决策机制进行验证。结果表明随着数据要素投量的增加,公司利润、社会总利润随之增加,并收敛于某一上限,数据共享可以有效促进经济增长。数据要素发展水平显著提升了经济增长,但存在区域异质性,科学决策对经济增长起到中介作用。

In the era of digital economy,data elements which play the role of the basis of digitization and intelligence are key production factors to promote economic growth.Data elements affect economic growth through assisting market players in scientific decision-making.To illustrate the impact of data elements on economic growth theoretically,this paper introduces data elements into the theoretical model of economic growth and makes numerical simulation.In addition,it applies the panel data of 284 national prefecture-level cities and above from 2013 to 2020 to verify the impact of data elements on economic growth and scientific decision-making mechanisms.The results show that the increase of data element investment has witnessed the spurt of the company’s profit and social total profit which will stop at a certain limit.Data sharing can effectively promote the economic growth.The development level of data elements has significantly improved economic growth.However,there exists regional heterogeneity.At the same time,scientific decision-making plays an intermediary role in economic growth.
