摘要: 基于2014年开始陆续建立数据交易平台的准自然实验,采用2011—2018年中国277个城市面板数据,构建双重差分模型考察了以数据交易平台建设为表征的数据要素市场建设对城市数字经济发展的影响。研究发现:数据要素市场建设显著促进了城市数字经济发展,在进行平行趋势检验、反事实检验及工具变量法等一系列稳健性检验后,结论依然显著,且短期内数据要素市场建设扩大了地区间数字鸿沟。作用机制分析表明,数据要素市场建设通过促进制造业和服务业融合发展、提升资本与劳动配置效率显著推动了城市数字经济发展。进一步的异质性分析发现,数据要素市场建设对数字经济发展的影响在数字基础设施、创新能力、政府干预程度方面存在显著的异质性。

Abstract: This paper conducts a quasi-natural experiment based on the data trading platforms successively built since 2014. By making use of the panel data from 277 cities in China from 2011 to 2018, it constructs a difference-in-difference model to examine the influence of data element market construction characterized by the construction of data trading platforms on the development of urban digital economy. The findings show that the construction of the data element market has significantly promoted the development of urban digital economy, and that this conclusion is still significant after a series of robustness tests, such as parallel trend test, counterfactual test, and instrumental variable method, etc. In a short term, the construction of data element market has expanded the inter-regional digital gap. The mechanism analysis indicates that the construction of data element market has significantly promoted the development of urban digital economy through promoting the integrated development of the manufacturing industry and the service industries and improving the efficiency of capital and labor allocation. Further heterogeneity analysis reveals that the influence of the construction of data element market on the digital economic development has significant heterogeneity in terms of digital infrastructure, innovation capabilities, and government intervention.

Key words: data element market, digital economy, data trading platform, difference-in-difference
