摘要
文章基于2011—2022年中国省级面板数据,在测度数字经济发展与新型城镇化指数的基础上,分别利用沙普利值分解法、动态面板分位数回归模型和Sobel-Goodman中介效应模型研究数字经济发展对新型城镇化的贡献度、动态异质性影响及作用机制。结果表明:数字经济发展能显著促进新型城镇化,数字经济发展对新型城镇化的贡献度为26.34%;随着新型城镇化分位数的增加,数字经济发展对新型城镇化的影响呈现“倒U”型特征;虽然数字经济发展能通过产业结构升级、技术创新等渠道促进新型城镇化,但是要素市场化的渠道还不顺畅;整体来看,要素市场化、外商直接投资和固定资产投资对新型城镇化的促进作用还有提升空间。
Based on China’s provincial panel data from 2011 to 2022,this paper measures digital economy development and new-type urbanization index,uses Shapley value decomposition method,dynamic panel quantile regression model and So⁃bel-Goodman mediation effect model to study the contribution degree of digital economy development to the new-type urbaniza⁃tion,and its dynamic heterogeneity effect and mechanism of action on the new-type urbanization.The results are shown as fol⁃lows:Digital economy development can significantly promote new-type urbanization,and the contribution of digital economy de⁃velopment to new-type urbanization is 26.34%.With the increase of the quantile of new-type urbanization,the impact of digital economy development on new-type urbanization shows an inverted U-shaped trend.Digital economy development can promote new-type urbanization through industrial structure upgrading and technological innovation,but the channel of factor marketiza⁃tion is not smooth.As a whole,there is still room for improvement in the role of factor marketization,foreign direct investment and fixed asset investment in promoting new-type urbanization.
