数字经济、生产要素结构和地区价值链地位攀升

Digital Economy,Structure of Production Factors and Upgrade of Value Chain Status

在数字经济下,数据要素的加入使生产要素结构发生变化,通过优化生产要素结构可能有助于地区价值链地位的提升。在理论分析的基础上,本文基于2011-2020年30个省市的面板数据系统探讨数字经济对地区价值链地位的影响效应,并通过构建生产要素结构测度指标体系,探究生产要素结构的中介效应、考察数据要素配置的门槛效应。研究发现:数字经济显著提升了地区价值链地位,其中对东部地区的作用尤为明显,这一结论在使用外生政策冲击克服内生影响和一系列稳健性检验后依然稳健。进一步研究发现,物质-劳动力要素结构已成为数字经济推动价值链地位攀升的重要渠道,数据要素暂未呈现显著正渠道效应。此外,数据要素配置在数字经济推动价值链地位攀升中呈显著U型门槛效应。由此,各地区需要借数字经济助力生产要素结构性改革,尤其是重点培育数据要素,以实现价值链地位的不断攀升。

In the digital economy,the addition of data elements causes changes in the structure of production factors,and optimizing the structure of production factors may help to enhance theposition of regional value chains.On the basis of theoretical analysis,this paper systematically discusses the impact of digital economy on regional value chain position based on the panel data of 30 provinces and cities from 2011 to 2020,and explores the mediation effect of production factor structure and the threshold effect of data factor allocation by constructing the measurement index system of production factor structure.The research results indicate that the digital economy has significantly improved the regional value chain position,with a particularly significant impact on the eastern region.This conclusion remains robust after using exogenous policy shocks to overcome endogenous effects and applying a series of robustness tests.Further research has found that the Material-Labor factor structure has become an important channel for the digital economy to drive the rise of value chain position,and data element configuration have not yet shown a significant positive channel effect.In addition,data element configuration exhibits a significant U-shaped threshold effect in the digital economy driving up the position of the value chain.As a result,all regions need to leverage the digital economy to assist in the structural reform of production factors,especially focusing on cultivating data elements to achieve the continuous rise of value chain status.
