数字全球价值链嵌入对企业劳动收入份额的影响

The Impact of Digital Global Value Chain Embeddedness on Firms'Share of Labor Income

选取2012—2022年中国A股上市公司数据,构建多种计量模型,考察数字全球价值链嵌入对企业劳动收入份额的影响与作用机制。结果发现:数字全球价值链嵌入能够显著推动企业劳动收入份额提升,并且可通过降低企业外部交易成本对其产生间接影响。数字全球价值链嵌入在不同数字经济发展门槛值下,对企业劳动收入份额的促进作用呈现边际递增的非线性特征。数字全球价值链嵌入对成熟期企业、制造业企业劳动收入份额的促进作用更强。据此,提出提高数字全球价值链嵌入水平、加快企业数字化转型、推进数字经济高质量发展的建议,为提升企业劳动收入份额提供理论支撑。

Based on the data of China's A-share listed companies from 2012 to 2022,this paper constructs a variety of econometric models to investigate the impact and mechanism of digital global value chain embedment on the labor income share of enterprises.The results show that digital global value chain embedding can significantly promote the increase of labor income share of enterprises,and can indirectly affect it by reducing the external transaction costs of enterprises.The digital global value chain is embedded in different digital economic development thresholds,and the promotion effect on the labor income share of enterprises shows a non-linear feature of marginal increase.Digital global value chain embedding has a stronger role in promoting the labor income share of mature enterprises and manufacturing enterprises.Based on this,suggestions are put forward to improve the embedment level of digital global value chain,accelerate the digital transformation of enterprises,and promote the high-quality development of digital economy,so as to provide beneficial theoretical support for increasing the labor income share of enterprises.
