This study employs a CES production function to construct a theoretical model of labor income share and uses a two-way fixed effects model to test the causal effects of local government debt (LGD) on the labor income share of enterprises. Local government debt governance policies are utilized as exogenous shocks, and a DID (Difference-in-Differences) model is applied for endogeneity testing. The results have passed a series of robustness checks. The findings suggest that LGD decreases the share of firms' labor income. The mechanism analysis suggests that LGD lowers the labor remuneration of residents, the employment of labor in enterprises, and the size of bank loans mainly; while raising the cost of using funds in enterprises. Moreover, this negative effect is more apparent in non-state-owned enterprises, small and medium-sized enterprises, and enterprises with high financing constraints. This study presents new evidence on how the labor income share of enterprises is affected from the perspective by local governments in China. It has important implications for further deepening local government debt governance and achieving common prosperity.
本研究运用 CES 生产函数构建了一个理论模型,用以考察地方政府债务(LGD)对企业劳动收入份额的因果效应。利用地方政府债务治理政策作为外生冲击,采用双重差分模型(DID)进行内生性检验。研究结果通过了一系列稳健性检验。研究结果表明,地方政府债务降低了企业劳动收入份额。机制分析表明,地方政府债务主要通过降低居民劳动报酬、企业劳动就业、银行贷款资金使用成本,提高企业资金使用成本,进而降低企业劳动收入份额。此外,这种负向效应在非国有企业、中小企业和融资约束较高的企业中更为明显。本研究从地方政府视角为企业劳动收入份额的决定提供了新的证据,对进一步深化地方政府债务治理、实现共同富裕具有重要意义。
