摘　　要：本文利用2007—2018年中国A股上市公司数据,以2011年《社会保险法》实施为准自然实验构建双重差分模型,考察了劳动保护对企业金融资产投资的影响。研究发现,《社会保险法》的实施显著提高了企业金融资产投资水平。机制检验表明,《社会保险法》的实施加剧了企业的融资约束,企业出于预防动机通过增持短期金融资产以补足流动性。异质性分析发现,对于国有企业和所处地区税收征管力度强的企业,《社会保险法》实施对其持有金融资产的诱导作用更为显著。经济后果分析发现,企业出于预防性储蓄目的从事的金融资产投资,并未兼顾金融资产投资效率。本文认为在实施劳动保护措施的同时,应当注意警惕企业过度配置金融资产,提高决策能力。In recent years,the real economy,especially the manufacturing sector,faces a dual impact of macroeconomic downturn and overcapacity,which leads to a gradual decline in its traditional competitive advantage while the financial industry rapidly expands.Many firms turn to invest in financial assets to seek new profit opportunities,gradually diverting resources from the healthy growth of core operations.Such risk accumulation hampers the progress of China's high-quality economic development.Therefore,it is crucial to explore the driving factors behind corporate financial asset investment and understand its true motivation from a more diverse perspective.Using the data of A-share listed companies in China from 2007 to 2018,this paper constructs a DID model based on the enactment of Social Insurance Law(SIL)in 2011 as a quasi-natural experiment,and examines the impact of labor protection on corporate financial asset investment.The study finds that the implementation of SIL significantly improves the level of corporate financial asset investment.Mechanism testing shows that the implementation of SIL intensifies the financing constraints of firms,and firms,motivated by prevention,increase their holdings of short-term financial assets to supplement liquidity.Heterogeneity analysis finds that for state-owned firms and firms with strong tax collection and management in their respective regions,the implementation of SIL has a more significant inducing effect on their holding of financial assets.Specifically,economic consequence analysis finds that financial asset investment conducted by firms for precautionary savings does not take into account the efficiency of financial asset investment.This paper has the following contributions:(1)It expands the cross research between labor protection and corporate finance,supplementing the research gap on the economic consequences of corporate financial asset investment.(2)It enriches the research on the influencing factors of corporate financial asset investment,expanding the relevant r
