政府数字化采购能否促进企业数字化转型OACHSSCD

This study investigates whether digital procurement by government agencies can fa-cilitate the digital transformation of firms,using a unique dataset that combines transaction-level data from the China Government Procurement Network and financial and textual data from A-share listed firms between 2014 and 2020.We construct a novel proxy for government digitali-zation based on the intensity of digital procurement activities at the city level and empirically ex-amine its spillover effects on firm-level digital transformation.Our baseline results reveal that government digital procurement significantly promotes firm digitalization,and this effect remains robust after a series of sensitivity tests,including alternative variable specifications and instru-mental variable estimation.Mechanism analyses indicate that digital procurement reduces firms'perceived policy uncertainty,fosters the local concentration of digital talent,and increases man-agerial attention to digital transformation,thereby accelerating firms' adoption of digital technol-ogies.Furthermore,heterogeneity analyses show that the effect is more pronounced for non-state-owned enterprises,firms with technically trained executives,and firms located in cities with higher fiscal autonomy or stronger digital infrastructure.Our findings offer new insights into the external institutional drivers of firm digitalization and provide evidence-based implications for pro-moting digital transformation through public sector innovation.
