链长制是否提升了产业链韧性?OA

Enhancing the resilience of industrial chains is a critical indicator of their optimization and upgrading.In response to the demands of the era for high-quality economic development and the practical challenges of improving industrial chain foundations and governance capabilities,the Chinese-style chain chief system has e-merged.This paper treats the implementation of the chain chief system policy as a quasi-natural experiment.Based on panel data from 30 provinces in China covering the period 2011-2020,a multi-period difference-in-differences model is constructed to investigate the policy effects of the chain chief system's implementation on en-hancing industrial chain resilience.The research findings indicate that the chain chief system can significantly enhance industrial chain resilience,a conclusion that remains robust after a series of validity checks.The effect of the chain chief system on improving industrial chain resilience exhibits heterogeneity.Furthermore,the level of marketization plays a significant positive moderating role in the relationship between the chain chief system and industrial chain resilience enhancement.Grounded in the principle of better integrating an effective market with a proactive government,the following countermeasures and suggestions are proposed:clarify functional positioning and responsibility boundaries;promote the chain chief system in a differentiated manner based on regional characteristics and advantages;and fully leverage the moderating effect of the marketization level.This research pro-vides Chinese insights and solutions for the steady and prudent advancement of the chain chief system,the strengthening of industrial chain modernization,and the en-hancement of modern economic governance capabilities.
