【摘要】 在制度型开放背景下探讨自由贸易试验区建设赋能新质生产力发展的政策效果，具有重要意义。文章将自由贸易试验区建设视为准自然实验，基于2010—2022年中国沪深A股上市公司样本数据，运用多期双重差分法检验自由贸易试验区建设赋能新质生产力发展的政策效果。研究发现，自由贸易试验区建设能够有效赋能新质生产力发展，并且较低的媒体关注和较好的法律环境可以使这一政策效果更显著。机制检验表明，自由贸易试验区建设可以通过缓解融资约束和激活市场竞争有效赋能新质生产力发展。拓展分析发现，新质生产力存在显著的行业同群效应，而自由贸易试验区建设能够有效赋能新质生产力的行业同群效应。研究结论可以为企业如何培育和发展新质生产力提供来自制度型开放视角的理论依据和经验支撑。更多还原

【Abstract】 It was important to explore the policy effect of the construction of pilot free trade zones(FTZ) to enable the development of new quality productive forces(NQPF) under the background of institutional opening-up. In this paper, we considered FTZ as a quasi-natural experiment, Based on the sample data of A-share listed companies in China from 2010 to 2022, and used the time-varying DID method to assess the policy effect of FTZ to empower the development of NQPF. It was found that FTZ could effectively enable the development of NQPF and lower media attention and a better legal environment could make the policy effect more significant. The mechanism analysis showed that the construction of FTZ could promote the development of NQPF mainly by alleviating their financing constraints and activating market competition. Extended analysis revealed that NQPF exhibited significant industry peer effects, and the construction of FTZ could effectively enhance the industry peer effects of NQPF. The research conclusion could provide a theoretical basis and empirical support for how enterprises cultivate and develop NQPF from the perspective of institutional opening-up.更多还原
