自由贸易协定(FTA)为企业参与全球分工提供便利、稳定和可预期的制度环境。嵌入FTA网络是企业深化全球价值链分工、应对全球化不确定性的重要途径。基于中国A股上市公司数据，构建企业层面的FTA网络嵌入指标并测算企业全球价值链参与长度，揭示企业嵌入FTA网络对其全球价值链参与长度的影响与作用机制。研究发现，企业FTA网络嵌入程度的提高，显著促进其全球价值链参与长度延伸。机制检验表明，FTA网络嵌入通过降低制度性交易成本、增强进出口多元化和提升全球价值链嵌入程度，推动企业全球价值链参与纵向延伸。市场竞争越激烈、中间品投入份额越高的企业，嵌入FTA网络促进延链的效应越强。
Abstract：Free Trade Agreements(FTAs) provide a convenient, stable and predictable institutional environment for enterprises to participate in the global division of labor. Embedding in the FTA network is an important approach for enterprises to deepen their division of labor in the global value chain(GVC) and navigate the uncertainties of globalization. Based on data of China's A-share listed companies, this study constructs a firm-level FTA network embedding index and measures firms' GVC participation length, so as to reveal the impact and mechanism of firms' FTA network embedding on their GVC participation length. The study finds that the improvement of firms' FTA network embedding significantly promotes the extension of their GVC participation length. Mechanism tests show that FTA network embedding drives the vertical extension of firms' GVC participation by reducing institutional transaction costs, enhancing import and export diversification, and improving the degree of GVC embedding. The more intense the market competition and the higher the share of intermediate inputs, the stronger the value chain lengthening effect of FTA network embedding.
