科技服务业集聚如何影响企业出口持续时间?

How Does S&T Services Agglomeration Affect Export Duration of Enterprises?

制造企业出口持续时间是中国出口供应链安全的重要内容,科技服务业集聚是构建现代化产业体系的重要考量。文章基于2000-2014年中国工业企业与海关进出口匹配数据,运用生存分析模型,就科技服务业集聚与企业出口持续时间之间的关系与作用机制进行实证分析。研究发现,科技服务业集聚显著降低了企业出口退出风险,延长了企业出口持续时间。在一系列稳健性检验后,基准回归结果仍然成立,且科技服务业集聚更加有助于提高年轻企业和中年企业、民营企业、东部地区、技术密集型以及加工贸易企业的出口生存率,延长其出口持续时间。机制分析表明,科技服务业集聚通过提高企业全要素生产率和提升企业出口技术复杂度增强了出口企业的风险抵御能力,延长了企业出口持续时间。

The duration of export activities in manufacturing enterprises is a crucial element of export supply chain security in China,and S&T services agglomeration is a key consideration in building a modern industrial system.Using survival analysis models and data from Chinese industrial enterprises and customs import-export matches between 2000 and 2014,this study empirically analyzes the relationship and mechanism between S&T services agglomeration and the duration of enterprise exports.The research finds that S&T services agglomeration significantly reduces the risk of export exit and extends the duration of export activities.After a series of robustness checks,the baseline regression results remain valid,and S&T services agglomeration is found to more effectively improve the export survival rates of younger and mid-aged enterprises,private enterprises,those in eastern regions,technology-intensive enterprises,and processing trade enterprises,thereby extending their export duration.Mechanism analysis shows that S&T services agglomeration enhances the risk resilience of export enterprises by improving the total factor productivity and increasing the export technological complexity,thereby prolonging the export duration of enterprises.
