摘要/Abstract

摘要： 合作创新是企业提升创新能力、分担创新风险的重要途径，也是驱动中国经济转型升级、实现高质量发展的内生动力。本文使用2000—2013年中国工业企业数据，利用中国高速公路交通网络构建市场可达性指标，通过Heckman两步法、工具变量法与调节效应模型等方法考察其对企业异地合作创新的影响及其作用机制。研究发现，市场可达性的提升，从广延边际、集约边际以及跨区域合作强度三方面显著促进了企业异地合作创新，稳健性检验与内生性检验均支持上述结论。机制检验结果表明，市场可达性的提升通过降低交易成本和提升知识匹配度两条途径促进企业异地合作创新。异质性分析发现，市场可达性提升对位于外围城市的企业、国有企业以及所处市场竞争环境更为激烈的企业进行异地合作创新的促进作用更为明显。本研究为“交通强国”建设的必要性和迫切性提供了新的理论支持和经验证据。

Abstract: Collaborative innovation is an important approach for firms to enhance their innovative capabilities and share innovation risks. It is also a crucial intrinsic driving force for China′s economic transformation, upgrading and achieving high-quality development. This study utilized the panel data of Chinese industrial enterprises from 2000 to 2013, and constructed the market accessibility index constructed from China′s highway transportation network to examine its influence on firms′ inter-regional collaborative innovation and its underlying mechanisms through Heckman′s two-step test, instrumental variable test and moderating effect test. The research findings revealed that the improvement of market accessibility significantly promotes firms′ inter-regional collaborative innovation from the perspectives of extensive margins, intensive margins, and inter-regional cooperation intensity. The robustness tests and endogeneity tests supported the conclusions. The mechanism tests demonstrated that the enhancement of market accessibility promotes firms′ inter-regional collaborative innovation by reducing transaction costs and enhancing knowledge matching. The heterogeneity analysis further indicated that the enhancement of market accessibility more significantly facilitates inter-regional collaborative innovation for firms located in peripheral cities, state-owned enterprises, and those operating in more competitive market environments. This study will provide new insights and empirical evidence for the necessity and urgency of building a "transportation powerhouse".
