邻近性视角下长三角协同创新绩效影响因素实证研究

An Empirical Study on the Influencing Factors of Collaborative Innovation Performance in the Yangtze River Delta from the Perspective of Proximity

摘要:

长三角地区被称作“中国经济增长的发动机”。跨区域协同创新是区域创新全面升级的必然选择。然而，区域壁垒等因素严重阻碍了区域间的协同创新。本文以江浙沪三地为研究对象，结合三地2008—2016年的面板数据，探讨了制度临近性、认知邻近性和经济邻近性等因素对协同创新绩效的影响。实证结果表明：经济邻近性和制度邻近性能够促进协同创新绩效的提升；认知邻近性与协同创新绩效的关系呈倒U形。模型测度结果显示，江浙沪地区之间的认知邻近性较高，已对协同创新绩效产生了抑制作用。经济邻近性和制度邻近性对跨区域协同创新绩效尚处于正向影响阶段。破除行政壁垒；加强分工协作，优化产业结构；密切经济合作，缩小经济发展差距是推进长三角经济社会一体化的基础。

Abstract:

The Yangtze River Delta region is known as the "engine of China's economic growth." Cross-regional collaborative innovation is an inevitable choice for the comprehensive upgrading of regional innovation. However, factors such as regional barriers have seriously hampered collaborative innovation among regions. This paper takes Jiangsu, Zhejiang and Shanghai as research objects, and combines the panel data of 2008-2016 in three places to explore the influence of institutional proximity, cognitive proximity and economic proximity on collaborative innovation performance. The empirical results show that economic proximity and institutional proximity can promote the improvement of collaborative innovation performance; the relationship between cognitive proximity and collaborative innovation performance is inverted U-shaped. The model measurement results show that the cognitive proximity among Jiangsu, Zhejiang and Shanghai regions is high, which has inhibited the synergistic innovation performance. Economic proximity and institutional proximity are still in a positive impact on cross-regional collaborative innovation performance. Break down administrative barriers, strengthen division of labor and cooperation, optimize industrial structure, close economic cooperation and narrow the gap in economic development are the bases for promoting economic and social integration in the Yangtze River Delta.
