技术创新合作网络与经济网络演化特征及协同关系研究

加快技术创新合作,促进城市经济互动,有利于缩减区域差距,最终实现协调发展.本研究基于社会网络分析和引力模型的方法,分析中国30个省会城市技术创新合作网络与经济网络的时空演进特征,研究发现:省会城市间的直接技术创新合作不断增强且呈现多中心化趋势,合作突破地理局限且东西部差异较为明显;城市经济网络密度有所增强但整体偏低,核心区域与边缘区域的经济联系发展不均衡,各城市在经济网络中位置变化不明显.二次指派问题(Quadratic Assignment Problem,QAP)分析表明技术创新合作网络与经济网络存在正相关关系,格兰杰检验进一步证明二者互为因果关系,但技术创新合作网络对经济网络的影响更为显著.

Research on the evolution characteristics and collaborative relationship between technological innovation cooperation network and economic network

Accelerating technological innovation cooperation and promoting urban economic interaction are conducive to reduce regional gap and ultimately achieve coordinated development. Based on the method of social network analysis and gravitation model, this paper analyzes the temporal and spatial evolution characteristics of technological innovation cooperation network and economic network of 30 central cities in China. It is found that the direct technological innovation cooperation between provincial capitals is increasing and showing the trend of multi centralizations. Technological innovation cooperation breaks through the geographical limitations and its difference between the East and the West is obvious; The density of urban economic network is increasing but the whole is still low. The development of the economic connection between the core area and the edge area is not balanced, and the position of each city in the economic network does not change significantly. QAP analysis shows that there is a positive correlation between technological innovation cooperation network and economic network. Granger causality test further proves that the two are cause and effect mutually, but the technological innovation cooperation network has more significant influence on economic network.
