中国东部沿海三大城市群科技创新与绿色发展耦合协调关系研究

Research on Coupling Coordination Relationship between Technology Innovation and Green Development in Three Chinese Coastal Urban Agglomerations

摘要:

基于2009-2017年中国东部沿海三大城市群34个城市面板数据，运用耦合协调度模型和障碍度模型, 厘清科技创新与绿色发展的耦合协调关系及其障碍因素的空间异质性特征。结果表明：三大城市群科技创新和绿色发展指数保持平稳增长状态，指数均值由大到小依次为珠三角、长三角和京津冀城市群，城市群内各城市发展存在显著不均衡；三大城市群科技创新与绿色发展耦合协调关系不断改善，珠三角和长三角城市群处于磨合阶段，京津冀城市群尚处于拮抗耦合阶段，三大城市群整体表现为失调型，协调关系仍需进一步改善；三大城市群各参数对科技创新与绿色发展协调发展的影响呈趋同性，创新投入、产出、储备及绿色生活建设是制约三大城市群科技创新与绿色发展的主要障碍因素。

Abstract:

Based on the panel data of 34 cities in three Chinese coastal urban agglomerations from 2009 to 2017, the coupling coordination relationship between technological innovation and green development is estimated by using the Coupling Coordination Model and the obstacle degree of each factor is calculated by using the Obstacle Degree Model. The results show that: Firstly, both of the technological innovation and green development index of the three urban agglomerations keep growing steadily. From large to small, the order of the average value of the two indexes is Pearl River Delta, Yangtze River Delta and Beijing Tianjin Hebei Urban Agglomerations. There is significant imbalance in the development of both technical innovation and green development in cities within each urban agglomeration. Secondly, the coupling and coordination relationship between technology innovation and green development of the three urban agglomerations have been improved continuously. The Pearl River Delta and Yangtze River Delta urban agglomerations are in the running-in stage, while the Beijing Tianjin Hebei urban agglomerations is still in the antagonistic coupling stage. Generally, the coupled development between technology innovation and green development in the three urban agglomerations is imbalanced, indicating that the coordination relationship needs to be further improved. Thirdly, the parameters have the influence of each parameter on the coordinated development between technology innovation and green development differs slightly among the three urban agglomerations. The main obstacle factors that restrict the coupled development between the technology innovation and green development are innovation input, output, reserve and green life construction.
