城市网络与创新能力间的时空关系研究 --以成渝城市群为例

Spatial and temporal relationship between urban network and innovation capability

摘要:

摘要：以创新为动力，以城市群为载体是我国未来一段时期重要的经济发展战略。并且创新能力的持续提升也愈发受到城市网络的影响。据此，本文以正在发育的成渝城市群为研究对象，以城市间百度指数和联合专利为变量构建城市网络，并从创新产出、投入、环境三方面对创新能力进行测度，随后利用象限图法对二者间的相关性及其时空变化做出分析。最后，运用障碍度模型对成渝城市群创新能力进一步提升的相关阻碍因素进行识别，从而为日后该地区城市网络发展规划更好地服务于创新能力的提升提供政策建议。

Abstract: Taking innovation as the driving force and urban agglomeration as the carrier is an significant economic development strategy for a period of time in the future. Moreover，the continuous improvement of innovation capacity is increasingly affected by the urban network. Therefore, this paper takes the developing Chengdu-Chongqing urban agglomeration as the research object, constructs the urban network with the inter-city Baidu index and joint patent as the variables, measures the innovation capacity from the three aspects among innovation output, input and environment, and then uses the quadrant diagram to analyze the correlation between the two and their spatial-temporal changes. Finally, the obstacle degree model is used to identify the relevant obstacles to the further improvement of the innovation ability of Chengdu-Chongqing urban agglomeration, so as to provide policy suggestions for the future urban network development planning in this region to better serve the improvement of the innovation ability.
