珠三角地区科技创新与生态环境的耦合协调发展研究

探究科技创新与生态环境之间的耦合协调关系,是当前我国高质量发展过程中亟待解决的关键问题。通过探讨科技创新与生态环境的耦合协调机制,构建两者的综合评价指标体系,借助物理学耦合协调度模型定量测算2007-2018年珠三角地区科技创新与生态环境的耦合协调度,并对其时空演化特征进行探讨分析。结果表明:珠三角各市的科技创新综合指数与生态环境综合指数均呈现不断上升的趋势,且两者耦合度、耦合协调度也呈现出由低水平向高水平的演进特征。在空间分布上,珠三角地区科技创新与生态环境的耦合协调度呈现出以珠江入海口城市"广深佛莞"为中心,向两侧递减的空间格局。在作用类型上,珠三角多数城市在2007年的科技创新能力起到明显地滞后作用,但随着时间的推移,城市创新能力不断增强,与生态环境之间达到基本协调,甚至高级协调水平;而肇庆市发展相对缓慢,仍处于"基本失调-科技创新受阻型"。以区域高质量发展为引领,通过加大创新要素投入、控制污染物排放、合理布局生态用地等方法提高生态创新,有助于未来珠三角实现科技创新与生态环境协调可持续发展。

Coupling and coordinated development between technological innovation and ecological environment in the Pearl River Delta region

It is vital for China to investigate the coupling and coordination relationship between technological innovation and ecological environment to accomplish its high-quality development strategy currently. In order to solve the question mentioned above, this paper firstly elaborated the mechanism process of the coupling and coordination relationship between technological innovation and the ecological environment. After that, the paper chose the Pearl River Delta region as the study area. A comprehensive evaluation indicator system was constructed to evaluate the situation of technological innovation and ecological environment in the Pearl River Delta region from 2007 to 2018. Subsequently, we quantitatively calculated the coupling coordination level between technological innovation and ecological environment with the help of coupling coordination degree model of physics. What''s more, the paper analyzed and discussed the spatiotemporal evolution characteristics of their coupling coordination development situation in the Pearl River Delta region. Our findings are as follows. Firstly, both the situation of technological innovation and ecological environment showed a gradual upgrade trend in all cities of the Pearl River Delta from 2007 to 2018. More importantly, the coupling degree and the coupling coordination degree between technological innovation and ecological environment also presented the positive characteristics that moved from low level state to more advanced state. As for spatial distribution, the coupling coordination degree between technological innovation and ecological environment in the Pearl River Delta region showed a significantly spatial pattern which descended from the core region to the periphery, meanwhile, Guangzhou, Shenzhen, Foshan and Dongguan such developed cities are situated in the central area. In terms of coupling and coordinated types, although most cities'' technological innovative ability hindered the improvement of coupling coordination degree between technological innovation and the ecological environment after 2007, the innovation ability of cities has been continuously captured with the ecological environment which pushed the coupling coordination degree to reach the basic coordination or even advanced level as time goes on. However, the development of Zhaoqing was slow compared with other cities, and it still belonged to the basic imbalance-technological innovation hindered type during the study period. Therefore, under the guidance of regional high-quality development strategy, we concluded several developmental strategies for the Pearl River Delta to implement the coordinated and sustainable development of technological innovation and ecological environment, for example, improving ecological innovation by increasing investment in innovation factors, controlling pollutant emissions and reasonably maintaining ecological land.
