## 4 Results and Analysis
### Comprehensive Level Measurement of Each System
In addition, other provinces have also experienced varying degrees of growth, such as Hebei, Shanghai, Zhejiang, Fujian, Shandong, and other provinces, which have improved from moderate coupling coordination to good coupling coordination, further indicating that the coupling and coordinated development of the two systems in coastal areas is continuing to be optimized. There are increasing levels of coupled coordinated changes due to the following reasons:  
1 Innovation in science and technology has led to technological advancement, resulting in a more environmentally friendly economic development mode and an improved ecological environment. As scientific and technological innovation advances, new technologies, materials, and processes are continually being developed. These discoveries drive economic growth and facilitate the transition to new forms of economic development. The green development mode is gradually supplanting the old production mode, characterized by high pollution and high energy consumption, with a mode focusing on low pollution,

low energy consumption, and high efficiency. This transition has successfully safeguarded the natural environment in coastal regions, diminished pollution discharges, and enhanced environmental quality. In Jiangsu and Guangdong provinces, adopting new energy technologies has led to a steady rise in the use of clean energy sources like wind and solar energy. This has resulted in the replacement of certain traditional fossil fuels in the energy structure. This mitigates the release of greenhouse gases and fosters the enhancement of the local biological environment. Simultaneously, both provinces aggressively advocate for adopting clean production technology to mitigate industrial pollution, achieving a mutually beneficial outcome of economic growth and environmental protection. 2 The ongoing advancement of technological and scientific developments has led to the enhancement of technology, the acquisition of talent, and the emergence of a green economy to foster the development of an environmentally conscious society. The ongoing advancement of technological and scientific advances facilitates the enhancement of technology and offers substantial human resources to assist the creation of an ecological civilization. An increasing number of scientific and technological experts are dedicating their efforts to researching environmental protection, ecology, and related topics. This influx of intellectual talent is a reliable source of support for developing an ecological society. Simultaneously, advances in technology and science have given rise to a green economy and facilitated the improvement and modernization of economic systems. Zhejiang has been at the forefront in recent years. Through advancing scientific and technological breakthroughs, we will actively pursue establishing environmentally friendly economic models, explicitly focusing on circular and low-carbon economies. The achievement of efficient resource utilization, trash reduction, and recycling is made possible by technical innovation. Furthermore, Zhejiang has proactively recruited and nurtured highly skilled individuals in environmental protection. It has developed multiple environmental research institutions and innovative technological platforms, which have played an essential part in supporting the development of an ecological society. 3 The national plan is being implemented to construct a society prioritizing ecological civilization. This strategy aims to expedite the shift towards scientific and technological breakthroughs and enhance the capabilities in this field. The coastal areas actively respond to the national plan by embracing the call to establish a society focused on ecological civilization. They are also expediting the shift towards adopting ecological scientific and technical innovation concepts.
