## 5 Conclusions and Policy Implications
### Countermeasures and Policy Implications  
#### 5.2.1 Promote Regional Coordinated Development and Build a Long-Term Interactive Mechanism  
The level of technological and scientific advancement and environmentally friendly development in coastal areas is experiencing significant growth. To expedite the execution of the strategy to enhance the country's strength through quality, we must seize development opportunities and uphold the comprehensive trend of advances in science and technology and ecological environment optimization. Additionally, we should actively establish a long-term interactive mechanism to coordinate the development of both aspects. This will promote the regularity of coordinated development and sustain the economic vitality of coastal regions. In order to enhance economic vitality, it is imperative to foster and enhance the growth of environmentally friendly initiatives within the market system. This entails establishing a positive feedback loop of market competition, developing a platform for showcasing innovative green products, and creating a conducive ecological environment. Additionally, it is crucial to facilitate comprehensive, efficient, and expeditious information exchange within the region. While the development of provinces and regions in coastal areas is currently in a stage of well-coordinated development, there is still potential for future progress in terms of the overall development level and trend. According to the notion of competitive advantage, regions and cities with less developed goals achieve a favorable position of \"coordinated development from the strong to the weak\" [34]. We must fully release the development dividends and radiation effects of advantageous coastal regions, promote the overall coordinated development of the country with regional advantages, further enhance competitiveness in the international market, and attract international investment and tourism. By promoting regional coordination, ecological transformation of industrial structures, and ecological development environments, other countries can also learn from this model, integrate sustainable development into their national development strategies, and promote global green development and ecological civilization. At the same time, to promote coordinated development among regions, this policy proposal shows other countries the critical role of regional coordination in promoting economic development and enhancing regional competitiveness. By learning this cooperation mode, we can strengthen cooperation and exchanges between regions and jointly cope with future global challenges. 2.2 Achieve Green Development of Science and Technology and Ecological Transformation of Industrial Structure  
We will enhance our investment in scientific and technology innovation, prioritize environmental protection, and actively facilitate the ecological transformation of our industrial structure. The coastal areas should develop a coordinated and rational system for assessing technological innovation and ecological environment, taking into account the specific characteristics of regional development. This system should prioritize the technological advancement of traditional enterprises and the optimization of the urban ecological environment. Additionally, differentiated strategies should be implemented. The emphasis of innovative scientific and technological development should be appropriately shifted towards the specific attributes of coastal scientific and technological enterprises. This should be conducted by prioritizing science and technology as the foundation and innovation as the primary focus of research, in order to achieve progress in scientific and technological innovation development. Simultaneously, it is crucial to prioritize the preservation of the natural environment and promote ecological innovation in relevant businesses, fostering a path towards environmentally friendly and sustainable development.
