As one of the most active regions in China’s economic development, various strategic emerging industries in the Yangtze River Delta has been continuously emerging in recent years. Since most of the strategic emerging industries are closely related to scientific and technological innovation, it is crucial to promote scientific and innovative finance to support the development of strategic emerging industries in the Yangtze River Delta. Firstly, the relevant policy background was sorted out, and the goal of the integrated development of strategic emerging industries in the Yangtze River Delta was drawn out. Then, the development status of scientific and innovative finance and strategic emerging industries in the Yangtze River Delta was sorted out, which highlighted the important role of scientific and innovative finance in the development process of strategic emerging industries in the Yangtze River Delta. Then, the problems of scientific and innovative finance in the development of strategic emerging industries in the Yangtze River Delta were summarized, including regional development imbalance, single financing channels, institutional guarantee to be improved, and scientific and technological innovation ecological construction to be strengthened. Finally, policy suggestions are proposed, including establishing a multi-level financial system for scientific and innovative finance, promoting the virtuous cycle of “science and technology-industry-finance”, accelerating the innovation and development of green science and technology, and improving the level of data intelligence of scientific and innovative finance.

During the 14th Five-Year Plan period, Gansu Province has planned to construct the Lanzhou Metropolitan Area with Lanzhou City as the core and its adjacent municipal areas as the hinterland. With the rapid construction and layout of regional transportation facilities, the external transportation pattern of the Lanzhou Metropolitan Area has gradually taken shape. Based on the big data of population migration within the metropolitan area, the current situation of transportation between cities was studied, and the integrated layout of transportation facilities was optimized. The results of the characteristics of the inter-city travel network of residents constructed based on different time periods and different transportation modes indicate that the overall travel network of regional residents presents a “radiation-shaped” pattern centered on Lanzhou. The travel scale and stability of the routes between Lanzhou and the cities in the hinterland are large, while the connections between the hinterland cities are relatively weak. Compared with the daily period, the travel intensity during special holidays and the “Spring Festival travel rush” increases, but it is still dominated by large-scale daily routes. Road transportation is the main mode of regional travel. Conventional railways no longer meet the needs of rapid inter-city travel, while high-speed railways promote large-scale inter-city travel. Based on the current characteristics, optimization strategies for the transportation integration of the Lanzhou Metropolitan Area are proposed respectively from the three transportation modes of aviation, railways, and roads to promote regional coordinated development.

Cities are important carriers of regional development, which can play a leading role in regional coordinated development, and the study of urban development level can better grasp the essence and direction of regional development. Based on the traditional gravitational model, a gravitational model was constructed to measure the gravitational strength between cities and the relative gravitational strength of a single city in Gansu Province in 2012 and 2022 with the help of relevant data of population, economy, society, ecology and transportation in 14 cities in Gansu Province, and the evolution of urban spatial gravitational network structure was analyzed. Based on the regional strategy of “one core and three belts” in Gansu Province, the study concludes that the core position of gravitational strength in Lanzhou is significant, and it has a driving effect on the surrounding cities. The Jiuquan-Jiayuguan area has become the sub-center of gravitational intensity, which has not had an obvious driving effect on the surrounding cities. There are significant differences in gravitational values among cities in different regions of the province. The gravitational network structure of urban space has gradually evolved from irregular to “pendulum-shaped” structure. The development of each city should formulate development strategies according to the actual situation of inter-city gravity and urban quality, so as to solve the current situation of backward development of the economic belt of the Hexi Corridor and the ecological function belt of the upper reaches of the Yellow River.

There are 3 866 ancient and famous trees in Taiyuan, belonging to 30 families, 52 genera and 62 species, mainly Zizyphus jujuba, Sophora japonica, Platycladus orientalis, Pinus tabulaeformis and other native species. Through the analysis of nuclear density, it is found that 9 regions with higher estimated nuclear density are formed in the central and eastern regions of Taiyuan. The main gathering areas of jujube, Chinese sophora, platycypress and Pinus tabulatus, which have the largest number of ancient and famous trees, are located in the central, eastern and southern, southern, central and northeastern regions of Taiyuan respectively. Based on historical documents, the historical and cultural values of these four major tree species are expounded from the perspectives of folk customs, religious beliefs and ancient city history.

The Upper Yellow River City Cluster is the highest form of urban spatial organization in Northwest China, and it is the region with the closest exchange of materials, information and people among the cities in the upper Yellow River. In this paper, the gravity model was optimized and improved in terms of two dimensions, such as the assessment of the comprehensive strength of cities as well as the absolute and relative linkage strength, and the improved gravity model was used to evaluate the characteristics of urban spatial linkages of 10 cities in the Upper Yellow River City Cluster from 2018 to 2021, and to analyze their spatial patterns and evolution. The results show that large cities in the Upper Yellow River City Cluster show more radiation effects, while small cities are more attracted by external cities. With the passage of time, the strength of the connection between cities has been strengthened, gradually forming a spatial pattern of transition from “single nucleus” to “multiple nuclei”, with the spatial layout showing one center, three circles, three nuclei in the shape of V, and the Yellow River becoming an axis and cities being in the same belt, and the spatial pattern of the cities can be classified as follows Three groups, such as Lanzhou City Group, Yinchuan City Group, Xining City Group. There is a big difference in the development of each cluster, and it is urgent to find the development path to realize the differentiated development.

In order to search for a new model suitable for the development of collaborative innovation in the biomedical industry in LZ city, the current situation and problems of biomedical industry in LZ city were sorted out through literature analysis and investigation, comparing the existing collaborative innovation development modes in LZ city, and combining with the theory of collaborative innovation to search for new modes suitable for its development of collaborative innovation. It is found that LZ city biomedical industry has a variety of collaborative innovation models, on the basis of which it is necessary to form a closer government-industry-academia-research-utilization of the new mode of collaborative innovation. At present, the most suitable model for biomedical development in LZ city is the new model of collaborative innovation between government-industry-academia-research-application based on joint decision-making by multiple subjects, multi-stage synergy and scientific distribution of benefits and close relationship.

Improving the ecological resilience of the Yellow River Basin is an important aspect of ecological protection and high-quality development.A spatial econometric model was used to analyze the impact of digital economy on ecological resilience in 66 cities in the Yellow River Basin from 2011 to 2020.The results indicate that the overall level of ecological resilience in the Yellow River Basin is relatively low, with slow development and further widening regional disparities. The role of digital economy in ecological resilience has obvious nonlinear characteristics, with a more significant impact on the entire watershed and upstream, while the impact on the midstream is less significant. The impact of the digital economy on ecological resilience has a significant spatial spillover effect, with direct and indirect benefits across the entire watershed. The direct effect is dominant in the middle and lower reaches, while the spatial spillover effect in the upstream is not significant. The main reasons for the non-linear effect of digital economy on ecological resilience are the differences in economic development, government intervention, and foreign investment.

Optimizing the business environment is an important prerequisite for promoting high-quality economic development. Based on the data of Zhejiang Province and its 11 prefecture-level cities from 2013 to 2022, the coupling coordination degree model was used to explore the coupling and coordination relationship between business environment and economic growth in Zhejiang Province as a whole and in each prefecture-level city. The results show that the overall level of coupling and coordination between business environment and economic growth in Zhejiang Province is increasing year by year. Among them, the coordinated development of Hangzhou and Ningbo is particularly prominent. The coordinated development level of Wenzhou, Shaoxing, Jiaxing, Taizhou, Jinhua, Huzhou and Zhoushan has been improved, but it is still insufficient. Quzhou and Lishui are still in a state of imbalance, and it is urgent to further optimize the business environment to promote coordinated economic development.

Given the uniqueness of world heritage resources, an increasing number have been developed into tourism resources to attract tourists from various regions. Based on theories related to tourism spatial structure, such as the tourism location theory, the central place theory, and the growth pole theory, a study on the tourism spatial structure of the world cultural heritage sites in Quanzhou was conducted. Through kernel density analysis, it is concluded that the world cultural heritage sites in Licheng District and Fengze District of Quanzhou present a dense distribution in a planar form, while those in Jinjiang City and Shishi City show a dense point distribution, and in other counties and cities, they are dispersed in a point pattern. Issues exist such as an imbalanced overall spatial distribution of the heritage sites, insufficient exploitation of tourism resource advantages, inadequate exploration of heritage value and integration of resources, and a relatively low influence of the tourism brand. For this reason, a tourism spatial pattern of “one belt-three zones-six cores” is constructed in the approach of tourism spatial structure. According to this pattern, strategies such as optimizing the spatial layout, perfecting the design of tourism routes, deepening the integration of culture and tourism, strengthening the combination of virtual and real elements, and enhancing regional cooperation are proposed to enhance the cultural value and tourism brand effect of the world cultural heritage sites in Quanzhou and promote the flourishing development of tourism.
