Tanhuasi Park was selected as the case area to collect photos and sounds, and the proportion of each element was identified by image semantic segmentation. Then, according to the saliency and universality of the sound, the sound of birdsong, the sound of water flowing, the sound of wind, and the sound of communication were selected, and the sound and picture were edited by Adobe Premierepro, and the questionnaire was filled in to calculate the recovery value of different sounds. The correlation analysis between landscape elements and sound was carried out, and it was concluded that birdsong had a significant positive correlation with tree and shrub coverage and plant species, water flow sound had a significant positive correlation with water quality and waterscape coverage, and communication sound was negatively correlated with the richness of landscape sketches. Based on this, strategies for improving the green space environment of urban parks are proposed.

The integrated development of urban and rural areas,as an important component of the path of socialist rural revitalization with Chinese characteristics,has received widespread attention from researchers in recent years.Based on CiteSpace software, CSSCI(Chinese Social Science Citation Index) related literature in the field of urban-rural integration development from January 2015 to September 2024 was taken as the research object,which is included in the academic journal database of CNKI(China National Knowledge Infrastructure).The number of publications,journal distribution,authors,publishing institutions, research hotspots were studied,and visual analysis was conducted.The research results indicate that the number of publications has shown a fluctuating and increasing trend in the past 10 years.The three hot topics in research on urban-rural integration development are urban-rural integration, urban-rural relations,and digital economy.The research process is as follows: the period from 2015 to 2017 was the initial stage,focusing on the issues in the integrated development of urban and rural areas. From 2018 to 2019 is a period of rapid development,focusing on solving problems in the integration of urban and rural development.From 2020 to 2024, in order to consolidate and deepen the stage,we will explore the internal driving mechanism of urban-rural integration development and new paths and methods to assist in urban-rural integration development. Future research should focus on enriching interdisciplinary perspectives, innovating and applying evaluation indicators,driving digital innovation, and guiding policies to better promote coordinated development and common prosperity between urban and rural areas.

Dynamic mechanism is an important direction, core and focus of building an important talent center and innovation highland in the world. The dynamic mechanism analysis framework of the world’s important talent centers and innovation highlands was conducted based on the push-pull theory, and reveals that the world’s important talent centers and innovation highlands are affected by three forces: push, pull and resistance. Based on the data of 40 countries from 2013 to 2021, the impact of population development on talent centers and innovation highlands was explored from the perspective of population. From the global perspective, the talent center and innovation highland show a trend of “strong west and weak east”, concentrated in North America and European countries, but the eastern countries began to rise, showing a trend of “rising east and falling west”. Population size will significantly positively affect the construction of the world’s important talent centers and innovation highlands. Population size has a significant positive impact on the construction of talent centers in high-income countries and the construction of innovation highlands in high-income countries. Population size has a significant negative impact on the construction of the world innovation highland in high-income countries. Finally, suggestions are put forward to give full play to the advantages of population, improve the overall quality of talents, gather international top talents and stimulate the vitality of talent innovation to promote the construction of China’s talent center and innovation highland.

As China’s emission reduction efforts continue to advance, the carbon emissions of the chemical industry have shown a gradual downward trend. However, the industry still faces challenges of high energy consumption and high carbon emissions in achieving the carbon neutrality goal. A system dynamics-based carbon emission model was constructed to simulate the carbon emissions of chemical sub-industries from 2010 to 2021.Dynamic effects of factors such as per capita consumption, fixed asset investment, and education level on carbon emissions were analyzed. The simulation results indicate that an increase in consumption levels may put pressure on carbon emissions, but significant reductions can be achieved through increased investment in fixed assets and promotion of green consumption behavior.

The impact of digital economy on the common prosperity of urban and rural areas was empirically examined by using inter-provincial panel data from 2012 to 2022.It is found that the development of the digital economy can significantly improve the level of common prosperity between urban and rural areas through multiple channels. The increase in government intervention and regional industrial agglomeration has a significant positive moderating effect on this process. The digital economy also promotes common prosperity between urban and rural areas by improving the allocation of labor resources. In heterogeneity analysis, it was found that there are significant differences in spatial distance, income, and policies regarding the promotion of shared prosperity between urban and rural areas by the digital economy. When using spatial spillover effects to test the exogeneity of instrumental variables, it is found that the level of digital economy in each province has no significant spillover effect on its surrounding provinces.

Value co-creation in the innovation ecosystem, as a result of the joint action of multiple subjects, is an important way for high-quality and sustainable development of enterprises. The existing studies mostly analyze the related problems from the level of single attribute of the subject, and seldom explore the antecedent mechanism of value co-creation from the perspective of multiple attributes of subjects, i.e., multi-dimensional proximity. To this end, structural equation modeling was used to investigate the impact of multi-dimensional proximity on value co-creation in innovation ecosystems and analyze the mediating role of knowledge search by studying the innovation activities of high-tech enterprises. It is found that multi-dimensional proximity positively affects innovation ecosystem value co-creation, knowledge search plays a mediating role in this process.
