As one of the sectors most sensitive to climate change, agricultural production activities are deeply affected by the negative impacts of environmental degradation. The implementation of “carbon peaking” and “carbon neutrality” policies will inevitably affect agricultural production methods and export trade. The impact of carbon emission reduction policies on agricultural exports was studied by selecting HS four-digit agricultural products from 2000 to 2021, using the Difference-in-Differences (DID) method for empirical analysis, and the mechanism of how carbon emission reduction policies affect agricultural export growth was explored. The research findings are as follows. The implementation of carbon emission reduction policies promotes agricultural export growth. In terms of heterogeneity, the implementation of carbon emission reduction policies has a relatively significant impact on the exports of grain and oil products, while the impact on meat exports is slightly smaller. In terms of moderating effects, labor, government support for agriculture, and climate change all play a positive role in promoting agricultural export growth through carbon emission reduction policies. Based on these conclusions, insights and suggestions are provided for the changes in China’s agricultural exports in the global agricultural market under the “dual carbon” goals.

To cultivate new-quality productivity scientifically and effectively, it is necessary to understand what “new-quality productivity”is and how to cultivate it in accordance with local conditions. Through a case study of the innovative development of the high-end intelligent equipment industry in Shaoxing City, it is found that new-quality productivity can be comprehensively and effectively cultivated from five perspectives, such as intelligent sensing power, strategic planning power, innovation promotion power, characteristic development power and shared cooperation power. This research and cultivation approach can provide certain inspiration and reference for a deeper and broader understanding and cultivation actions of new-quality productivity.

Under the background of a new development pattern, based on the five dimensions of innovation driven, digital economy, industrial transformation, green development and open development, select the relevant data of 41 urban agglomerations in the Yangtze River Delta from 2011 to 2020.Through cluster analysis and visualization, reflecting the development level of new economic drivers in urban agglomerations from different dimensions, and then a panel data model was constructed, taking per capital GDP as the explanatory variable and the level of new economic drivers as the explanatory variable, to explore the marginal impact of new economic momentum on economic growth in the Yangtze River Delta region. Finally, some constructive suggestions are put forward from the perspective of high-quality regional economic development.

Major science and technology projects enlisting and leading, as a new organizational and management approach to tackling key core technologies, is gradually becoming an important mechanism for promoting technological innovation and stimulating industrial vitality. The concept of the major science and technology projects enlisting and leading was firstly explained. Then, using the practice of Zhejiang’s major science and technology projects as a typical case, the top-level design, operational models and key initiatives were reviewed. Finally, suggestions such as strengthening the top-level design in multiple dimensions are summarized and put forward from the perspective of integration and innovation, deepening the application of horse racing mode and reward mode, and mobilizing the enthusiasm of leading backbone enterprises and other diversified innovation subjects, so as to ensure the effective implementation of major science and technology projects enlisting and leading, which can provide reference for optimizing the establishment, organization and management of major scientific and technological projects and improving the efficiency of scientific research organizations.

Marine tourism is a characteristic brand of Guangdong tourism,as well as one of the pillar industries of Marine economy in Guangdong Province. Based on the research of industry chain, the relevant standards of the Classification of Marine and Related Industries (GB/T20794—2021) and the Statistical Classification of National Tourism and Related Industries (2018) were combined, the Marine tourism industry chain was sorted out, the marine tourism industry chain and various industry segments in Guangdong Province synchronously were analyzed. The results show that the marine tourism industry chain in Guangdong is relatively complete, all aspects are involved. There are still insufficient in the cultivation of marine tourism formats, weaknesses in the manufacturing of facilities and equipment, and imperfections in training and leasing of marine tourism services in Guangdong’s marine tourism industry chain at present.

In the context of “rural revitalization” and the “dual carbon” goals, sustainable agricultural development has become an important issue and a necessary path for the development of “agriculture, rural areas, and farmers”. Based on agricultural insurance data from 11 provinces and cities along the Yangtze River Economic Belt from 2010 to 2020, the entropy method was used to measure the level of sustainable agricultural development and the impact of agricultural insurance on sustainable agricultural development and its mechanism were estimated through a fixed effects model. The results show that the level of sustainable agricultural development in various provinces and cities along the Yangtze River Economic Belt has increased significantly, with the upper reaches of the Yangtze River showing a higher increase in recent years than other provinces, indicating significant achievements in “source governance”. Benefiting from agricultural technological innovation, Shanghai has a much higher level of sustainable development than other areas downstream of the Yangtze River. Agricultural insurance can positively regulate the level of sustainable agricultural development through adjustments in production structure and factor input.

From the aspects of innovation subject, innovation carrier, innovation elements and innovation environment, combs the current situation of innovation resources gathering in Tsukuba Science City was combed, and the process and characteristics of innovation resources gathering in Tsukuba Science City was analyzed from the micro perspective through detailed historical data collection and sorting. Based on the different development stages of Tsukuba Science City, the state led compulsory agglomeration mode of innovation resources, the spontaneous agglomeration mode of innovation resources driven by industry university research cooperation, and the agglomeration mode driven by collaborative innovation platform and innovation chain construction were provided. It is pointed out that Tsukuba Science City is evolving in two directions, such as the construction of innovation ecosystem and the development of high-tech and sophisticated industries. Finally, some experiences are put forward for Xiong’an New Area to learn from, such as attaching importance to the construction of superior universities and colleges, building a cross regional and cross subject platform system, and increasing the openness of application scenarios.

A study on evaluating and forecasting the demand for tourism accommodation facilities in Jinan Citywas conducted. Data was crawled from platforms such as Ctrip, GoWhere.com, and Meituan using Python crawler technology. The LDA topic model was applied to uncover the latent thematic structure within the text data, enabling effective classification of accommodation place labels. Machine learning methods, including XGBoost, CatBoost, LightGBM, and RandomForest, were used to screen the core indicators that affect the ratings of lodging places. An evaluation system was constructed by combining the hierarchical analysis method (AHP) and the entropy weighting method to determine weights. Visual analysis was performed to reveal differences in reception capacity across various themes, accommodation types and areas, as well as proximity to transportation, business districts, schools and scenic spots. Suggestions for optimization are proposed based on the hotel’s theme, rating distribution, geographic location, review count and price, aiming to enhance service quality and supervision, thereby increasing reception capacity and user satisfaction.

Based on the deep cutting landslide treatment project in Caixi Township, PLAXIS 3D was used to establish a slope model with complex cracks under rainfall conditions, and the existence of cracks and the slope deformation stability under different fissure depths were analyzed. The result shows that the sliding surface of the slope changes significantly with increasing fissure depth. When the crack depth is close to the potential sliding surface, the crack divides the landslide into two separate parts, one is the crack surface itself and the other is the original sliding surface below the crack. This segmentation effect leads in a significant reduction in the slope stability. It is further found that there is a threshold effect between the crack depth and the slope stability, that is, the slope stability does not change much before the crack depth reaches a certain critical value. When the crack depth exceeds this critical value, the slope stability will decrease sharply. It reveals the influence mechanism of fissure on slope stability, in order to provide a scientific basis for slope engineering design, disaster prevention and treatment.
