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.

Digital transformation is an important way to enhance enterprise resilience. Taking Shanghai and Shenzhen A-share listed companies as the research object, the data from 2011 to 2021 were selected, and the research findings were found by empirical test. Enterprises’ digital transformation can significantly improve enterprise resilience, and this conclusion is still valid after a variety of robustness and endogenous tests. Among them, innovation efficiency and innovation quality play a part of intermediary role in the impact. In order to better enhance the resilience of enterprises and enable enterprises to achieve sustainable development, enterprises should further strengthen digital construction and attach importance to the improvement of innovation ability.

The results show that financial sharing informatization can effectively promote the improvement of financial management efficiency, the reduction of operating costs, and the enhancement of risk control. Appropriate basic references and theoretical guidance are proposed to provide certain assistance for the construction of financial shared service centers in enterprise groups.

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.

The 21st century is an era of explosive development of data information, and data is filled with the whole field of society. In the field of public service, the research of public service digital transformation is gradually favored by the theoretical and academic circles. Influenced by the inevitable trend of digitization of public services, the spillover effect of standardization, and the integration of digital information, it has become urgent to think about how to construct the mechanism of digital transformation and upgrading of public services. however, the digital transformation of public service has the constraints of supply mode, supply layout and supply diffusion, which makes the digital upgrading of service deeply hindered. this paper takes “service trial”, “service diffusion” and “service acceptance” as the analysis frame. focus on the digital transformation of high-quality public services, from the transport of digital service resources, distribution and quantitative control of facilities; top-down and bottom-up service diffusion paths; strengthen the effectiveness evaluation of digital services. in order to break the barriers of digital transformation and upgrading of public services, promote the connection between digital transformation and high-quality development of services, and help the in-depth advancement of chinese-style modernization.

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.

In the digital economy era, online markets are crucial venues for resource allocation, and optimizing resource allocation is a vital pathway to promote industrial transformation and upgrading. Based a two-way fixed effects model, a mediation effect model and a threshold effect model, the impact and underlying mechanisms of the development of online markets on the optimization of industrial structure in China were analyzed, using data from 288 prefecture-level cities from 2014 to 2021.It is found that the development of online markets significantly enhances the advancement of industrial structure but somewhat inhibits the rationalization of industrial structure. These conclusions remain robust after a series of robustness checks. The mediation effect test results show that the development of online markets can promote the advancement of industrial structure by improving resource allocation efficiency. Further analysis indicates that the promotion of industrial structure advancement by online markets exhibits heterogeneity, being more significant in the eastern and western regions, in areas with larger populations, and in regions with lower levels of digital infrastructure. The threshold model results reveal a marginally increasing nonlinear characteristic in the promotion of industrial structure advancement by the development of online markets. Therefore, to fully leverage the resource allocation role of online markets, it is necessary to further expand the scale of online markets, regulate their operations, define the boundaries of different types of online markets, strengthen market access reviews, enhance the role of data mechanisms, and bolster anti-monopoly and market supervision to encourage more participants. Different regions should be encouraged to adopt differentiated strategies for online market development.

In recent years, standard essential patents (SEPs) have garnered widespread attention. The potential future competitive risks associated with SEPs was preemptively assessed to provide a reference for industrial and enterprise development. First, the metrological characteristics of SEPs are summarized. Then, patents families were analyzed from 2014 to 2023 that at least an application in the family was granted by one of the five major Patent offices (IP5 offices), key innovative entities and key technological fields were identified in the study. The research finds that SEPs are characterized by concentration among holders, large family sizes, a large number of claims, and high citation frequencies. The main competition for SEPs in the coming period will still be concentrated in the electronics and communications fields. Furthermore, with the development of the Internet of Things era, various application scenarios related fields may also become battlegrounds for SEP competition, which should be monitored closely and appropriate risk prevention measures taken.
