The Loess Plateau is an important ecological zone in China. The changes in vegetation coverage were investigated in the Loess Plateau region from 2001 to2016, as well as the impacts of climatic factors and human activities on it. The result shows that the vegetation coverage in the Loess Plateau has generally exhibited an increasing trend, with a significant extension of the growing season. Overall, the vegetation coverage in the Loess Plateau has a weak or negative correlation with temperature, while it shows a positive correlation with precipitation. Among different land use types, the vegetation coverage of arable land, forest land and grassland has generally increased, whereas the vegetation coverage of water bodies, built-up areas and unused land has decreased overall.

Coastal ocean circulation models have improved dramatically in recent decades, but it is still difficult to obtain sufficient data to constrain and validate simulations. National Oceanic and Atmospheric Administration, hereinafter referred to as NOAA, in cooperation with local fishing vessels, provides a low-cost data observing system that has produced a large number of hourly bottom temperature datasets over a wide area of the US Northeast Continental Shelf over a wide area, generating a large number of hourly bottom temperature datasets. In order to provide a better validation of the coastal ocean circulation model and to help fishermen have a better understanding of the fishing conditions, three existing ocean models were combined and the hourly real-time bottom temperature data was used as a reference to visualize the data from each ocean model and the data from multiple ocean models after Bayesian model averaging, which revealed that the performance of the Bayesian combined model was better. The Bayesian combination model is found to perform better.

In order to sort out the research and development of carbon information disclosure in China, based on CNKI database and using bibliometric method and CiteSpace software, 321 core journal literatures collected by CNKI from 2010 to 2024 were visually analyzed from the aspects of annual publication volume, journal distribution, publishing institutions, research hotspots and research trends. The results show that the literature research on carbon information disclosure in China shows an increasing trend, but the degree of cooperation among high-yield authors in this field is not close, and the stable cooperative relationship between research institutions has not been formed. The research in this field mainly focuses on three aspects, such as carbon information disclosure system, influencing factors and economic consequences of carbon information disclosure, and quality evaluation of carbon information disclosure. Under the background of “dual carbon” goal, the construction of carbon information disclosure system combined with specific industries will be the future research direction.

With the issuance of a series of supportive policies and the rapid development of emerging technologies, the digital public service system is continuously being improved and optimized. Focusing on the actual development of Shandong Province's digital public service system, an evaluation index system for digital public service quality satisfaction that includes 4 criterion layers and 15 target layers was established. Through questionnaire surveys, a fuzzy comprehensive evaluation model was employed to quantitatively assess the quality of digital public services in Shandong Province, and a thorough analysis of the existing issues, particularly the deficiencies in service quality and service innovation was conducted. Based on this, targeted improvement strategies are proposed such as enhancing the timeliness of problem resolution, improving information transparency, strengthening multi-department service integration, providing personalized services, promoting intelligentization levels, and optimizing service processes, in order to effectively enhance the quality of digital public services in Shandong Province and meet the growing service demands of the public.

On the basis of constructing an evaluation index system for energy consumption and green development level, the entropy method, coupling coordination degree model, Dagum Gini coefficient and its decomposition were used to calculate the coupling coordination level of energy consumption and green development in 30 provinces(due to the lack of data, the statistical data mentioned here do not include the Tibet Autonomous Region, the Hong Kong Special Administrative Region, the Macao Special Administrative Region and Taiwan Province) of China from 2006 to 2021, and the regional differences in coupling coordination level among different regions were analyzed in depth. Research shows that the overall level of coupling and coordination between energy consumption and green development in China is on the rise, but the western region leads in energy consumption, while the eastern region leads in green development.The coupling coordination level between energy consumption and green development shows an increasing trend, with the overall level shifting from low coordination to moderate coordination, presenting a situation of “high in the east and low in the middle and west”. The overall difference in the coupling coordination between energy consumption and green development in the four major regions of East, Central, West and Northeast China is gradually narrowing, and the main source of the difference is regional differences. Reference is provided for promoting the deep integration of energy consumption and green development, and achieving the “dual carbon” goal.

In the context of globalization, the development of new quality productivity provides an important opportunity to enhance the innovation ability of enterprises and promote the internationalization of technical standards. Based on the theory of diffusion of innovation, a theoretical model of the impact of new quality productivity on the internationalization of technical standards was constructed, taking Chinese A-share manufacturing companies listed in 2010—2023 as the research sample. The empirical test finds that the enhancement of new quality productivity significantly contributes to the internationalization of enterprises’ technical standards. Global innovation network embedding plays a mediating role in it. It suggests that firms can accelerate the globalization of technology standards through cooperation and interaction with international innovation agents. This study reveals the influence path of new quality productivity to promote the internationalization of technical standards through global innovation network embeddedness, which further expands the application scope of innovation diffusion theory. Scientific guidance for enterprises is provided to promote the internationalization of technical standards, and is helpful to give full play to the intrinsic potential of new productivity.

The booming live streaming e-commerce has drawn a large number of consumers and businesses to participate. However, research on consumers’ impulse purchase willingness in live streaming is still in its infancy. Based on the SOR theory, from the perspective of consumers’ loss aversion psychology, a structural equation model was developed to analyze and validate the mechanism through which the live e-commerce atmosphere cues affected consumers’ inclination to make impulsive purchases. It is found that the live e-commerce atmosphere cues significantly affect consumers’ perceived risk and anticipated inaction regret. The mediating effect of perceived risk and anticipated regret of inaction is significant when it comes to the influence of live e-commerce atmosphere cues on willingness to make impulse purchases. In the context of live e-commerce, companies can adopt measures such as increasing product discounts, enhancing the visual appeal of the live broadcast room, and activating the atmosphere of the live broadcast room to strengthen the atmosphere cues in the context of live e-commerce, and make full use of consumers’ loss aversion to achieve promotional goals.

Based on the entropy method and the coupling coordination degree model, this paper the coordination degree of economic and water and land resources in Inner Mongolia Autonomous Region was calculated. It is found that the overall economic composite index of each banner county in Inner Mongolia shows an upward trend of varying degrees from 1990 to 2018, but there is spatial imbalance and increasing gap in regional economic development. The natural resources index shows an upward trend, but the increase is small, and the spatial difference of natural resources is relatively large and shows an increasing trend. Since 2005, the coordination degree of Inner Mongolia has shown an N-shape, indicating that the coordination between economic development and water and land resources has a positive trend.

In the construction of the Northeast Land Sea Corridor, it is an urgent need to enhance the driving force of Liaoning Province’s radiation belt towards the sea and land by leveraging the synergistic effect of the Liaoning Port Group. Taking six ports within the province as the research object, panel data from 2019 to 2022 were selected to evaluate the contribution of each port to the coordinated development of the port cluster using entropy weight method. The dynamic qualitive comparative analysis (QCA) method was used to find a feasible driving path to effectively promote the high level of coordinated development of the Liaoning port cluster. The results indicate that the level of coordinated development of ports is influenced by multiple conditional variables. There are three configuration paths that affect the level of coordinated development of ports, with potential substitution relationships between configurations and no significant time or individual effects found.

Airport economic demonstration zones are becoming the growth poles that drive regional high-quality development. Airport economic zones at different stages of development have heterogeneous needs for industrial structure adjustment. Exploring differentiated and coordinated adjustment strategies is of great significance for promoting airport economic development. Based on the life cycle theory, the development stages of national airport economic zones were divided, and the PVAR model and the coupling coordination degree model were constructed to explore the interaction and coordination degree between industrial structure adjustment and airport economic development. The results show that 8 of the national airport economic zones are in the initial stage, 9 are in the development stage, and 1 is in the mature stage. In the initial stage and mature stage, the upgrading and rationalization of industrial structure promote and hinder the high-quality development of airport economy respectively, but such promoting and hindering effects will gradually weaken in the long run, and the hindering effect may turn to promoting effect in the long run. For the mature airport economic zone, the upgrading of industrial structure will slowly promote the development in the long run. The rationalization of industrial structure will play a great role in promoting. The coupling coordination degree between industrial structure and airport economic development is generally increasing with the development of airport economy, and Nanning, Guiyang and Qingdao airport economic zones are on the verge of imbalance. In view of this, the airport economic zone should pay attention to the rationalization of industrial structure and selectively upgrade the industrial structure in the initial period and the development period, and can focus on the upgrading of industrial structure in the mature period.
