Research on the development mode of cultural tourism industry based on the concept of low carbon and environmental protection by big data analysis

Abstract In order to build a low-carbon and environmentally friendly cultural tourism business, this research analyzes data on user characteristics, tourist attractions, and functional qualities. The clustering technique is used to examine the clustering features of the industry development, and the spatial variation characteristics of the industry development are developed with the aid of the closest neighbor index, standard ellipse, and kernel density estimation methods. In order to analyze the degree of development of this industry, the integration degree model was constructed by the entropy weighting method. The analysis shows that the growth rate of the central and western regions is 32.2% and 28.8%, respectively, while the growth rate of the eastern region is 22.7%. The integration degree of the eastern region ranges from 0.12 to 0.85, the integration degree of the western region ranges from 0.18 to 0.9, and the integration degree of the central region ranges from 0.2 to 0.8. Based on this study, the integration development of the low-carbon environmental protection concept and the cultural tourism industry is thriving.

Developing a low-carbon hybrid of ammonia fuel cell and internal combustion engine for carbon neutrality

With global warming and an increase in extreme weather, reducing carbon emissions in response to climate change has become a global consensus. Compared with traditional fuel vehicles, hybrid vehicles have the benefits of energy savings, low grid-load, and low emissions. The hybrid vehicles use the internal combustion engine and lithium-ion batteries as the hybrid power source to achieve the best match between the engine and the motor. However, the current commercial hybrid vehicle still has such defects as high dependence on fossil fuels, high carbon emissions, poor safety, etc. As such, it is necessary to explore and develop the next generation low-carbon hybrid vehicles. Herein, we propose a new-type hybrid of ammonia fuel cell and internal combustion engine with high-energy conversion efficiency and low-carbon emissions. Considering the advantages of low-carbon emissions, high mileage, fast refueling, low-cost, high-energy conversion efficiency, and high safety, a green low-carbon concept of the ammonia fuel cell-internal combustion engine hybrid vehicle (AFC-ICE HV) is proposed. This will help improve the scale and efficiency of China's green energy conversion, establish a green, low-carbon and sustainable economic system, provide new impetus for tackling climate change and environmental protection recovery, and help China and the world to achieve the Carbon Peak and Carbon Neutrality goal.

Study on the Application of Activity-Based Costing in Cold Chain Logistics Enterprises under Low Carbon Environment

Currently, a large amount of greenhouse gas emissions has caused a series of problems such as serious environmental degradation, and China is facing enormous pressure to reduce emissions. In terms of meeting the needs of people’s lives, cold chain logistics has undergone faster development, and its carbon emissions are relatively high. In response to the government’s advocacy for green and low-carbon concepts, some technical measures taken will increase the cost of carbon emissions. Identifying measures to reduce carbon emissions using management methods is an ongoing problem that this paper intends to solve. To address the shortcomings of the traditional cost method that cannot accurately account for the cost of each calculation object and ignores the carbon emission cost, this paper constructs an activity-based cost model for cold chain logistics enterprises to more comprehensively account for the operation cost and carbon emission cost. Then, a typical enterprise YS cold chain logistics company is used as a case study for an empirical calculation and analysis. The following conclusions are drawn: (1) the results identify the main activity centers that affect the operating costs and carbon emission costs of different customers; (2) a comparison among the total cost of each project helps to identify high-quality customers; (3) clarifying the carbon emission cost of wasting resources is beneficial for further optimizing the match between production capacity and business volume. This paper provides a path reference for enterprises to efficiently implement logistics cost management and carbon emission control, which can help enterprises cope with cost reduction and efficiency enhancement in a low-carbon environment and promote the long-term development of the logistics industry and environmental protection.

Waterfront City Management to Realize Low Carbon Landscape in Pekanbaru City, Indonesia

Poor regional spatial planning makes the lack of water catchment functions and green open spaces result in environmental problems, particularly in Pekanbaru City, Indonesia. The solution is to utilise the potential of the Siak River and its historical heritage through waterfront city (WFC) management. Structuring a WFC based on a low-carbon concept can solve environmental problems by significantly reducing carbon emissions. This study aims to inventory, map, and evaluate the condition of the existing landscape, analyse public perceptions, and develop recommendations for a WFC with a low-carbon landscape concept. The methods used are historic urban landscape analysis, spatial analysis with land evaluation, community perception, and the preparation of recommendations. The results showed that the management of historical and cultural heritage is still poor. Based on the evaluation of land suitability, the WFC area has the potential to develop tourism, settlement, conservation, and pond areas with varying degrees of suitability according to the function of the area and several limiting factors. Through public perception, the level of enthusiasm of respondents is very high for applying the low-carbon landscape concept. Recommendations are made with the 15-Minute City Strategy through zoning and management programmes, namely tourism, mixed-use, conservation, and cultural preservation.

Does the implementation of green finance regulation promote the high-quality development of enterprises? Evidence from a quasi-natural experiment in China.

The improvement of enterprise total factor productivity and labor productivity is the micro-embodiment of high-quality economic development. Green finance relies on the dual functions of resource allocation and environmental regulation to guide enterprises to adjust their mode of operation through incentive and restraint mechanisms, attach importance to energy conservation and environmental protection, and guide enterprises to develop with high quality. Taking the construction of the green financial supervision system in 2016 as a quasi-natural experiment, we constructed a difference-in-difference model to investigate the impact and mechanism of green finance on the high-quality development of enterprises, based on the panel data of Chinese A-share listed companies from 2006 to 2020. The results show that the implementation of green finance effectively promotes the high-quality development of enterprises. This promotion effect is heterogeneous from perspectives of enterprise-specific characteristics, executive education background, and environmental regulation intensity. The influence mechanisms mainly rely on tightening financial constraints, upgrading the level of green technology innovation, and improving the quality of internal control. These findings provide an important decision-making reference for better implementing green finance policies and promoting high-quality economic development under the green and low-carbon concept and carbon peak carbon neutrality goals.

Research on bike-sharing travel behavior: A review of the Chinese language literature

In recent years, with the development of information technology and the promotion of low-carbon concept, bike-sharing has gradually emerged in Chinese cities and become one of the daily travel modes for residents. Meanwhile, the research on bike-sharing travel behavior has become a hot topic in the field of urban transportation planning. However, due to the language barrier, relevant Chinese language literature is often neglected in the existing studies. To fill this gap, this paper provided a review of the Chinese literature that examines bike-sharing travel behaviors. Through bibliometric analysis, we found that recent papers in this area focused on the spatiotemporal characteristics, influencing factors and demand forecasting of bike-sharing trips. Further, we summarized the new data and methods adopted and the main findings obtained in these researches. In response to the current status of relevant studies, we concluded our insights on planning for a low-carbon cycling environment. Finally, we suggest that future directions should include the mining of socio-economic attributes of individual bike-sharing users, the influence of humanistic perception factors on bike-sharing trips, and the bike-sharing travel behavior in the post-pandemic era in China.

Recycling Ti3C2Tx Oxide Nanosheets through Channel Engineering: Implications for High-Capacity Supercapacitors

Channel (hole and interlayer) engineering on two-dimensional (2D) MXenes has been proven to be an effective strategy to solve the issues of congested ion transport pathways, limited active sites, and sluggish ion transport kinetics caused by restacking of MXene nanosheets, which extended the application in the field of energy storage. Herein, a simple channel engineering strategy was proposed to treat the long-term stored Ti3C2Tx nanosheets, resulting in formation of an interlayer-expanded holey Ti3C2Tx film via etching out Ti3C2Tx oxides. The in situ oxides expanded the interlayer spacing and created holes on the Ti3C2Tx nanosheets, which formed channels in all directions. The interlayer-expanded holey Ti3C2Tx film showed outstanding electrochemical performance, with both high capacity (448 F g–1 at 2 mV s–1) and good cyclic stability (95.3% retention after 5000 cycles). Importantly, this strategy effectively recycles the waste MXenes that are oxidized by long-term storage, which embodies the concept of low carbon and environmental protection and promotes the industrialization process of MXenes.

Application of renewable energy decorative materials in modern architectural design under low-carbon concept

Abstract The construction industry is booming, but construction projects will consume much non-renewable energy and cause environmental pollution. In response to this problem, this article establishes a low-carbon architectural design model and discusses the application of renewable energy decorative materials in modern architectural design in detail. Previous studies have shown that renewable energy decorative materials are widely used in ventilation design, thermal insulation design, interior design and lighting design, and the weights of carbon emissions in the use stage are 20%, 46%, 29% and 33%, respectively. In 2021, the usage weights of renewable energy decorative materials in ventilation design, thermal insulation design, interior design and lighting design will be 70%, 72%, 80% and 70%, respectively, far exceeding the usage of traditional materials.

The Inhibition and Equilibrium of Policy Effectiveness of the Low-Carbon Economy: Evidence from Liaoning Province of China.

Excessive emissions of carbon dioxide and other greenhouse gases have seriously affected the ecological environment, public health, and the normal operation of the social economy, and the development of the low-carbon economy has become an international consensus. The policy norms are one of the important factors affecting the development of the low-carbon economy; however, the implementation of low-carbon economic policy in many countries has been inhibited. This study chose Liaoning Province of China for the case study, and the policy system, the policy tools, the administrative system, the low-carbon technology, and the low-carbon concept are found to be factors that led to the inhibition of the policy effectiveness of the low-carbon economy in Liaoning Province. We applied the modified Schweller Neoclassical Realist Theory to establish a multi-factor linkage model to demonstrate the overall relationship among various variables. The results show that the equilibrium of policy effectiveness of the low-carbon economy in Liaoning Province depends on different permutations of variables. We also discussed the problems of the policy system, the policy tools, the administrative system, the low-carbon technology, and the low-carbon concept that lead to policy effectiveness inhibition, and used the economic method to set a special mathematical model for maximizing the equilibrium of policy effectiveness of the low-carbon economy in Liaoning Province. In response to the problems of the above factors, strategies to promote the development of the low-carbon economy in Liaoning Province are proposed. This study enriches the research on the policy effectiveness of the low-carbon economy in China and provides some inspiration for the goal of carbon neutrality and other developing countries with high carbon emissions.

Multi-objective integrated optimization study of prefabricated building projects introducing sustainable levels

As construction becomes greener, people have higher and higher requirements for engineering project management, which makes it necessary to deeply study the comprehensive optimization of schedule, cost and sustainability level. Adhering to the concept of low carbon and green, the article takes carbon emission factor into the total cost of building construction and improves the traditional cost objective of engineering projects; then quantitatively analyzes the economic, environmental and social impacts of assembled buildings from the perspective of sustainability, and introduces the sustainability objective into the traditional duration-cost problem study, taking the duration of each job in the double code arrow diagram as the independent variable to construct the duration -cost-sustainability level multi-objective optimization model. In order to solve the type effectively, a series of Pareto optimal solutions are obtained using the NSGA-II algorithm, and the efficacy coefficient method is used for program decision making. The results show that the Pareto solution set can provide effective support for the project manager’s decision making, and the NSGA-II algorithm is effective in solving the multi-objective optimization model.

Study on the Interaction Effect between the Intensity of Government Low-Carbon Subsidies and the Growth Ability of Green and Low-Carbon Emerging Enterprises.

With the development of science and technology and society, people's demand for a healthy living environment is increasing, and the expression "low carbon" has become a daily feature of people's lives. The emergence of a low-carbon economy, the impact on the traditional industrial structure and the formation of a new economic landscape make China, a developing country, eager to seize this opportunity to enhance its international competitiveness. To achieve this, it is necessary to establish a low-carbon concept, to actively restructure industrial and develop low-carbon industries; only in this way can we take advantage of the new round of industrial restructuring and grasp the initiative of development. Therefore, this paper selects data from enterprises in the emerging low-carbon industry, and uses a SVAR model to conduct a dynamic interaction analysis between government subsidy intensity, enterprise profitability, asset growth capacity and enterprise size. The results of the study show that the intensity of government subsidies in the first period has a certain positive effect on a company's current profitability and asset growth, the improvement being most significant on its profitability. Among the larger companies, asset growth and profitability in the first period had a significant positive impact on current earnings, and the contribution of profitability to the company's own performance was much larger than the average; among the smaller companies, asset growth and profitability in the first period had a significant positive impact on current earnings, and the contribution of asset growth to the company's own performance was much larger than the average. The intensity of prior government subsidies in the Highs group has a significant positive relationship with the intensity of current government subsidies, the firm's asset growth capacity and profitability; the intensity of prior government subsidies in the Lows group only has a significant positive impact on the asset growth capacity in the current period. In addition, the interaction between the three core variables in the Highs group is also significantly higher than that in the Lows group. This indicates that the government should implement differential policies and financial subsidies according to the actual needs of enterprises to maximize the effect of capital use and promote the development and growth of emerging enterprises.

Discussion on key technologies of big data in financial budget performance management in low-carbon economy

Reducing energy consumption, pollution and waste emissions are the basic elements of the concept of low-carbon economy. There is an inseparable link between low-carbon economy and financial work in enterprises. In terms of financial work, it is an indispensable element in the development of enterprises. In order to help enterprises improve their financial performance with pertinence, comparability and applicability, this paper selects clear enterprise performance evaluation indicators for analysis from the financial perspective. It aims to help enterprises save energy in a low-carbon economic environment. In this study, the performance evaluation system and financial allocation method of Anhui enterprises’ financial expenditure are studied. In the empirical analysis, 10 ordinary enterprise undergraduate colleges in Anhui Province are selected as samples. This model covers the performance evaluation scope of most financial expenditures of general enterprises in Anhui Province, and is analyzed in the process of DEA model analysis. In the process of DEA model analysis, it can better explain the input-output performance of Anhui enterprises. In this paper, financial expenditure performance evaluation indicators designed based on principal component analysis, data envelopment analysis and other analysis methods can focus on reflecting the input and output of enterprises. It can realize the standardization of evaluation results and better compare the efficiency of financial capital expenditure between enterprises. In other words, the concept of low carbon in enterprises has given a certain standard for the development of financial work. The financial department of the enterprise must fully implement the concept of low carbon during the budget period. Only in this way can we effectively promote the development of enterprises towards low-carbon and environmental protection. Finally, it will lay a solid foundation for the sustainable development of the enterprise.

A Methodological Study on the Design Defending Baffles Based on Mangrove Bionics

In terms of the failure of giving considerations to both aesthetic ornamental and low-carbon function for the current disaster prevention and mitigation engineering. This study proposes the debris-disaster prevention baffles applicable to natural scenic areas which designed based on mangroves properties, to solve this problem by adopting bionic design method. The research methodology is as follows: (1) To propose a Six Elements and Ten Steps Design Method for extracting the critical bionic elements of mangrove plants that contributes to the prevention of winds and waves. (2) To construct a decision objective model based on the Analytic Hierarchy Process method (AHP). Prioritize the critical bionic design elements and build a geometric structure model. (3) To compare the disaster mitigation performance through numerical simulations, and thus select an optimal one for further studies. (4) To design the final disaster prevention product based on the above theoretical guidance, low-carbon concept, efficient protection orientation, and environment-friendly principles. This study indicates that the use of bionic design satisfies aesthetic ornamental, and low-carbon demands. The appliance of AHP avoids subjective one-sidedness in design process when considering the priority of bionic elements. The numerical simulation experiments adopted in this study aim to compare the blocking effect of different baffle models and achieve the optimization the performance in disaster prevention of traditional baffle groups. In this study, the bionic product design methodology is adopted for baffle design to solve existing aesthetic and environmental problems. The particle accumulation mass after the new baffles can be effectively reduced by 2–3 times compared to the traditional baffles. Furthermore, the new baffle is more aesthetically pleasing than the traditional ones.

Carbon emission reduction effect of China's low-carbon energy transition policy: An empirical analysis based on policy quantification

To better address climate change and environmental pollution, it is of great practical significance to comprehensively evaluate the impact of low-carbon energy transition policies on carbon emission reduction. This paper conducts a policy quantitative evaluation of low-carbon energy transition policies from three dimensions: policy intensity, policy objective, and policy instrument. On this basis, the ridge regression model is used to analyze the carbon emission reduction effect of policies. The results show that (1) changes in policy quantities mainly cause the evolution of total policy effectiveness. The government's emphasis on low-carbon energy transition has fluctuated. (2) The two policy objectives of optimizing the use of fossil energy and developing a low-carbon concept are less synergistic with other policy objectives and neither has a significant impact on carbon reduction. (3) The government prefers to adopt command control policy instruments, but their actual carbon emission reduction effects are inferior to that of economic incentive policy instruments. These findings can provide a decision-making basis for the government to further formulate and optimize policies.

Urban Growth Boundaries Delineation under Multi-Objective Constraints from the Perspective of Humanism and Low-Carbon Concept

Urban growth boundaries (UGBs) play an important role in controlling urban sprawl and protecting natural ecosystems. Traditional methods mainly focus on the heterogeneity of regional resources and environment rather than residents’ behavioral activities. However, residents’ behavioral activities are one of the most important factors influencing urban spatial form. Fortunately, the emergence of big data, especially phone signaling data, provides alternative data sources to understand the dynamic resident behavior activity space, which is significant for people-oriented urban development. Therefore, we propose a novel framework for UGB delineation based on multi-source big data and multi-objective constraints, which emphasizes humanism and the low-carbon concept in urban expansion simulation. The multi-objective constraints are constructed from the evaluation of resident activity space expansion potential, the evaluation of urban construction suitability, the evaluation of ecological conservation importance, and the human survival materials limitation. We apply the framework to Ningbo, and the results show that the framework under multi-objective constraints from a people-oriented and low-carbon perspective is more reliable and comprehensive than that without constraints. The findings also show that the UGB delineation based on multi-source big data has higher accuracy and better performance. The conceptual and methodological advances of this study are also applicable to other cities to help UGBs delineation.

Ethical Construction and Development of Mining Engineering Based on the Safe, Efficient, Green, and Low-Carbon Concept

Modern mining engineering has become a huge system project with the increased intensification and complexity of mining engineering, which interwinds, involving many factors. Ethical issues in the main body of mining engineering have become more and more prominent. What must complement ongoing discussions is a more professional and systematic analysis that engages with mining engineering on the socio-technical systems. In this paper, first, the connotation and basic principles of mining engineering ethics are put forward. Then, the ethical responsibilities that mining engineers may face are analyzed. It is suggested that the code of mining engineering ethics can, in practice, provide engineers with the necessary guidelines to avoid mine accidents caused by wrong decisions. In addition, a case base is introduced to train students to analyze engineering ethics in practical cases, and four typical case studies are discussed in detail. Then, the implementation paths of mining engineering ethics are studied, which are centered on the concept of safe, efficient, green, and low-carbon development. Finally, we suggest that improving the ethical norms of mining engineering, personnel training system, and moral supervision of mining projects will enable engineers to deal with the ethical issues of mining engineering more effectively, thereby improving the sustainability of mining engineering.

Development of an extended STIRPAT model to assess the driving factors of household carbon dioxide emissions in China

Although the past twenty years have witnessed China's remarkable economic development, the cost in terms of greenhouse gas emissions and a deteriorating environment has been enormous. Numerous studies have revealed the influence of household factors on household carbon dioxide emissions (HCEs) and called for a reduction of HCEs to mitigate climate change, but few have focused on assessing the most significant household driving factors of HCEs. Using statistical data between 2005 and 2019 in Jiangsu, China, this study developed an extended stochastic impact by regression on population, affluence, and technology (STIRPAT) model to assess the most significant driving factors of HCEs. The results show that the most significant driving factors are household size, total population, unemployment, and urbanisation rate. The study found that HCEs are positively impacted by household size while negatively impacted by the unemployment rate. Based on the study's findings, the following suggestions are proposed to lower HCEs: (i) establish an optimal consumption concept to guide residents towards consuming reasonably; (ii) cultivate a low-carbon concept among residents and promote low-carbon emissions living; and (iii) pay close attention to population structure factors and formulate effective measures accordingly. The study provides insightful information on the key driving factors of HCEs, which can facilitate achieving carbon emissions neutrality.
