Long-term costs and benefits analysis of China’s low-carbon policies

China’s long-term,low-emission development goals will hinge on effective low-carbon policies.Therefore,it is valuable to evaluate the costs and benefits of low-carbon policy packages to ensure that low-carbon development concepts and strategies can be well integrated into the policy making process.This work uses the Low-carbon Policy Assessment(LPA)model to assess long-term costs and benefits of climate and energy policies in China under the reference(RS)scenario and the low-carbon(LC)scenario,which includes 25 additional climate and energy policies.In the LC scenario,both energy-related CO2 emissions and total greenhouse gas(GHG)emissions peak around 2030,achieving China’s Nationally Determined Contribution(NDC)target.Of the policies included in the LC scenario,the five with the highest GHG mitigation potential beyond China’s existing policies are:fluorinated gas(F-gas)substitution,a renewable portfolio standard,carbon pricing,carbon capture utilization and storage(CCUS),and a fuel economy standard for heavy duty vehicles(HDVs).In addition to reducing GHG emissions,these policies decrease particulate emissions and associated premature deaths,which would otherwise reduce China’s GDP by nearly 1.5%in 2050.Together,these policies have the potential to promote significant low-carbon prosperity in China.

Research on the transmission mechanism of low-carbon policies:an empirical study of agricultural companies

Companies bear primary responsibility for low-carbon economy,thus relevant low-carbon policies should be set properly to guide them and to ensure their low-carbon production effectively.To solve the problems generated during low-carbon development,this article verifies the existence of the transmission path and strength.This verification includes mediating variables of companies'willingness and capacity to conduct low-carbon production,a transmission mechanism through incentive path and resources protection,and questionnaire data of agricultural companies.Conclusions show that the lowcarbon policies have obvious positive effects on willingness of corporation;the basic service-oriented policy has a significantly promoting effect on low-carbon production capacity;and low-carbon production performance is positively influenced by willingness as well as capability.Aiming at a better transmission path,some corresponding recommendations have been put forward in the end.

Automatic Generation of Attribute-Based Access Control Policies from Natural Language Documents

In response to the challenges of generating Attribute-Based Access Control(ABAC)policies,this paper proposes a deep learning-based method to automatically generate ABAC policies from natural language documents.This method is aimed at organizations such as companies and schools that are transitioning from traditional access control models to the ABAC model.The manual retrieval and analysis involved in this transition are inefficient,prone to errors,and costly.Most organizations have high-level specifications defined for security policies that include a set of access control policies,which often exist in the form of natural language documents.Utilizing this rich source of information,our method effectively identifies and extracts the necessary attributes and rules for access control from natural language documents,thereby constructing and optimizing access control policies.This work transforms the problem of policy automation generation into two tasks:extraction of access control statements andmining of access control attributes.First,the Chat General Language Model(ChatGLM)isemployed to extract access control-related statements from a wide range of natural language documents by constructing unique prompts and leveraging the model’s In-Context Learning to contextualize the statements.Then,the Iterated Dilated-Convolutions-Conditional Random Field(ID-CNN-CRF)model is used to annotate access control attributes within these extracted statements,including subject attributes,object attributes,and action attributes,thus reassembling new access control policies.Experimental results show that our method,compared to baseline methods,achieved the highest F1 score of 0.961,confirming the model’s effectiveness and accuracy.

Dynamic evaluation of digital and green development policies based on text mining of the PMC framework

Aiming to identify policy topics and their evolutionary logic that enhance the digital and green development(dual development)of traditional manufacturing enterprises,address weaknesses in current policies,and provide resources for refining dual development policies,a total of 15954 dual development-related policies issued by national and various departmental authorities in China from January 2000 to August 2023 were analyzed.Based on topic modeling techniques and the policy modeling consistency(PMC)framework,the evolution of policy topics was visualized,and a dynamic assessment of the policies was conducted.The results show that the digital and green development policy framework is progressively refined,and the governance philosophy shifts from a“regulatory government”paradigm to a“service-oriented government”.The support pattern evolves from“dispersed matching”to“integrated symbiosis”.However,there are still significant deficiencies in departmental cooperation,balanced measures,coordinated links,and multi-stakeholder participation.Future policy improvements should,therefore,focus on guiding multi-stakeholder participation,enhancing public demand orientation,and addressing the entire value chain.These steps aim to create an open and shared digital industry ecosystem to promote the coordinated dual development of traditional manufacturing enterprises.

Does Financial Globalization Discipline Macroeconomic Policies

Using the unbalanced panel data of 160 countries from 1970 to 2007,we employ inflation and the budget deficit as proxies for monetary policy and fiscal policy,respectively,and study whether financial globalization has discipline effects on these macroeconomic policies.The empirical results in our study suggest a significant discipline effect of financial globalization on monetary policy during the entire sample period,which is robust both to de jure and to de facto measures of financial openness.Our sub-sample investigations demonstrate that financial globalization reduces inflation only in higher-middle-income and high-income countries,and when financial globalization is scaled by the proportion of a country’s foreign assets and liabilities to its GDP,the discipline is evident only after 1988.Nevertheless,we do not demonstrate any evidence of financial globalization’s discipline effect on fiscal policy.The empirical results indicate that financial globalization even increases the budget deficit in certain countries and periods.

Analyzing Disaster Mitigation Policies in Japan and China from an Eco-DRR Perspective:A Comparative Study of Shanghai and Tokyo

Global climate change-induced natural disasters require international efforts and the adoption of Eco-Disaster Risk Reduction(Eco-DRR)policies for sustainable development.This study examines the status of Eco-DRR in disaster prevention policies through word cloud analysis,providing insights for policymakers to enhance disaster prevention amid increasing climate-related challenges.Tokyo and Japan prioritize soft aspects,while Shanghai and China emphasize engineering for flood prevention,revealing a gap in Eco-DRR application.Despite these differing approaches,the shared focus on water-related disasters indicates a shift towards urban resilience.Future research should assess policy effectiveness and the impact of Eco-DRR on disaster risk reduction and ecosystem protection.

The Way to Optimize the Right to Personal Data Portability in Chinese Practice——Based on Empirical Analysis of the Privacy Policies of 66 Mobile Apps

Although the existing legal norms and judicial practic-es can provide basic guidance for the right to personal data portabili-ty, it can be concluded that there are obstacles to the realization of this right through empirical research of the privacy policies of 66 mobile apps, such as whether they have stipulations on the right to personal data portability, whether they are able to derive copies of personal in-formation automatically, whether there are textual examples, whether ID verification is required, whether the copied documents are encrypt-ed, and whether the scope of personal information involved is consis-tent. This gap in practice, on the one hand, reflects the misunderstand-ing of the right to personal data portability, and on the other hand, is a result of the negative externalities, practical costs and technical lim-itations of the right to personal data portability. Based on rethinking the right to data portability, we can somehow solve practical problems concerning the right to personal data portability through multiple measures such as promoting the fulfillment of this right by legislation, optimizing technology-oriented operations, refining response process mechanisms, and enhancing system interoperability.

Combinations of Transportation Policies to Promote BRT Usage Using Artificial Society Model

Various transportation systems have been developed in recent years.In this study,an artificial society model is developed to examine the combination of transportation policies in urban areas.In this model,each trip maker selects the primary and terminal transportation modes.An artificial society model is applied to the southeastern region of Osaka City,Japan.The effects of introducing BRT(bus rapid transit,primary transportation)and on-demand buses(terminal transportation)are investigated.The results confirm that BRT is used by a certain number of users.An increase in the use of BRT will increase the amount of walking,thus resulting in a healthy city.However,on-demand buses are rarely used as terminal transportation.Additionally,the development of bicycle parking stations near BRT stops is shown to be effective in the northern section of the BRT route.

The role of land as the central piece to sustainable food systems:Lessons learned from Portugal national food-related policies

This paper discusses to what extent land is considered in food-related policies from a systemic perspective.Based on existing literature and international agendas priorities,we argue that access to and preservation of land for food along the food chain play a major role in sustainable food systems.To further explore this argument,we address the following question:Where does land stand in sectorial and national food-related policies?The mul-tiple dimensions and implications of food systems and the international agenda’s priorities namely the“Right to adequate Food”,“Food Sovereignty”and the“Right to Land”,were used as our conceptual framework.To work out how land is being considered in food sectorial policies,both quantitative and qualitative methods were applied to examine ten Portuguese national food-related policies.Results are showing a lack of consideration for land access and land preservation,needed all along the food chain to build a national sustainable food system.On the other hand,there is a gap between current grassroots priorities international agendas and food-related national policies.Such a situation strongly suggests that building a sustainable food system needs a clear food territorial perspective,still neglected,and shifting from sectorial policies towards a more integrated food system approach,that will include land as a central piece.

Asymmetric nexus between commercial policies and consumption‑based carbon emissions:new evidence from Pakistan

The current study extends the previous literature by exploring the effects of a newly discovered driver,i.e.,import taxes(as a proxy for commercial policies),on the consumption-based carbon emissions(CCO2e)for 1990Q1-2017Q4.For empirical analysis,several tests and methods,including Augmented Dickey–Fuller unit root test,Zivot–Andrews unit root test,asymmetric cointegration bound testing approach,non-linear ARDL,Wald-test,Granger causality test and wavelet quantile correlation(WQC)method are utilized.Furthermore,NARDL technique estimates reveal that contractionary commercial policy enhances the environmental quality by disrupting the detrimental effects of CCO2e.However,expansionary commercial policy escalates the environmental pollution by boosting the carbon emissions.Also,the exports and the renewable energy improve the ecological quality;however,GDP deteriorates the atmospheric quality by increasing the CCO2e.Besides,WQC method and the trivariate Granger causality test are deployed to confirm the robustness of the results.Based on the findings,some crucial policies are also recommended for sustainable and green development in Pakistan.

Exploring the effect of a low-carbon city pilot policies on carbon dioxide emission intensity:Based on the PSM-DID method

In 2010,the National Development and Reform Commission launched the low-carbon city(LCC)pilot pro‐gram.The scope of the pilot program was then gradually expanded to address the dilemma concerning eco‐nomic development and low-carbon transition.Selecting the second batch of LCCs in China,this study uses a combination of propensity score matching and difference-in-differences models to determine the effect of LCC pilot policies on CO_(2) emission intensity.We also used the mediation effect model to further investigate its in‐ternal mechanism.The findings of the study are as follows.First,the LCC pilot policy plays an important role in reducing carbon emissions.Second,LCC pilots policies reduce CO_(2) emissions through intermediary paths of output adjustment and technological innovation.Third,our heterogeneity analysis reveals that cities with higher levels of economic growth and better levels of human capital have superior carbon emission reduction effects;lastly,non-resource-based cities have better carbon emission reduction effects.

Factors Influencing Employees on Compliance with Cybersecurity Policies and Their Implications for Protection of Information and Technology Assets in Saudi Arabia

In the current digital era, it is difficult to preserve the confidentiality, integrity, and availability of an organization’s information and technology assets against cyber attacks. Organizations cannot rely solely on technical solutions for defense, since many cyber attacks attempt to exploit non-technical vulnerabilities such as how well employees comply with the organization’s cybersecurity policies. This study surveyed 245 randomly selected employees of government organizations in the Kingdom of Saudi Arabia with an electronically distributed questionnaire about factors that influence employees’ compliance with cybersecurity policies. The study found that ethical factors had the most influence on employee compliance with cybersecurity policies, followed in decreasing order of influence by legislative factors, technical factors, and administrative factors.

THE OPTIMAL DEDUCTIBLE AND COVERAGE IN INSURANCE CONTRACTS AND EQUILIBRIUM RISK SHARING POLICIES

In this paper, we consider the optimal risk sharing problem between two parties in the insurance business: the insurer and the insured. The risk is allocated between the insurer and the insured by setting a deductible and coverage in the insurance contract. We obtain the optimal deductible and coverage by considering the expected product of the two parties' utilities of terminal wealth according to stochastic optimal control theory. An equilibrium policy is also derived for when there are both a deductible and coverage;this is done by modelling the problem as a stochastic game in a continuous-time framework. A numerical example is provided to illustrate the results of the paper.
