Remarkable achievements of the new energy industry policy framework over the past two decades Over the past two decades,the industry policy framework centered on the Renewable Energy Law has effectively facilitated the leapfrog development of China’s new energy sector.During this period,policy incentives were primarily focused on promoting the rational scaling of the industry,thereby driving rapid technological upgrades and iterations.This,in turn,enabled a significant reduc-tion in the cost of new energy power generation.In this process,policy played a pivotal role in two key areas:first,by providing per-kilowatt-hour subsidies to bridge the cost gap between new energy and conventional power sources;and second,by exempting the system cost of new energy grid-connected operation through a full guaranteed purchase system. 展开更多

The increasing complexity of on-orbit tasks imposes great demands on the flexible operation of space robotic arms, prompting the development of space robots from single-arm manipulation to multi-arm collaboration. In this paper, a combined approach of Learning from Demonstration (LfD) and Reinforcement Learning (RL) is proposed for space multi-arm collaborative skill learning. The combination effectively resolves the trade-off between learning efficiency and feasible solution in LfD, as well as the time-consuming pursuit of the optimal solution in RL. With the prior knowledge of LfD, space robotic arms can achieve efficient guided learning in high-dimensional state-action space. Specifically, an LfD approach with Probabilistic Movement Primitives (ProMP) is firstly utilized to encode and reproduce the demonstration actions, generating a distribution as the initialization of policy. Then in the RL stage, a Relative Entropy Policy Search (REPS) algorithm modified in continuous state-action space is employed for further policy improvement. More importantly, the learned behaviors can maintain and reflect the characteristics of demonstrations. In addition, a series of supplementary policy search mechanisms are designed to accelerate the exploration process. The effectiveness of the proposed method has been verified both theoretically and experimentally. Moreover, comparisons with state-of-the-art methods have confirmed the outperformance of the approach. 展开更多

Mandate-based and market-based mechanisms represent two primary approaches to achieving policy objectives,yet the debate over their relative effectiveness remains unresolved.The mandate-based approach is exemplified by pilot programs for low-carbon provinces and cities,referred to as“Low-Carbon Pilot Provinces/Cities”,while the market-based mechanism is reflected in pilot programs for carbon emissions trading markets,or“Carbon Trading Pilot Programs”.This paper employs event study analysis to compare the carbon emission reduction impacts of these two approaches.Our findings reveal that the Low-Carbon Pilot Provinces/Cities achieved emissions reduction primarily by curbing economic output,without significantly reducing carbon emissions intensity.In contrast,the Carbon Trading Pilot Programs led to an increase in total carbon emissions by driving economic growth,even as they reduced carbon emissions intensity.A heterogeneity analysis further indicates that the emissions reductions observed in the Low-Carbon Pilot Provinces/Cities were predominantly concentrated in economically less-developed regions,whereas the increase in carbon emissions associated with the Carbon Trading Pilot Programs was more significant in regions with lower initial carbon emissions intensity.Against the backdrop of China’s efforts to achieve its carbon peak and neutrality goals,this paper offers valuable insights for the design of effective climate policies. 展开更多

Exo-atmospheric vehicles are constrained by limited maneuverability,which leads to the contradiction between evasive maneuver and precision strike.To address the problem of Integrated Evasion and Impact(IEI)decision under multi-constraint conditions,a hierarchical intelligent decision-making method based on Deep Reinforcement Learning(DRL)was proposed.First,an intelligent decision-making framework of“DRL evasion decision”+“impact prediction guidance decision”was established:it takes the impact point deviation correction ability as the constraint and the maximum miss distance as the objective,and effectively solves the problem of poor decisionmaking effect caused by the large IEI decision space.Second,to solve the sparse reward problem faced by evasion decision-making,a hierarchical decision-making method consisting of maneuver timing decision and maneuver duration decision was proposed,and the corresponding Markov Decision Process(MDP)was designed.A detailed simulation experiment was designed to analyze the advantages and computational complexity of the proposed method.Simulation results show that the proposed model has good performance and low computational resource requirement.The minimum miss distance is 21.3 m under the condition of guaranteeing the impact point accuracy,and the single decision-making time is 4.086 ms on an STM32F407 single-chip microcomputer,which has engineering application value. 展开更多

As urbanization accelerates globally,air pollution-particularly PM_(2.5)-is becoming an increasingly significant threat,not only to public health but also the environment.In-depth research on the impact of China’s Zero Waste City pilot policy on PM_(2.5)concentration offers valuable insights into the policy’s effectiveness and provides a potential model for environmental governance worldwide.This study employs panel data from 293 Chinese cities from 2014 to 2022 to systematically analyze the impact of the Zero-Waste City policy on PM_(2.5)concentration using a difference-in-differences model.The findings indicate that the policy not only directly reduces PM_(2.5)concentration but also indirectly curbs PM_(2.5)emissions by enhancing green innovation and green economic efficiency.Moreover,the policy’s effects are found to be positively moderated by urban energy dependence and digital financial inclusion,while they are negatively moderated by the government debt ratio.Based on these findings,this study suggests that cities should actively develop their digital economy,reduce government debt,promote green innovation,and improve green economic efficiency,as doing so will enhance their implementation of environmental policies and promote sustainable urban development. 展开更多

Embodied visual exploration is critical for building intelligent visual agents. This paper presents the neural exploration with feature-based visual odometry and tracking-failure-reduction policy(Ne OR), a framework for embodied visual exploration that possesses the efficient exploration capabilities of deep reinforcement learning(DRL)-based exploration policies and leverages feature-based visual odometry(VO) for more accurate mapping and positioning results. An improved local policy is also proposed to reduce tracking failures of feature-based VO in weakly textured scenes through a refined multi-discrete action space, keyframe fusion, and an auxiliary task. The experimental results demonstrate that Ne OR has better mapping and positioning accuracy compared to other entirely learning-based exploration frameworks and improves the robustness of feature-based VO by significantly reducing tracking failures in weakly textured scenes. 展开更多

Purpose:This study examines the impact of research policy changes on scientific retractions of publications authored by Romanian authors,focusing on national trends and the interplay between policy reforms and publishing practices.Design/methodology/approach:Using data from the Retraction Watch Database and Web of Science(WoS),188 unique retractions involving Romanian authors(2000-2022)were analyzed.The study compared retraction patterns before and after the 2016 reforms,which prioritized the publication of articles in WoS-indexed journals over non-WoS outputs.Findings:The analysis identified two key trends:(1)before the 2016 reforms,retractions predominantly involved non-WoS journals(99 non-WoS retractions to 38 WoS retractions),a trend that reversed post-reform(16 non-WoS to 35 WoS),and(2)while the total number of WoS-indexed retractions increased after the reforms,the retraction rates for WoS articles remained stable.Post-reform reliance on MDPI journals,which have low retraction rates,partially explains this stability.Excluding MDPI publications,retraction rates for articles and reviews increase by 14.91%,aligning with patterns seen elsewhere.Research limitations:The study focuses on retractions involving Romanian authors,limiting its generalizability.Furthermore,reliance on database records may not fully capture all retractions.Practical implications:These findings underscore the need for research policy reforms to consider a broader range of effects,and the need for nuanced interpretations of retraction data,which are influenced by a complex range of factors,including specific publisher practices.Originality/value:This research is the first to investigate the complex relationship between research policy reforms,publisher behavior,and retraction trends. 展开更多

This paper systematically reviews the institutional evolution of the China-ASEAN Free Trade Area(CAFTA),from its inception in 2002 and full establishment in 2010,through the CAFTA 2.0 upgrade in 2015,to the substantive conclusion of CAFTA 3.0 negotiations in 2024.It highlights the key institutional innovations along this trajectory and examines the structural complementarities between China and ASEAN in terms of clean energy resources and industrial capabilities.Based on this foundation,the paper develops a“policy-technology-capital”analytical framework to explain the transition of regional clean energy cooperation from initial resource-industry complementarity toward deeper institution-market integration.Guided by this framework,the study proposes a roadmap and concrete policy recommendations for regional cooperation through 2030.These include:aligning regional emissions targets and renewable energy share goals;establishing a mutual recognition system for green standards;building a digitalized green supply chain and carbon traceability platform;designing cross-border green finance corridors;and constructing integrated electricity-hydrogen-storage corridors in synergy with the Belt and Road Initiative.The study concludes that,if effectively implemented,these measures could raise the regional share of renewable electricity generation to over 30%by 2030.China and ASEAN would then be well positioned to lead in forming a low-carbon,interconnected,and shared regional energy community,offering a replicable and scalable model for low-carbon transition across the Global South. 展开更多

This study investigates the critical intersection of cyberpsychology and cybersecurity policy development in small and medium-sized enterprises (SMEs). Through a mixed-methods approach incorporating surveys of 523 employees across 78 SMEs, qualitative interviews, and case studies, the research examines how psychological factors influence cybersecurity behaviors and policy effectiveness. Key findings reveal significant correlations between psychological factors and security outcomes, including the relationship between self-efficacy and policy compliance (r = 0.42, p β = 0.37, p < 0.001). The study identifies critical challenges in risk perception, policy complexity, and organizational culture affecting SME cybersecurity implementation. Results demonstrate that successful cybersecurity initiatives require the integration of psychological principles with technical solutions. The research provides a framework for developing human-centric security policies that address both behavioral and technical aspects of cybersecurity in resource-constrained environments. 展开更多
