The escalating global energy demand, coupled with the urgency of climate change, underscores the necessity for innovative approaches to achieve energy resilience and security. This study critically examines the interrelationship between global supply chain breadth, digital transformation, and energy resilience, addressing the key themes of this special issue across different aspects of energy security. This study used robust static panel data models for the assessment. Utilizing unbalanced data of 87 countries in 5 models and 95 countries in 6th model (2008–2022), the analysis results reveal a non-linear relationship between supply chain breadth and the five dimensions of energy security: availability, accessibility, affordability, acceptability, and developability while digitization had shown the moderating effect. The findings suggest that while the initial expansion of global supply chains may heighten vulnerabilities due to complexity and interdependence, long-term development fosters energy security through diversification and operational flexibility. Digital transformation is identified as a crucial moderator, stabilizing this dynamic by optimizing energy flow, reducing inefficiencies, and enabling an effective transition to renewable energy systems. Technologies such as blockchain and IoT enhance monitoring and management capabilities, mitigating disruptions and supporting sustainable energy governance. This study's findings provide actionable insights into how digitization strategies can be leveraged to align supply chain management with energy resilience objectives. By integrating supply chain theory with energy economics, this research offers a unique contribution to understanding the transformative potential of digital tools in mitigating energy risks while addressing broader sustainability goals. The policy implications emphasize the importance of digital infrastructure investment and cross-sector collaboration to design robust energy security strategies. This research study advances the discourse on supply chain digitization within the context of energy resilience, providing novel insights for policymakers, energy economists, and stakeholders aiming to navigate the challenges of a rapidly evolving energy landscape.

Extreme weather outcomes induced by climate change have been academically confirmed, but the substantial impact on residents is less paid attention to, especially from the aspects of energy expenses burden. Based on multi-annual survey data, we identify how the temperature changes affect Chinese household energy expenditure burden. After the fixed-effects panel model estimating, some unique findings are obtained: (1) The rising frequency of extreme temperatures significantly augment the electricity and energy expenditure burden for Chinese households. With the annual rise in the number of extreme temperature days, the demand for both heating and cooling among residents correspondingly escalates. (2) The impact of temperature extremes across different regions and socio-economic groups are heterogeneous, with rural, northern and low-income households experiencing higher influence of temperature extremes on energy expenses burden. (3) The influence of extreme temperatures is asymmetric. Extreme high temperatures have a stronger impact on energy burden compared to extreme low temperatures. The compounded effects of numerous extreme temperature days and heavy energy expenditure burden significantly magnify the impacts of weather on households. According to these conclusions, policy suggestions are proposed to mitigate household energy expenses burden.

This study investigates the evolving interplay between environmental governance and sustainability outcomes, employing dose-response analysis to underscore the necessity of accounting for these interdependencies in formulating climate and emissions policies. Our empirical evidence indicates that regulatory measures are pivotal in advancing sustainability within OECD countries, though their effects differ across various dimensions. Notably, stringent environmental regulations initially exacerbate energy security vulnerabilities in nations below a specific threshold; however, once policy intensity surpasses the threshold, they contribute substantially to mitigating such risks. A comparable pattern emerges for renewable energy adoption, where enhanced policy rigor fosters greater consumption. Paradoxically, tighter regulations induce a marginal uptick in CO₂ emissions. Moreover, insights from a dynamic panel threshold framework reveal that foreign direct investment (FDI) conditions the efficacy of environmental policies. As FDI rises, the beneficial influence of regulatory stringency on energy security and renewable utilization strengthens. Nevertheless, when FDI remains below 2.0, stringent environmental policies tend to elevate CO₂ emissions, whereas, beyond this threshold, the relationship reverses, leading to emission reductions. These findings underscore the intricate, non-linear interactions between environmental policy and sustainability, highlighting the imperative for calibrated policy frameworks that acknowledge threshold effects.

Evaluating Norway’s electric vehicle incentives

We use car registration data from 2000 to 2021, as well as price lists and tax rules, to evaluate Norway’s incentives for consumers to choose electric vehicles. These include taxes on fossil fuels, EV exemption from car purchase taxes, and other incentives, like discounts on road tolls. We find that undoing the incentive with the largest effect, the EV exemption from purchase taxes, would reduce the EV market share to 25 percent from the 66 percent observed in 2021, increase CO₂ emissions of new cars sold by 167 percent, reduce their total weight by 22 percent, and reduce the number of new cars sold by 10 percent. Lost tax revenues imply a carbon price of 1700 USD per metric tonne. But taking into account consumer and producer surplus, the tax exemption is welfare enhancing even before putting a value on emissions reductions.

我们利用2000年至2021年的汽车登记数据以及价目表和税收规则，对挪威鼓励消费者选择电动汽车的措施进行了评估。这些激励措施包括化石燃料税、电动汽车免征汽车购置税以及其他激励措施，如道路通行费折扣。我们发现，如果取消影响最大的激励措施--电动汽车免征购置税，电动汽车的市场份额将从 2021 年的 66% 降至 25%，售出新车的二氧化碳排放量将增加 167%，总重量将减少 22%，售出新车的数量将减少 10%。税收损失意味着碳价格为每公吨 1700 美元。但考虑到消费者和生产者盈余，即使在对减排量进行估值之前，免税也能提高福利。

This paper explores how heterogeneity across policymakers and the jurisdictions they represent, such as in their perceived external benefits from reducing greenhouse gas emissions, affects state and federal efforts to address climate change. State governments restrict their emissions anticipating spillback and the impact of their choice on trade flows. Federally, legislators restrict national emissions and distribute green pork to secure key votes. Heterogeneity gives rise to differential distortions across levels of the federation reflecting political failure. As a result, the central state policy undershoots mitigation relative to the conditionally Pareto optimal level using a central estimate of the global social cost of carbon whereas the central federal policy overshoots. Moreover, these policies achieve nearly the same amount of true surplus gains possible, 72.4% and 72.7%, respectively. State policies tend to be less regressive and provide true surplus gains to states that choose not to mitigate, whereas federal policy is likely to deliver losses to no voting districts. Taken together these results indicate that its possible for state policy to yield greater societal welfare than federal policy when policies generate transboundary spillovers and that there exists complex linkages between the relative political failure, emissions, efficiency, and equity impacts of policies selected across levels of the federation as a result of heterogeneity.

Energy regulations play a crucial role in enhancing firms' energy efficiency and environmental performance. However, their unintended effects, particularly on the adoption of industrial robots, have received limited attention. This paper leverages the implementation of China's Top 10,000 energy-consuming enterprises (TECE) program as an exogenous shock and employs a difference-in-differences methodology to assess the impact of energy regulations on industrial robot adoption and its potential underlying mechanisms. Additionally, the study examines the moderating role of human capital in shaping this relationship. To this end, we constructed firm-level variables for industrial robot usage and the intensity of energy regulation by integrating multiple micro-level datasets. Our findings indicate that energy regulations significantly reduce the usage of industrial robots. Specifically, the TECE project decreased the probability of regulated firms adopting industrial robots by 0.09 percentage points. Given that only 2.8 % of firms in the sample period used industrial robots, this impact is considerable. The deterioration of financial performance and increased R&D investment induced by energy regulations are likely channels for this effect. Furthermore, the energy regulation's negative impact is more pronounced for firms with higher levels of human capital. This is because such firms are more inclined to increase R&D investment, thereby crowding out investment in industrial robots.

We examine how Russian energy firms respond to international sanctions imposed by Western countries and their allies. The primary aim of these sanctions is to prevent Russia from accessing global trade markets. Using the sample of 13,319 Russian firms from 1994 to 2022, we find that sanctioned Russian energy firms hold significantly higher inventory levels compared to non-sanctioned firms. Sanctions have heterogeneous impacts across different firm characteristics. Large firms hold more inventory after being sanctioned, while highly leveraged firms significantly reduce their inventory levels. We also find that corporate inventory turnover is not significantly impacted, likely because sanctioned energy firms cannot promptly sell their products in response to the sanctions.

The rapid growth of the global new energy sector requires balancing supply chain diversification and centralization to manage policy uncertainty and market volatility. Using data from China's A-share listed new energy firms (2005–2022), this study finds that (1) upstream firms' perceptions of economic policy uncertainty significantly reduce downstream supply chain concentration, driving firms to adopt diversification strategies to mitigate risks; (2) mechanism analysis shows that risk tolerance and digital transformation amplify this effect, while cost control and innovation alleviate it; (3) further analysis reveals significant dynamic effects—firms initially diversify in response to short-term shocks but adjust strategies over time to balance efficiency and flexibility as uncertainty persists. Moreover, geopolitical risks intensify the diversification effects of policy uncertainty by increasing supply chain instability; (4) heterogeneity analysis highlights regional differences, ownership structures, and industry characteristics as key factors shaping supply chain adjustments. This research offers valuable guidance for resource-dependent industries to enhance resilience and support sustainable development amid global energy transitions.

This paper examines the causal effect of environmental information disclosure (EID) on regional carbon emissions through the lens of extensive and intensive margins of industrial development. We find that, on average, EID reduces regional carbon emissions by 5.4 % in treated cities relative to the control group following the launch of the Pollution Information Transparency Index (PITI). We then decompose regional carbon emissions into those of new industrial entrants (i.e., the extensive margin) and incumbent industrial firms (i.e., the intensive margin). We find that EID not only deters the entry of industrial firms but also inhibits the entry of manufacturing and carbon-intensive firms. At the intensive margin, we find that EID reduces corporate carbon emissions mainly through cutting industrial output rather than improving energy efficiency. Further analyses indicate that the mitigation effect on carbon emissions is much more prevalent in regions with stringent enforcement, strong legal environments, and high Internet penetration rates. This study highlights the importance of informal regulation in mitigating climate change.

Improving energy resilience, as a crucial strategy to resist the risk associated with energy systems in the context of increasing uncertainty, is a meaningful research direction whether it can be realized during the energy transition phase. This study empirically assesses the correlation between energy transition and energy resilience. It also explores their heterogeneity and the potential impact mechanisms using balanced panel data for 30 provinces in 17 years in China. The results are as follows: (i) Energy transition can enhance the resilience of the energy system; (ii) there is regional heterogeneity in this positive boosting effect, and the differences are due to the different types of renewable energy sources; (iii) green technology innovation and green finance are effective mediators between energy transition and energy resilience. Some effective and practical policy suggestions are proposed, and policymakers should uphold the principle of adapting to local conditions and a systematic regional differentiation policy.
