Strict regulations are usually regarded as valid tools for government to pursue sustainable development, while clear evidence is required to answer how the polluting firms actually respond to them, especially in the emerging markets with imperfect institution. With the data of 2848 Chinese A-share listed firms, this paper takes the enforcement of China's New Environmental Protection Law (NEPL) as an exogenous shock, and utilizes the difference-in-difference and tripe difference models to investigate how polluting firms strategically respond to strict environmental regulations. The results show that facing the pressure of NEPL, the polluting firms tend to pursue the community-related corporate social responsibility (CSR) as a strategic-political CSR, rather than fulfill environmental responsibility obediently. Significantly, the strategy obviously varies for firms with different bargaining power with local governments and mainly works for the state-owned firms, large taxpayer or large employer, while the non-state-owned or small firms would still pursue environmental compliance as required. Though does crowd out the environmental performance, more strategic-political CSR engagement, instead, shelter firms from environmental penalty while benefiting other stakeholders. This paper helps understand the motivations and outcomes of regulated firms' strategic response to strict environmental regulations, which is particularly relevant to not only China, but also other emerging markets with similar government intervention and passive CSR fulfillment.

严格的监管通常被视为政府追求可持续发展的有效工具，但污染企业如何应对这些监管需要明确的证据，特别是在制度不完善的新兴市场。本文以2848家中国a股上市公司的数据为样本，将中国新环境保护法的实施作为外生冲击，运用差中差模型和三分差模型考察污染企业如何对严格的环境法规做出战略反应。结果表明，面对新能源政策的压力，污染企业倾向于将社区企业社会责任作为一种战略-政治企业社会责任来追求，而不是顺从地履行环境责任。值得注意的是，与地方政府议价能力不同的企业，其策略明显不同，主要适用于国有企业、大纳税人或大雇主，而非国有或小型企业仍会按要求追求环境合规。虽然会排挤环境绩效，但更具战略政治性的企业社会责任参与反而使企业免受环境惩罚，同时使其他利益相关者受益。本文有助于理解受监管企业对严格环境法规的战略反应的动机和结果，这不仅与中国特别相关，而且与其他具有类似政府干预和被动履行企业社会责任的新兴市场也特别相关。

This study investigates the causal impact of regional climate policy on corporate cross-regional investment location choices in China. Exploiting the quasi-experimental shock of the Low-Carbon City Pilot program through a staggered difference-in-differences method, we find that the policy implementation significantly reduces the Mergers and Acquisitions activities targeting firms in regulated cities. In addition, firms within regulated regions exhibit a higher propensity to establish subsidiaries in non-regulated regions, reflecting strategic relocation to mitigate regulatory risks. One potential explanation is that the climate policy introduces region-specific uncertainty, amplifying investors' and managers' risk perceptions regarding climate transition exposure in regulated areas. Heterogeneity analysis reveals that the effects are more pronounced in firms with lower information disclosure quality, entrenched management, financial constraints, and firms under non-high-tech industries. Our findings highlight unintended consequences of climate policy, and provide timely policy implications for central regulators in developing economies to balance environmental objectives with firms' adaptive investment behaviors when designing place-based climate policies.

本研究探讨了区域气候政策对中国企业跨区域投资区位选择的因果影响。利用低碳城市试点项目的准实验冲击，通过交错差中差方法，我们发现政策的实施显著减少了针对受监管城市企业的并购活动。此外，受监管地区内的公司更倾向于在非监管地区建立子公司，这反映了为减轻监管风险而进行的战略转移。一种可能的解释是，气候政策引入了特定地区的不确定性，放大了投资者和管理者对受监管地区气候转型风险敞口的风险感知。异质性分析表明，在信息披露质量较低、管理根深蒂固、财务约束条件较差的企业和非高新技术产业中，这种影响更为明显。我们的研究结果突出了气候政策的意外后果，并为发展中经济体的中央监管机构在设计基于地方的气候政策时平衡环境目标与企业适应性投资行为提供了及时的政策启示。

Four in five people without access to electricity live in Sub-Saharan Africa, where mini-grids are seen as a key solution. Yet investment remains constrained by low and unpredictable demand, especially in fragile settings. We study electricity demand in North Kivu (Democratic Republic of Congo), using pre-grid census and survey data combined with six years of post-connection consumption records. Five key findings emerge: (i) demand is highly heterogeneous across and within localities, with pockets of low uptake; (ii) pre-grid covariates explain some variation but have limited predictive power for realized connection and consumption; (iii) SMEs consume far more per connection than households while making up a small share of connections; (iv) consumption rises after connection and then plateaus, indicating slow movement up the energy ladder; (v) conflict shocks temporarily depress consumption, but usage rebounds, highlighting resilience in the face of insecurity. We further examine how an integrated, demand-building strategy by the local operator can partially mitigate these challenges. The case highlights that mini-grid viability in fragile settings may depend less on improved demand forecasting and more on the capacity to build and coordinate demand alongside infrastructure, with implications for policy design, risk-sharing finance, and the role of public and donor support.

五分之四用不上电的人生活在撒哈拉以南非洲，在那里微型电网被视为一个关键的解决方案。然而，投资仍然受到需求低迷和不可预测的制约，特别是在脆弱的环境中。我们研究了北基伍省（刚果民主共和国）的电力需求，使用了电网前的人口普查和调查数据，并结合了六年的并网后消费记录。出现了五个主要发现：(i)地方之间和地方内部的需求高度异质，有一些地方的吸收率很低；（ii）电网前协变量解释了一些变化，但对实现连接和消耗的预测能力有限；（三）中小企业的单次连接消费远高于家庭，但所占的连接比例却很小；（iv）连接后消耗上升，然后趋于平稳，表明能源阶梯向上移动缓慢；（五）冲突冲击暂时抑制消费，但消费回升，凸显面对不安全的韧性。我们进一步研究了当地运营商的综合需求建设战略如何在一定程度上缓解这些挑战。该案例强调，在脆弱环境中，微型电网的可行性可能更少地依赖于改进的需求预测，而更多地依赖于在基础设施建设的同时建设和协调需求的能力，这对政策设计、风险分担融资以及公共和捐助者支持的作用都有影响。

Internal governance is the process through which subordinate executives, driven by their longer decision horizons and focus on long-term value, counteract the CEO's short-term self-interests to influence corporate decisions. We examine whether and how internal governance affects eco-innovation, which delivers long-term value at the expense of initial investment outlays. We find that more effective internal governance motivates eco-innovation and that this effect operates through two channels. First, subordinate executives' bottom-up influence on the CEO prompts them to increase their long-term awareness to exercise this influence and motivate eco-innovation. Second, more effective internal governance enhances the top management team's ecological awareness to motivate eco-innovation. We further reveal that subordinate-driven internal governance plays a more significant role when CEOs are more opportunistic. Last, we find that more effective internal governance improves eco-innovation quality, highlighting that subordinates play an important role in both the quantity and quality of firms' eco-innovation.

内部治理是下属高管在更长远的决策视野和对长期价值的关注的驱使下，抵消CEO的短期自身利益，从而影响公司决策的过程。我们研究内部治理是否以及如何影响生态创新，生态创新以初始投资支出为代价提供长期价值。我们发现，更有效的内部治理可以激励生态创新，这种效应通过两个渠道发挥作用。首先，下级高管对CEO自下而上的影响力促使他们增强行使这种影响力的长期意识，从而推动生态创新。第二，更有效的内部治理可以增强高层管理团队的生态意识，从而激发生态创新。我们进一步发现，ceo机会主义倾向越强，下属驱动型内部治理的作用越显著。最后，我们发现更有效的内部治理可以提高生态创新的质量，强调下属对企业生态创新的数量和质量都起着重要作用。

While the transport sector accounts for around 25% of the EU's total GHG emissions, the adoption of electric vehicles (EVs) plays an important role in achieving the EU's net zero emissions goal. Alongside subsidies or tax exemptions for EV purchases, energy prices, i.e., electricity price and gasoline price, can also serve as policy instruments to encourage consumers to shift from internal combustion engine (ICE) vehicles to EVs. Using a unique panel of EV registrations at the product-level from four Nordic countries (Denmark, Finland, Norway, and Sweden), this paper investigates how electricity prices and gasoline prices stimulate the adoption of EVs. The results show that gasoline prices have a more statistically significant effect on the adoption of EVs (as a substitute for ICE vehicles), compared with electricity prices. On average, 1% increase in gasoline price would increase the sales of EVs by 0.85% and the effect is larger for EV models with relatively lower purchase cost (where the effect of electricity price is also found statistically significant) and those with less-known brands. Further simulation results show that a 1% increase in the gasoline price would reduce the lifecycle GHG emissions of new automobiles by 0.16%. Our study highlights the importance of energy prices in accelerating EV adoption and mitigating carbon emissions in the Nordic countries.

虽然交通运输部门占欧盟温室气体排放总量的25%左右，但电动汽车（ev）的采用在实现欧盟净零排放目标方面发挥着重要作用。除了购买电动汽车的补贴或免税外，能源价格，即电价和汽油价格也可以作为鼓励消费者从内燃机汽车转向电动汽车的政策工具。本文利用来自四个北欧国家（丹麦、芬兰、挪威和瑞典）的独特的电动汽车产品注册面板，研究了电价和汽油价格如何刺激电动汽车的采用。结果表明，与电价相比，汽油价格对采用电动汽车（作为内燃机汽车的替代品）的影响在统计上更为显著。平均而言，汽油价格上涨1%会使电动汽车销量增加0.85%，对于购买成本相对较低的电动汽车车型（电价的影响也有统计学意义）和品牌知名度较低的电动汽车车型的影响更大。进一步的模拟结果表明，汽油价格每上涨1%，新车生命周期温室气体排放量将减少0.16%。我们的研究强调了能源价格在加速电动汽车普及和减少北欧国家碳排放方面的重要性。

Access to electricity remains a central priority in development policy, particularly in Sub-Saharan Africa (SSA), which accounts for over half of the global population without reliable power. This study examines the socio-economic impacts of Kenya’s Last Mile Connectivity Project (LMCP), a large-scale electrification initiative aimed at expanding grid access by connecting households and businesses within 600 meters of distribution transformers. Using a spatial regression discontinuity design, we evaluate the program’s effectiveness in increasing electricity access and its broader development outcomes. Our findings show that the LMCP significantly improved household connectivity, leading to a substantial shift from off-grid energy sources to grid electricity. While this transition resulted in modest yet positive economic effects, most notably, increased household consumption, there was no significant impact on employment, income, or women’s empowerment. These limited economic gains appear to stem from persistent challenges such as unreliable power supply and financial constraints that hinder productive electricity use. Interestingly, we find that the positive impact of LMCP on consumption is driven by households connected earlier, suggesting that the impact of the program might increase over time. While our results highlight the role of electrification in improving living conditions, they also suggest that access alone may not be sufficient to drive broader economic transformation, and benefits take time to accrue.

获得电力仍然是发展政策的核心优先事项，特别是在撒哈拉以南非洲（SSA），该地区占全球没有可靠电力的人口的一半以上。本研究考察了肯尼亚“最后一英里连接项目”（LMCP）的社会经济影响，这是一项大型电气化倡议，旨在通过连接配电变压器600米范围内的家庭和企业来扩大电网接入。利用空间回归不连续设计，我们评估了该项目在增加电力供应方面的有效性及其更广泛的发展成果。我们的研究结果表明，LMCP显著改善了家庭连通性，导致从离网能源到电网电力的实质性转变。虽然这一转变带来了适度但积极的经济影响，最显著的是增加了家庭消费，但对就业、收入或妇女赋权没有显著影响。这些有限的经济收益似乎源于持续存在的挑战，如不可靠的电力供应和阻碍生产性电力使用的财政限制。有趣的是，我们发现LMCP对消费的积极影响是由早期连接的家庭推动的，这表明该计划的影响可能会随着时间的推移而增加。虽然我们的研究结果强调了电气化在改善生活条件方面的作用，但它们也表明，仅靠电气化可能不足以推动更广泛的经济转型，而且效益需要时间来积累。

Despite the increasing number of net-zero commitments worldwide, a significant gap remains between climate targets and their real-world implementation effects. This study conducts a systematic meta-analysis of 99 empirical studies, integrating more than 1000 standardized effect sizes across 37 decarbonization policy instruments worldwide. The results show that the distribution of samples across regions is highly uneven, with studies from the European Union (EU), the United States (US), Canada, and China accounting for most of the evidence base. We observe that market-based instruments, particularly carbon pricing and taxation measures, as well as several emissions trading systems (ETS) (e.g., the UK's carbon price support, Canada's ETS, the US cap-and-trade, and China's ETS), exhibit statistically significant emission reduction effects. Through multi-model comparisons, our analysis reveals that the average abatement effect of policies ranges between national emissions reductions of 10.5% and 12.6%. However, policies such as net energy metering, emissions performance standards, and the Swiss ETS show counterproductive mitigation effects, e.g. increases in emissions. Our interaction analysis shows that policy effectiveness depends highly on how well a given instrument aligns with sectoral characteristics. Energy efficiency policies perform well when applied within a single sector but perform very differently when used across sectors. Market-based mechanisms also display clear sectoral selectivity in their performance. This study not only reveals the variation in mitigation outcomes across policy instruments and sectors but also provides empirical evidence on how institutional conditions shape policy performance. The findings offer practical insights for building more effective, inclusive, and sustainable pathways toward decarbonization.

尽管全球净零排放承诺的数量不断增加，但气候目标与其实际实施效果之间仍存在巨大差距。本研究对99项实证研究进行了系统的荟萃分析，整合了全球37种脱碳政策工具的1000多个标准化效应量。结果表明，样本在不同地区的分布极不均匀，来自欧盟（EU）、美国（US）、加拿大和中国的研究占了大部分证据基础。我们观察到，以市场为基础的工具，特别是碳定价和税收措施，以及一些排放交易体系（ETS）（如英国的碳价支持、加拿大的ETS、美国的限额与交易和中国的ETS），在统计上显示出显著的减排效果。通过多模型比较，我们的分析表明，政策的平均减排效果在国家减排10.5%至12.6%之间。然而，净能源计量、排放绩效标准和瑞士排放交易体系等政策显示出适得其反的缓解效果，例如排放量增加。我们的相互作用分析表明，政策有效性在很大程度上取决于给定工具与部门特征的契合程度。能源效率政策在单一部门内应用效果良好，但在跨部门使用时效果大不相同。市场机制的表现也显示出明显的部门选择性。这项研究不仅揭示了不同政策工具和部门之间缓解结果的差异，而且还提供了关于制度条件如何影响政策绩效的经验证据。研究结果为构建更有效、包容和可持续的脱碳途径提供了实际见解。

In emerging markets characterized by heavy government intervention, government-dominated resource allocation plays an important role in cultivating sustainable firms. This paper investigates its effectiveness in fostering corporate green innovation by exploiting a quasi-experimental setting in China. We find that the government-led resource allocation reform known as the Area-based Evaluation Mechanism Reform detrimentally influences green innovation activities of highly polluting firms. We attribute the negative effect to the short-termism channel rather than the quiet life channel, as the reform drives firms toward short-termism, crowding out their incentives for long-term environmental sustainability. We also investigate how this reform interacts with local government incentives. Although the reform delivers short-term economic gains, these benefits do not justify the observed reductions in corporate green innovation, productivity, and innovative efficiency. Our empirical evidence highlights the unintended negative consequences of the policy instrument for sustainable development and the need to place greater focus on environmental targets in emerging markets.

在政府干预严重的新兴市场中，政府主导的资源配置对可持续企业的培育起着重要作用。本文利用中国的准实验环境来考察其在促进企业绿色创新方面的有效性。研究发现，政府主导的资源配置改革，即区域评价机制改革，对高污染企业的绿色创新活动产生了不利影响。我们将这种负面影响归因于短期主义渠道，而不是平静生活渠道，因为改革推动企业走向短期主义，挤出了它们对长期环境可持续性的激励。我们还研究了这一改革如何与地方政府的激励措施相互作用。尽管改革带来了短期的经济收益，但这些收益并不能证明观察到的企业绿色创新、生产力和创新效率的下降是合理的。我们的经验证据强调了可持续发展政策工具的意外负面影响，以及对新兴市场环境目标给予更多关注的必要性。

As Europe phases out petroleum-powered vehicles, plug-in electric vehicles (PEVs) are expected to become the norm. However, realizing their full environmental and grid-stabilizing potential depends on drivers' willingness to adopt home chargers that support flexibility services, such as shifting charging to off-peak hours, responding to variable renewable energy supply, and selling stored electricity back to the grid. Using a discrete choice experiment with a sample of 769 Belgian drivers (representative by age, region, and gender), we structurally estimate an implicit discount rate (IDR) that captures drivers' willingness to trade upfront charger costs for future annualized electric-bill savings. This model simultaneously estimates preferences for specific flexibility-enhancing features, revealing which types of charging flexibility drivers are most willing to adopt. We find that the average driver applies an IDR of 28.5%, while a latent majority class comprising 79.86% of respondents—younger, better-educated drivers—applies a lower IDR of 23%. Since both of these IDRs are greater than the typical 4–5% financial market interest rate, we conclude that drivers apply a flexibility discount rate gap to PEV charging investment. Nonetheless, they also show a willingness to adopt solar charging, dynamic load management, and vehicle-to-home-and-grid charging, indicating potential for the majority of drivers to adopt flexible PEV chargers once financial barriers are addressed. Finally, our results show behavioral, demographic, and attitudinal characteristics that are associated with membership in the majority class—those more likely to invest in a flexible charger—highlighting pathways to bridge the discount rate gap and promote adoption of flexibility-enabling technologies.

随着欧洲逐步淘汰石油动力汽车，插电式电动汽车（pev）有望成为常态。然而，能否充分发挥其环保和电网稳定的潜力，取决于车主是否愿意采用支持灵活服务的家庭充电器，比如将充电转移到非高峰时段，响应可变的可再生能源供应，以及将储存的电力卖回电网。通过对769名比利时司机（按年龄、地区和性别具有代表性）的离散选择实验，我们从结构上估计了隐含贴现率（IDR），该贴现率反映了司机愿意用预付充电器成本来节省未来年度电费的意愿。该模型同时估计了对特定灵活性增强功能的偏好，揭示了哪种类型的充电灵活性驱动程序最愿意采用。我们发现，司机平均使用的印尼卢比比率为28.5%，而潜在的多数阶层，包括79.86%的受访者——年轻、受过良好教育的司机——使用的印尼卢比比率较低，为23%。由于这两个idr都大于典型的4-5%的金融市场利率，我们得出结论，司机对PEV充电投资采用弹性贴现率差距。尽管如此，他们也表示愿意采用太阳能充电、动态负载管理以及车辆到家庭和电网充电，这表明一旦解决了财务障碍，大多数司机都有可能采用灵活的电动汽车充电器。最后，我们的研究结果显示了与大多数阶层成员相关的行为、人口统计和态度特征——这些特征更有可能投资于灵活的充电器——突出了弥合折扣率差距和促进灵活技术采用的途径。

Energy poverty, a complex multidimensional challenge, is a key obstacle to achieving sustainable development. This study provides the first nationwide causal assessment of China's Photovoltaic Poverty Alleviation (PVPA) policy on multidimensional energy poverty (MEP) using a balanced panel of 1928 counties from 2013 to 2020, covering approximately 90% of the nation's poor population. We assess the dynamic impacts of PVPA on MEP, measured through the multidimensional energy poverty index (MEPI), which captures dimensions such as cooking, lighting, and communication—by applying staggered difference-in-differences (DID), Callaway and Sant'Anna's heterogeneity-robust DID (CSDID), Honest-DID, and spatial DID methods. Results show that PVPA significantly alleviates MEP through two reinforcing pathways: first by increasing household income via PV electricity revenue and rural employment, and second by enabling clean energy substitution, reducing reliance on biomass and coal. Between 2013 and 2020, China's national MEPI declined by 23%, with stronger PVPA effects observed in low-coal, low-vegetation, and relocation-targeted areas, while regions with entrenched traditional energy use showed weak effects. Mechanism analysis confirms that both income enhancement and service improvement contribute to these gains. This study provides robust causal evidence linking renewable energy–driven poverty alleviation to MEP reduction, offering policy insights on embedding energy access targets in rural revitalization, tailoring interventions to regional contexts, and sustaining improvements through distributed energy storage and infrastructure upgrades.

能源贫困是一项复杂的多方面挑战，是实现可持续发展的主要障碍。本研究首次在全国范围内对光伏扶贫（PVPA）政策对多维能源贫困（MEP）的影响进行了因果评估，采用了一个平衡面板，从2013年到2020年，覆盖了约90%的全国贫困人口。我们通过多维能源贫困指数（MEPI）评估了PVPA对MEP的动态影响，该指数通过交错差中差（DID）、Callaway和Sant’anna的异质性稳健DID （CSDID）、Honest-DID和空间DID方法，捕捉了烹饪、照明和通信等维度。结果表明，PVPA通过两种强化途径显著缓解MEP：一是通过光伏发电收入和农村就业增加家庭收入，二是通过实现清洁能源替代，减少对生物质和煤炭的依赖。2013 - 2020年，中国全国MEPI下降了23%，其中低煤、低植被和搬迁目标地区的PVPA效应较强，而传统能源利用地区的影响较弱。机制分析证实，增加收入和改善服务都有助于这些收益。本研究提供了强有力的因果证据，将可再生能源驱动的扶贫与减少环境环境保护联系起来，为在乡村振兴中嵌入能源获取目标、根据地区情况量身定制干预措施以及通过分布式储能和基础设施升级持续改善提供政策见解。
