The results indicate that achieving a desirable equilibrium of effective protection, active innovation, and accelerated transition relies on the coordinated implementation of three policy instruments: IP protection, innovation subsidies, and environmental regulation. The absence or misalignment of any policy tool may lead the system to an undesirable equilibrium marked by transition stagnation. An optimal threshold for IP enforcement intensity is identified. This threshold is negatively correlated with enforcement costs at the institutional level but positively correlated with the economic benefits and life cycle of green technologies at the technological level. The follower firm exhibits the slowest innovation response, and its sustained innovation depends on a compensatory policy mix that combines IP enforcement with innovation subsidies. While higher prices for green technologies incentivize R&amp;D, they also hinder diffusion. This study fills a theoretical gap in the literature concerning the multi-agent interaction mechanisms guiding energy transition through innovation institutions and provides a theoretical foundation for constructing a green-oriented IP policy system.</div></div>","PeriodicalId":11665,"journal":{"name":"Energy Economics","volume":"151 ","pages":"Article 108901"},"PeriodicalIF":14.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As countries seek innovative solutions to expand energy access, artificial intelligence (AI) has emerged as a promising tool. While recent studies have explored the role of AI in improving energy access, few have considered its spatial effects. Therefore, this paper investigates how AI adoption affects energy poverty using a spatial panel dataset of 64 countries from 2010 to 2019. Spatial econometric models reveal that higher AI adoption is significantly associated with reductions in energy poverty and that these benefits extend beyond national borders through regional spillovers. Mediation analysis shows that technological innovation, proxied by patent activity, partially transmits the impact of AI, while moderation analysis reveals that the effect of AI is stronger in less urbanized settings and where public spending is relatively low. These findings provide the first empirical evidence of spatial dependence in the AI–energy poverty nexus and highlight the importance of designing targeted, regionally coordinated policies. Thus, promoting AI-enabled off-grid solutions and strengthening innovation systems could help reduce spatial disparities in energy access, especially when embedded within broader international partnerships and adaptive national energy policies.</div></div>","PeriodicalId":11665,"journal":{"name":"Energy Economics","volume":"151 ","pages":"Article 108909"},"PeriodicalIF":14.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our analysis is also extended to use another proxy of energy security for 36 countries in an extended and updated period from 2013 to 2022. Our results show that green finance can significantly reduce energy security risks worldwide. Furthermore, our heterogeneity analysis shows that the impact of green finance on energy security risks is also more substantial in the OECD (IEA) countries than in non-OECD (non-IEA) countries. Results from the panel quantile regression also show that the impact of green finance is heterogeneous and significant across different quantiles of energy security. This finding suggests a V-shaped pattern from the effect of green finance, indicating that countries with either very high or very low levels of energy security risk benefit the most from green finance. Interestingly, when green finance is considered a moderator in the effect of geopolitical risk on energy security, we find that green finance acts as a shield against the adverse impacts of increasing geopolitical risk.

The model incorporates three innovative elements: the disutility of carbon emissions on social welfare, explicit differentiation of transmission pathways between brown and green firms, and reconceptualized firm-level ESG incentives. Simulation analyses of four distinct shocks—household green investment preference, brown firm collateral ratio, emission reduction effort, and emission tax—reveal several key dynamics. Notably, while increased household green investment preference leads to a short-term decline in brown firms’ brown investment, such investment gradually recovers in the long term, and emission stocks still see a reduction. Although heightened market expectations regarding brown firms’ ESG performance can boost their output, they may weaken their motivation to reduce emissions and exacerbate pollution. Meanwhile, while enhanced emission reduction efforts improve the environment in the short term, they exert a sustained dampening effect on investment in green firms. Furthermore, emission tax increases yield long-term benefits for green firms and the environment, despite exerting persistent negative impacts on brown firms.

We get several important insights from this study. First, a positive correlation exists between the transmission capacity and interregional power dispatch. Enhanced transmission line expansion increases interregional power transactions by approximately 90 %. Second, grid extension enables a broader power supply source. It has a prominent role in maintaining the power supply and enhancing renewable power absorption, especially in the case of power shortages. Third, the grid extension and interregional power transactions narrow the price gap among provinces.
