Two modes of ETS implementation are commonly applied across supply chains: separately imposed ETS (S-ETS) and jointly imposed ETS (J-ETS). However, it is unclear how the two distinct modes of ETS implementation influence the economic and environmental performance of supply chains. This paper considers a low-carbon supply chain system comprising one supplier and one manufacturer, where all carbon emissions generated by supply chain members are constrained by ETS. By employing game theory and MATLAB numerical analysis software, this study investigates the impacts of the two ETS modalities on carbon abatement decisions, profitability and social welfare within the supply chain. Furthermore, the study examines a scenario incorporating government subsidies to enhance ETS efficiency. The results show that compared to S-ETS, J-ETS can reduce total carbon emissions of the supply chain with high carbon emission intensity. From the perspective of social welfare, J-ETS is also more advantageous for such supply chains. However, this ETS modality may negatively impact the supplier's profitability. When government subsidies are introduced into J-ETS, coordinated improvements in the economic and environmental performance of the supply chain can be achieved. This paper also provides the government with subsidy level conditions under which J-ETS can maximize social welfare for supply chains with varying carbon emission intensities.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"99 ","pages":"Article 102202"},"PeriodicalIF":6.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681252","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}

However, the station might introduce toxic additives to enhance product appearance and stimulate demand. The manufacturer further processes the milk and sells it to consumers. In an endeavor to curb both toxic and non-toxic adulterations, the government employs regulatory measures and subsidy schemes. The impact of government regulations on the various segments of the supply chain is analyzed using game theory in this study. Additionally, the study explores the influence of diverse contractual arrangements on decision variables and player profit functions. To this end, four scenarios are analyzed: decentralized structure, cost-sharing contract, safety guarantee contract, and hybrid contract. The findings reveal that intensifying deterrent factors not only enhances product safety but also leads to a reduction in non-toxic adulterations. It is observed that the cost-sharing contract can augment the profitability of all supply chain members. Furthermore, the study concludes that the allocation of inappropriate subsidy levels can induce increased additive usage by members, which contradicts the government's objectives in providing subsidies.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"99 ","pages":"Article 102200"},"PeriodicalIF":6.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643458","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}

While high-speed rail (HSR) networks have played an increasingly significant role in regional economic development, their impact on public health—especially mental health—remains underexplored. The present paper is the first study targeting on mental health of the expansion of HSR network among the particular group, i.e., the middled-aged and elderly adults who are with accumulative wealth and losing health. Leveraging Staggered Difference-in-Differences (DID) and high-dimensional fixed effects (HDFE), this study investigates the cumulative effects of HSR development on individuals’ mental health using micro-panel data from the China Health and Retirement Longitudinal Study (CHARLS) for the years 2011, 2013, 2015, and 2018. After addressing endogenous issues, our findings suggest that both the introduction and further operation of HSR services positively influence the mental health of this demographic group. These results hold up under a series of robustness checks. Furthermore, the mechanisms behind this improvement include increased mobility for social visits, enhanced regional green technology innovation, and reduced pollution levels. The positive impact is particularly pronounced among individuals who are not yet retired and remains consistent across various residential and domicile settings.

The results show that highway improvements in underdeveloped regions exert a siphoning, rather than diffusion, effect on firm location in the short and long term. This effect, however, dissipates under four scenarios: higher resource endowment, larger market size, greater spatial distance from large cities, or smaller economic disparity with large cities. This indicates that firm location is also influenced by the interplay of “agglomeration” and “dispersion” in developed regions, and “exclusion” and “attraction” in underdeveloped regions after highway improvements. Additionally, the impacts of different highway classes vary, with inter-regional highways mainly leading to the siphoning effect, and intra-regional highways exerting a diffusion effect under the abovementioned scenarios.
