Due to the social value and economic significance of food waste recovery system, an examination is conducted on a sustainable food waste supply chain (SFWSC) with government environmental oversight. Under the uncertain amount of food waste collected daily, a novel globalized robust bi-level programming model with government oversight is proposed to optimize the reuse of food waste to minimize total costs and negative environmental impacts such as CO<sub>2</sub> and CH<sub>4</sub>. The characterization of the uncertainty of food waste involves a pair of inner and outer uncertainty sets. Based on strong duality theory, the globalized robust bi-level optimization model can be transformed into a computationally tractable mixed integer programming model. To improve solution efficiency and quality, this paper employs the Benders decomposition (BD) algorithm with two accelerated strategies to solve the equivalent model. Lastly, a large-scale case study of food waste management in Shandong Province, China, is carried out to showcase the applicability of the proposed model and algorithm. The results indicate that food waste companies can reduce total costs without increasing environmental impacts under government environmental oversight.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"99 ","pages":"Article 102205"},"PeriodicalIF":6.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724476","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}

Since 2003, China has revamped its rural road construction policy, transitioning from “workers self-organised construction (Min Gong Jian Qin)\" to a “one project, one discussion (Yi Shi Yi Yi)\" approach and significantly increasing government investment. This study evaluates the impact of various financing sources—externally funded, self-financed, and mix financed—on rural off-farm income and migration intentions using the Chinese Household Income Project survey data, employing difference-in-differences and propensity score matching methodologies to analyze the socio-economic impacts of rural road projects financed through different sources on off-farm work income and migration intentions of the rural Chinese population. Findings reveal that externally funded road projects significantly enhance off-farm income and encourage migration intentions for work. Conversely, self-financed projects that rely on local villagers' contributions and voluntary labor, show no positive impact on off-farm income and unexpectedly reduce migration intentions. Importantly, projects with mixed financing models were found to have no significant impact on either off-farm income or migration patterns, highlighting challenges in the coordination and efficacy of these hybrid financing strategies. These results contribute to the discourse on public sector decision-making by demonstrating the critical role of government-funded infrastructure in facilitating socio-economic development in rural areas. The study underscores the importance of strategic resource allocation and effective financing models in enhancing rural infrastructure, increasing income, and enabling rural out-migration for improved livelihoods.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"99 ","pages":"Article 102209"},"PeriodicalIF":6.2,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead of expected utility maximization, we assume that an e-commerce platform and a green manufacturer seek to maximize profits under uncertain demand based on greenness and delivery time difference with a certain confidence level, from which two centralized models and four Stackelberg decentralized models are constructed.The results show that supply chain members’ choice of sales mode is associated with risk attitude.In addition, the impact of promised delivery time on the optimal profitability of the supply chain member who is responsible for product delivery is related to the strength of consumer incentives under the reward and penalty mechanism. More importantly, the introduction of the consumer reward and penalty mechanism can effectively improve the greenness of products, the efficiency of delivery, the optimal profits of supply chain members and social welfare.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"99 ","pages":"Article 102203"},"PeriodicalIF":6.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687626","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}

The problem involves determining which sites to visit, in what sequence, and how much time to spend at each site to collect information within a total assessment time limit. We present a mathematical model that balances site coverage and sampling accuracy, and propose a constructive heuristic and a tabu search algorithm to efficiently solve large-scale instances. Computational experiments demonstrate that the tabu search algorithm can quickly obtain optimal or near-optimal solutions for large instances, while the performance of the heuristic is influenced by network topology. We illustrate the effectiveness of our approach through a case study based on the 2011 Van Earthquake in Turkey.

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}
