The proposed method, Variable RTS in Hierarchical Network DEA (VRS-HNDEA), addresses these limitations by integrating variable RTS, enabling a detailed efficiency analysis across hierarchical systems with heterogeneous sub-units. By utilising free variables, this model establishes distinct efficiency planes for simultaneous benchmarking of diverse subsystems, yielding a global efficiency frontier through the Minkowski addition of sub-system sets and analysed using an input-oriented enveloped form. Applied specifically to the higher education sector, the VRS-HNDEA model provides insights into the operational efficiency of various academic functions, including teaching, research, and administration. Key findings from this application demonstrate the model's ability to capture efficiency variations across hierarchical levels, supporting nuanced decisions on resource allocation and scale optimization.

After the decomposition of the labor income share, it is found that the increase in the labor income share due to the increase in the level of social insurance contributions is attributable to the increase in per capita labor compensation exceeding the increase in labor productivity. After the implementation of the Law, the labor income share increased more for firms that were subject to stricter tax control, stronger labor protection, more difficult cost shifting, smaller elasticity of factor substitution, and weaker degree of financing constraints. This study better explains the phenomenon of China's labor income share rebound, provides empirical evidence from developing countries to increase the labor income share, and emphasizes the importance of protecting workers' social insurance rights and interests and regulating firms' social insurance contribution behavior to increase the labor income share, which helps to deepen the understanding of the role of social insurance system reform in regulating income distribution.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"97 ","pages":"Article 102103"},"PeriodicalIF":6.2,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747250","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}

Additionally, interdependent networks may have multiple functions, system users, owners, and stakeholders. There is a need for data-informed decision-making models that address resilience and risk for these interdependent infrastructure networks. We address these issues by: 1) Modeling interdependencies among infrastructure networks using a multi-layer interdependent network framework, 2) Quantifying the relationship between network resilience and the inter-network connection structure, and 3) Supporting management and strategic decision-making for investment in inter-network connection structures, supporting risk mitigation needs and strategies. Our paper combines network optimization and network science methods to produce a unified framework to analyze resilience.

Our study bridges this gap by employing a game-theoretic model that incorporates monopoly and duopoly markets to explore these effects. Our findings indicate that family members' perception bias for ECIs' services negatively impacts ECIs' prices, demand, and profit. Moreover, we find that in the monopoly market, an ECI should adopt the outsourcing strategy to reduce losses if family members' perception bias is higher. In the duopoly market, when family members' perception bias is higher, if one ECI adopts the outsourcing strategy, then the other ECI should opt for the self-providing strategy, and vice versa. Furthermore, we observe that a higher perception bias decreases family surplus and social welfare in the monopoly market. However, it may sometimes benefit family surplus and social welfare in the duopoly market. Our results offer insightful takeaways for ECIs' operational strategies and policymakers’ welfare policies in the elder care service market.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"98 ","pages":"Article 102107"},"PeriodicalIF":6.2,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143134550","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, due to the variability in cargo properties and the influence of various factors on transportation route decisions, formulating a low-carbon and economical multimodal freight transport plan remains a significant challenge. To address the issue, this study considered cargoes with different attributes in terms of both value and time attributes. Triangular fuzzy numbers were employed to represent the uncertain demand for cargo, with confidence levels introduced for clarification. A low-carbon route decision optimization model for multimodal freight transport was established to minimize the combined transportation carbon emission and time costs. The catastrophe adaptive genetic algorithm, based on Monte Carlo sampling, was employed to solve the model using arithmetic examples. Finally, parameter sensitivity analysis revealed that adjustments to carbon tax values and changes in the proportion of electric trucks and green electricity supply had the most significant impact on the low-carbon route decision-making plan for multimodal freight transport. For low value-added and timeliness-strong cargo, a 60 % increase in carbon tax value shifted the mode of transportation from road to railway. When the carbon tax increased by more than 140 %, the transportation mode shifted from railway to waterway. Additionally, when the proportion of electric trucks and green electricity supply both exceeded 80 %, the transportation mode between some city nodes shifted from railway to road. When these proportions increased beyond 90 %, road transportation became the predominant mode.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"96 ","pages":"Article 102108"},"PeriodicalIF":6.2,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651419","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}
