“…The chain‐wide effects on water, nitrogen, phosphorus, and biomass (HANPP) consumption exhibit a significant degree of heterogeneity due to regional differences in dietary composition. In order to determine the effects of the various sectors (Cheng et al., 2024; Meng et al., 2021; Ogunmoroti et al., 2022) and create suitable policy suggestions (Cheng et al., 2023; Tahir et al., 2022), this calls for the construction of more accurate input‐output tables. Therefore, further consideration will also be given to this in the future, as data allows.…”

As human consumption expands, four environmental footprints (EFs) exceed the planetary boundaries (PBs) at the global scale. Managing absolute environmental sustainability (AES) based on PBs and EFs at the subnational level is crucial for policy insights. However, a consumption‐based AES management framework still needs to be developed. A framework, including five nexus environmental pressures embodied in the supply chain, was developed and tested in our study across China's 30 provinces to address this knowledge gap. The framework involved three steps: (a) assessing AES for five environmental pressures, (b) measuring environmental surplus and overshoot and composition of EFs, and (c) identifying priority areas for AES management. The results showed that only some provinces are sustainable for three impact‐oriented indicators, especially those with larger populations. Moreover, the embodied environmental pressure mainly flows from the Northwest to Southeast China. For two resource‐oriented indicators, over 74% of provinces are absolutely sustainable. From a nexus perspective, Shandong and Shanghai are identified as priorities for AES management due to their low IESI values of 0.32, 0.33, and 0.40, respectively, which means the worst performance. To improve their IESI, Shanghai needs to control the consumption of blue water‐intensive products, while Shandong and Henan should consume fewer CO2 emissions and N‐ and P‐loss‐intensive products. This framework can clarify subnational responsibilities of environmental overshoots, guide sustainable development, and be widely used at the subnational level in countries worldwide.

“…However, it is not clear to what extent this PPP model, which aims to reasonably share the benefits and risks of WTI delivery, can improve UWTE. Cheng et al (2023) evaluated the impact of the PPP model on UWTE, the author collected data from 1303 urban wastewater treatment PPP projects in 283 prefecture-level cities in China from 2014 to 2019 using data coverage analysis and a Tobit regression model. The UWTE was significantly higher in prefecture-level cities that implemented a PPP model in the construction and operation of WTI, especially in cities with feasibility gap subsidies, competitive procurement, privatized operations, and non-demonstration.…”

Private-public partnerships (PPPs) have become one of the leading and most effective models for investing in critical infrastructure, so the use and development of PPP models based on best practices is of particular importance in the current crisis period and during post-war recovery due to high pressure on the state budget and high risks for investment. The purpose of the study is to analyze progressive practices for the implementation of PPP projects for the critical infrastructure sectors and to develop recommendations for formulating a strategy for the usage of PPP projects in the different sectors of Ukrainian critical infrastructure. A detailed analysis of current approaches to the implementation of PPPs in the field of critical infrastructure was conducted, progressive practices of applying digitalization tools in this area were identified, and problems and prospects for their implementation were outlined. The potential factors, barriers and incentives based on regulatory, political, social, and technical factors that affect the implementation and effectiveness of PPPs in creating a modern "smart infrastructure" are highlighted. It is determined that the most important sectors for the execution of PPPs projects in most countries in recent years have been transportation, environment, education, healthcare, and telecommunications. However, the analysis of PPP projects in Ukraine concluded that the main areas of focus were the production and supply of water, gas and heat, while less attention was paid to infrastructure for education and healthcare. The article proposes strategies for the implementation of PPPs and determines the importance of each of their components for the successful implementation of PPPs, which will be relevant for Ukraine, especially at the stage of post-war reconstruction of critical infrastructure. The results of the study provide systematized information that will be useful for civil authorities, potential investors, and the scientific community.

“…For this reason, in the current research, more scholars have focused on the direction of compensation during the construction period. Relevant scholars have successively confirmed that compensation during the construction period by the government has a significant role in promoting the success rate of project operations and social benefits [38]. At the same time, they calculated and adjusted the amount of government compensation during the construction period [39].…”

Research in the field of project management has focused on recycling construction and demolition waste (CDW). However, the problem of how to compensate for the performance of CDW recycling public–private partnership (PPP) projects during the operation period has not been resolved. This paper aims to reveal the compensation mechanism during the operation period of CDW recycling PPP projects considering the two-stage performance of recycling and remanufacturing. This paper takes CDW recycling PPP projects as the research object and uses the Stackelberg game and principal-agent theory to establish and solve the master-slave game decision model of CDW recycling PPP projects. The main conclusions are as follows. When social welfare is maximized, the performance compensation coefficients in the recycling and remanufacturing stages are the same and have homogeneity. In addition, the compensation policy positively promotes the two-stage performance, social capital profit and social welfare of the recycling and remanufacturing of CDW recycling PPP projects. This paper not only broadens the application knowledge system of the relevant knowledge of project management in the field of CDW recycling but also provides new evidence for principal-agent theory from the operation stage of CDW recycling PPP projects.
