Effectively enhancing perceptions of cultural ecosystem services: A case study of a karst cultural ecosystem.

The role of cultural ecosystem services (CES) is vital to consider when developing ecological sustainable development policies that can improve the well-being of humans. Research on CES has increased in recent years; however, few studies have explored the complex mechanisms driving perceptions of CES and the factors influencing those perceptions. In areas with unique landforms and fragile ecological environments, this type of research is difficult and rare. To address this research gap, this focuses on a typical karst area Guilin Xingping in China, evaluating residents' perceptions of local CES, and applying qualitative comparative analysis (QCA) to explore the driving mechanism behind those perceptions. We found that the satisfaction of material needs is a prerequisite and basis for further improving residents' spiritual perceptions and pursuits. Residents' socio-economic level, understanding of resource importance, and economic value determine whether residents can fully perceive the value of CES. Optimizing the ability of managers, improving relevant systems, and improving the experience with and understanding of ecosystems have a more than 50% probability of improving perceptions related to CES. The research shows that the combination of multiple antecedents can achieve a high level of perceptions related to CES. Managers can refer to the best path for policy regulation based on the actual situation. Finally, this study provides a new policy scheme for promoting ecological sustainable development and improving residents' well-being, and can provide insights to inform the sustainable development of other karst areas.

Is the "pollution haven hypothesis" valid for China's carbon trading system? A re-examination based on inter-provincial carbon emission transfer.

In recent years, China had released various environmental regulations in order to respond climate change and corresponding environmental issues. However, due to imbalanced economic development and industrial structure, different Chinese regions had different enforcement levels on environmental regulations, which led to the regional transfer of pollution-intensive industries. To study the regional disparities on carbon emission transfer, this paper used the propensity score matching-difference in differences method (hereinafter abbreviated as "PSM-DID") to evaluate the mechanism between carbon trading pilot policies and the transfer of pollution-intensive industries. Panel data on 30 Chinese provinces were used to test the validity of the "pollution haven hypothesis," covering the period of 2010-2018. The empirical results showed that under the constraints of established environmental regulation, the pilot policy promoted the transfer of pollution-intensive industries to a certain extent and verified the "pollution haven hypothesis"; the proportion of the secondary sector and energy industry in the pilot areas had been reduced after the pilot policy; on the contrary, the technical level and the economic development level of the pilot provinces and cities had been further improved.
