Our study explores how CEOs’ educational attainment affects green innovation at the enterprise level and whether CEO educational attainment and green innovation can improve enterprise performance. To date, few studies have used environmental patents of listed companies to measure green innovation at the micro-level. Furthermore, existing studies have rarely considered the heterogeneity of the enterprise type or social responsibility and institutional intervention. Thus, by using a fixed-effects model, we argue that there is a positive relationship between CEO educational attainment and green innovation. Additionally, CEO education level significantly improves enterprise performance which leads to more sustainable green patent output by influencing green innovation based on data from listed companies in heavily polluting industries in Shanghai and Shenzhen from 2010 to 2018. Moreover, the result is still held after controlling for companies’ fixed effects and using the propensity score matching method (PSM) to eliminate endogenous and sample selection bias. Specifically, we demonstrate the following findings: 1) the positive influence of CEOs’ educational attainment on green innovation behavior is more significant in private enterprises and enterprises with higher social responsibility. 2) Strict environmental legislation can make a positive impact in regions with heavy environmental pollution. 3) Enterprises’ performance and sustainable environmental innovation are promoted by the positive mechanism. Our results not only enrich the literature on the relationship between education and innovation in terms of heterogeneity but also have significance in determining how to reduce pollution from the perspective of environmental governance and enterprise management.

The psychological satisfaction of older adults is an important evaluation standard for the construction of elder-friendly cities. Meanwhile, as important space carriers carrying the travel activities and social participation of older adults, streets are also of great significance to improve psychological wellbeing. However, few studies pay attention to the street usage of aging population, especially in the context of megacities. Moreover, the previous literature rarely distinguishes the types of streets. Thus, employing a mixed approach, we investigate the relationships between street usage and psychological satisfaction for older adults. Based on the survey in Shanghai, we find that a clear role for different usage indicators in the determination of subjective psychological satisfaction of older adults. More specially, the street usage and psychological satisfaction for older adults are strongly correlated, especially for living streets. Psychological satisfaction for older adults in different types of streets is not always positively related to the positive perception of street usage. The psychological satisfaction of different streets depends on different factors. By focusing on the case of a megacity, our study emphasizes the differences between different types of streets, which will be conducive to the proposal of practical planning policies. In addition, employing mixed research methods not only explains how different street usage affects the psychological welfare of older adults on a macro scale, but also emphasizes the inner world of respondents.

The transfer of urban development goals from two-dimensional land to three-dimensional space leads to the dilemmas of the functional adjustment of partial space in the building, such as an unclear property right system, vague land financial expropriation method, uncertain economic value, etc. This study aims to understand land-development-right pricing based on spatial characteristics in spatial function regeneration. Especially, we deal with the following questions: (1) How do we identify the spatial development rights and their pricing? (2) How do we develop an effective method to evaluate the value of local spatial-oriented development rights? Answering these questions helps to establish a sustainable land finance mode, which enables the public and private sectors to share the rising value of the urban functional adjustment. Thus, employing mixed methods, the study analyzes the characteristics of property rights and the economic value of spatial-development rights. We find the following: (1) The main institutional obstacle restricting local regeneration is the inconsistency between the local spatial ownership and use right of land. (2) The technical shortcomings of land finance result from the lack of an evaluation method of the spatial characteristics. Our study motivates the transition of urban economics from a two-dimensional surface to three-dimensional spaces. Meanwhile, for countries with similar land property rights and leasing systems to China, the study also provides a useful reference to deal with the property right and land finance issues in the renewal of local spatial functions.

Investigating the mathematical and geometric principles embedded in ancient classic architecture is a significant tradition in the history of architectural development. Drawing inspiration from the modular design and creative ideology based on the geometric proportions of squareness and roundness in ancient Chinese architecture, we propose a new mode of squareness and roundness composition based on scale proportion specifically for the design of multi-story buildings. Taking Yingxian Wooden Pagoda as the case study, we not only re-evaluate the modular system and proportional rules followed in the design of the entire pagoda, but also reveal the technical approaches and geometric rules for effectively controlling the form of multi-story buildings. In particular, the mode of squareness and roundness composition based on scale proportion, utilizing a modular grid combined with squareness and roundness drawings as decision-making tools, can control the scale and proportion of buildings across different design dimensions and organically coordinate the design of multi-story buildings’ plans and elevations. Thus, it can achieve an effective balance of multi-story architectural forms. This study has potential applications in the creation of traditional multi-story buildings and heritage restoration projects, and offers valuable insights for future research on ancient multi-story buildings.

In the context of land relocation, poverty alleviation resettlement (PAR) is considered an effective approach to improve the man–land relationship and development issues. However, current studies pay little attention to PAR and its spillover effects within developed regions. Furthermore, the complete mechanism chain has received little research concentration. Thus, employing a qualitative survey, this study aims to investigate the overall mechanisms of developed regions’ PAR in the context of land relocation. The study will deal with the following questions: Why does PAR occur in developed regions? How does the resettlement approach to poverty alleviation (i.e., paths)? What are the effects of resettlement on poverty alleviation, including its own effects and spillover effects? Through answering these questions, this study will highlight PAR in developed regions and investigate the spillovers from social, economic and ecological perspectives. Particularly, a comprehensive mechanism analysis framework for PAR will be presented to motivate future studies. Results indicate that PAR is generally caused by ecological poverty alleviation, geological disaster prevention and county town urbanisation promotion and that emigration and resettlement are the paths to PAR. In addition, the direct outcome is the overall rise in the number of resettlers over time, and the spillovers show the sustainable collaboration of economic, social and ecological dimensions. These findings will influence future land reform and housing initiatives.
