Although an important facet of modernist architecture in which function plays a prominent role, building flexibility is not entirely a new concept. Its relevance transcends generations, allowing space and structure to evolve through time. This paper investigates the relationship among main building structures, infill elements, and space by studying examples in ancient Chinese architecture. It reveals the role of building owners, users, and craftsmen from a survey of historical documentation. In studying these examples, it is concluded that craftsmen in ancient China were involved not only during the construction phase but throughout the period of use as well. Thus, in select cases, the relationship between craftsmen and owners or users had been preserved for generations. Finally, this paper suggests potential strategies for the building industry and technology in the move towards sustainable development.

The purpose of this paper is to provide the historical background of genealogical records and analyze the value of Chinese genealogical research through the study of names and genealogical resources.

The paper examines the historical evolution and value of Chinese genealogical records, with the focus on researching the Islamic Chinese names used by the people living in Guilin. The highlight of this paper includes the analysis and evolution of the Islamic Chinese names commonly adopted by the local people in Guilin. It concludes with the recommendations on emphasizing and making the best use of genealogical records to enhance the research value of Chinese overseas studies.

The paper covers the history of Islam and describes how the religion was introduced into China, as well as Muslims' ethnicity and identity. It also places focus on the importance of building a research collection in Asian history and Chinese genealogy.

This research study has a strong subject focus on Chinese genealogy, Asian history, and Islamic Chinese surnames. It is a narrow field that few researchers have delved into.

The results of this study will assist students, researchers, and the general public in tracing the origin of their surnames and developing their interest in the social and historical value of Chinese local history and genealogies.

The study of Chinese surnames is, by itself, a particular field for researching the social and political implications of contemporary Chinese society during the time the family members lived.

Very little research has been done in the area of Chinese local history and genealogy. The paper would be of value to researchers such as historians, sociologists, ethnologists and archaeologists, as well as students and anyone interested in researching a surname origin, its history and evolution.

Understanding farmers’ preferences for crop insurance attributes is crucial in designing better insurance products and guiding government policies but such research is lacking, particularly in developing countries. The paper aims to discuss these issues.

This study uses a survey featuring a discrete choice experiment and policy simulation.

Overall, crop insurance has positive values to farmers, although preference is heterogeneous based on socioeconomic characteristics and risk position. Policy simulation confirms the roles of liability in strengthening insurance participants’ welfare and premium subsidy in encouraging participation. Introducing one more product into the market can accommodate farmers’ diverse needs and lead to increases in both aggregated social welfare and participation while maintaining the current level of government expense in subsidy – a potential Pareto improvement.

Methodology employed is not the most novel in the choice experiment literature as many of the advances in choice experiment design could not be applied due to the actual condition in rural China and Chinese farmers’ capability in understanding the experiment.

The results indicate that the current single-product market structure using “low liability with high premium subsidies” cannot accommodate the diverse needs among farmers. Providing more varieties of liability-subsidy combinations, e.g. a high liability with low premium subsidy insurance product, can substantially improve participants’ welfare with little impact to the probability of participation.

The authors believe that this is one of the very few studies that that analyze farmers’ preferences and willingness to pay for the attributes of crop insurance products. It also shows how crop insurance product design can build upon farmers’ choices to achieve a potential Pareto improvement in aggregated social welfare in the context of a fast-developing crop insurance market.

Since 1999, China has undergone reform of its healthcare system. City‐based social health insurance (SHI) is the primary form of current health insurance, supplemented by various commercial health insurance programs. The rural new cooperative medical system (NCMS) was introduced in 1993 and extended to cover the whole of rural China in 2003.

The paper developed a theoretical model for consumer demand of medical services and health insurance based on an expected utility framework with a two‐stage decision under uncertainty. The model is then applied to current health insurance systems in China for urban citizens and rural residents separately. Least square and logistic regressions are employed.

The major results are that although the factors driving the decisions on health insurance participation are basically the same for rural and urban citizens, the participation levels are quite different. The major difference is that urban SHI has higher coverage and urban citizens have higher income, resulting in a much larger urban medical expenditure.

The empirical analysis reveals that health insurance programs have played an important role in the healthcare expenditure for urban residents, while the NCMS has not made a significant impact towards increasing the ability of rural residents to seek more medical services, based on data at 2004.

This is the first paper employing a health production theory on China's new urban and rural healthcare programs.

This study aims to elucidate how different relationship investment efforts by a service firm affect its customers’ perceived relationship investment; to determine how perceived relationship investment influences various dimensions of relationship strength; and to explore the moderating effects of customer innovativeness and complaint propensity on the relationship between the perceived relationship investment and relationship strength.

To minimize common method variance, data were collected from pairs of life insurance agents in China and their clients using self-report questionnaires. Hypotheses were tested using structural equation modeling.

The results indicate that customers value financial effort most followed by social effort and structural effort. Perceived relationship investment influences the affective strength most strongly, followed by cognitive strength and conative strength. Customer innovativeness and complaint propensity both moderate the effectiveness of perceived relationship investment in influencing two of the three dimensions of relationship strength.

This study is among the first to specify how service employees can guide consumer perceptions of relationship investment by applying three types of relationship investment effort. The impact of perceived relationship investment on different dimensions of relationship strength was assessed to demonstrate how service providers can benefit from investing in building consumer relationships. The moderating impact of consumer innovativeness and of complaint propensity was quantified. The research findings have important implications for managing different relationship investment as well as recruiting and training service employees.

The goal of this chapter is to respond to the theoretical inquiries by scholars who are interested in how the public–private partnership (PPP) models adapt to China’s context where political power dictates economic strategies. We also want to provide suggestions to policy designers who aim to promote a sustainable investment environment for domestic and international investors. We review the literature that explains the upside and downside of PPP projects in contemporary China. (1) We classify the trajectory of PPP evolution into four phases, i.e., emergence, growth, recession and revival. (2) We note that private companies take a disadvantageous position in the partnership compared with governments and state-owned enterprises because of a lack of specialized legislation, unequal competition between private companies and state-owned enterprises and the opposition from the civic society. (3) We identify political risks as the most influential risks. Political risks also lead to the misallocation of other risks between public and private parties that contributes to the high failure rate of China’s PPP projects. Based on these findings, we recommend governments to draft specialized legislation, stabilize the political environment and provide favourable subsidies to local governments to limit the risks involved in PPP projects. We also advise private enterprises and state-owned enterprises to focus on negotiating over task and risk division with governments when they make decisions to participate in PPP projects. This full review of studies on PPP development in China provides reliable recommendations to scholars, governments and enterprises.

This paper aims to explore the influence of founder shareholders’ resources on the allocation of control rights from the perspective of incomplete contract theory and resource-based theory.

This paper analyzes newspaper materials with NVivo11on a case of battle for corporate control in Chinese top-listed company-Vanke Group.

The research shows that human capital is the key resource and the holding proportion of financial resources directly affects the allocation of control rights. At the same time, social capital is unstable and easily broken. At last, institutional environment also affects the degree between the relationship of founder shareholders’ resources and the allocation of control rights. The influence of founder-shareholder resources on the allocation of control rights follows the path of “crisis – founder-shareholder’s resources – founder’s ability - allocation of control rights.”

This study only selects the financial capital, human capital and social capital of Shi Wang, the founder of Vanke, as the analysis object. The study can expand the types of founder shareholder resources to verify and enrich the conclusions.

The current theoretical research in the literature focuses on the necessity of equity and shareholder’s resources versus the control rights. Some key factors and mechanism on the relationship have not been fully clarified. The results of this paper not only extend the combination research of social network and corporate governance, but also provide enterprise founders with references for making reasonable decisions during control battle.

This paper applies a volume-price probability wave differential equation to propose a conceptual theory and has innovative behavioral interpretations of intraday dynamic market equilibrium price, in which traders' momentum, reversal and interactive behaviors play roles.

The authors select intraday cumulative trading volume distribution over price as revealed preferences. An equilibrium price is a price at which the corresponding cumulative trading volume achieves the maximum value. Based on the existence of the equilibrium in social finance, the authors propose a testable interacting traders' preference hypothesis without imposing the invariance criterion of rational choices. Interactively coherent preferences signify the choices subject to interactive invariance over price.

The authors find that interactive trading choices generate a constant frequency over price and intraday dynamic market equilibrium in a tug-of-war between momentum and reversal traders. The authors explain the market equilibrium through interactive, momentum and reversal traders. The intelligent interactive trading preferences are coherent and account for local dynamic market equilibrium, holistic dynamic market disequilibrium and the nonlinear and non-monotone V-shaped probability of selling over profit (BH curves).

The authors will understand investors' behaviors and dynamic markets through more empirical execution in the future, suggesting a unified theory available in social finance.

The authors can apply the subjects' intelligent behaviors to artificial intelligence (AI), deep learning and financial technology.

Understanding the behavior of interacting individuals or units will help social risk management beyond the frontiers of the financial market, such as governance in an organization, social violence in a country and COVID-19 pandemics worldwide.

It uncovers subjects' intelligent interactively trading behaviors.
