This paper aims to investigate the fretting wear mechanism of an Al-Li alloy at room temperature, the tangential fretting wear tests were carried out.

The effects of displacement amplitude and fretting frequency on the tangential fretting wear characteristics were mainly investigated. The experimental data obtained are analyzed and compared.

The results indicated that the fretting friction coefficient increased with the increase of displacement amplitude. As the displacement amplitude increased, the wear scar morphology changed significantly, mainly in terms of delamination debris and furrow scratches. The wear mechanism changed from initial mild wear to more severe oxidative wear, adhesive wear and abrasive wear.

This paper extends the knowledge into mechanical tight connections. The conclusions can provide theoretical guidance for the fretting of mechanical tight connections in the field of automotive lightweight and aerospace.

The purpose of this paper is to estimate the elasticities of demand for different dairy products, such as fresh milk, powdered milk and yoghourt, in urban China.

The household survey data are drawn from the annual Urban Household Survey in a Chinese province from 2007 to 2009 by applying a three-stage budgeting approach with zero consumption.

The major findings show that fluid milk is the most popular dairy product among urban households in Guangdong province, China. Demand for fresh milk is price elastic with the highest value being −1.043, indicating that price-cutting promotion programs could be carried out by dairy enterprises to increase dairy consumption. With improvements in the living standards, the demand for dairy will lead to an expansion in the size of the dairy market and will simultaneously open up new development opportunities for dairy enterprises.

This study adopts an Almost Ideal Demand System model inserted into inverse Mills ratios in the third stage to resolve the common problem of obtaining censored data on zero consumption observations. The research findings will provide a reference for policy makers and for enterprises in developing some price-cutting promotion programs.

Much work has been done on the optimization of the discrete variable structure design. In order to handle the optimization problem effectively, the related theories, methods, and other beneficial results were summarized. On the basis of analyzing the predecessors' research, the development direction was introduced. Then, some practical methods, including their improvements, for discrete structural optimization were analyzed. Finally, the Ant Colony Optimization algorithms were shown as promising methods. This work has significance in theory and practice for the development of structural optimization.

This paper aims to examine the internal logical relationship between two intergenerational inheritance ways of passing property rights and residual control rights (RCR) and to construct a conceptual model comprising transfer elements, paths and timing of succession in this process.

Driven by the cases of Haixin, Tianyijiao and Changhe Group, this paper applies research methods of copying and expanding analysis logic, progressive deduction, content analysis and comparative research based on the perspective of HeXie theory to explore the deep interrelation of transfer elements, paths and timing during family business succession.

The findings present that the content of intergenerational inheritance of a family firm is the inheritance of property rights and RCR. First, the inheritance of property rights is a static inheritance of time-point delivery, whereas the inheritance of RCR is a dynamic inheritance process for a period of time. Second, the inheritance of property rights and RCR are not independent; only a “HeXie” succession of both rights can realize a successful inheritance of family firms.

This paper constructs the paths and timing model of intergenerational inheritance of property rights and RCR in family firms. This paper integrates the current literature studies on the family inheritance of property rights and RCR and explains their internal mechanisms. This paper also provides a theoretical foundation and empirical evidence for family business transitions in the business world.

Prior research shows that managers with lower ability release less accurate management earnings forecasts and have more earnings restatements, lower earnings persistence and lower quality accruals estimations. Yet, whether the impact of managerial ability (MA) on financial reporting can be extended to the narrative section of firms' financial disclosures needs to be theoretically and empirically examined. The authors theorize in this paper that managers with low ability opportunistically inflate the tone to increase outsiders' perceptions of their ability. The authors also examine the relation between MA and the informativeness of tone to predict future firm performance and explain investors' reaction at earnings announcement.

The authors collect 24,000 earnings press releases of 1,149 distinct firms between 2004 and 2013. Content analysis is used to proxy the tone of the disclosures. The authors use the score developed by Demerjian et al. (2012) to measure MA. The authors then employ panel data regressions to examine the impact of MA on disclosure tone.

The authors find that low-ability managers inflate the disclosure tone to positively influence labor market's perceptions about their ability. This effect is magnified for younger and shorter-tenured managers, for firms with more intense monitoring and during bear markets. The authors also find that the tone of earnings press releases of low-ability managers results in a lower stock price reaction. Supplementary analyses show that the results do not only hold for the tone, but also can be extended to other linguistic features such as the numerical intensity and the readability of earnings press releases. The results are robust to alternative library specifications and other corporate disclosures such as CEO letters to shareholders or 10-K filings.

The paper shows that managers worry about how firm performance influences the labor market assessment of their ability. In particular, the authors find that managers of low ability are willing to opportunistically manipulate the content of corporate disclosures to improve this perception and build their reputation.

The authors contribute by providing theoretical and empirical evidence on how managers attempt to steer assessments of their ability by manipulating corporate disclosures. Consistent with prior business research suggesting that one's ability is a key feature that affects managers' propensity to engage in ethical practices, such as tax avoidance or manipulation of financial information, this study shows that less able managers tend to inflate the tone of the earnings announcements and that this ability-driven bias is likely to be magnified by career concerns.

This paper explores the contextual factors involved in the development and application of paradigmatic theories in general, and the application and development of Agency Theory in the Chinese context in particular.

Referring to four templates for the design of conceptual papers as outlined by Jaakkola (2020), i.e. theory synthesis, theory adaptation, typology and model – we adopt an approach combining theory/literature synthesis and model establishment. Based on a thorough analysis and discussion of the literature on the topics of “context effect “, “interface between theory and context”, “special characteristics of Chinese context” and “invalid application of Agency Theory in a Chinese context”, we use Agency Theory as the lens to discuss the importance of context in applying and developing paradigmatic theory specifically. We start from the contextualization of Agency Theory and then explore approaches to theorizing the Chinese context by developing a conflict coefficient model.

First, the application validity of paradigmatic theories is not sustainable; contextual factors are critical in applying and developing not only propositional but also paradigmatic theories, such as Agency Theory. Second, the Chinese context requires special attention when applying paradigmatic theories originating from Western countries. Third, the traditional application logic of Agency Theory is invalid in the Chinese context due to the coexistence of principal-agent conflicts (PAC) and principal–principal conflicts (PPC), and changeable dominance status of two conflicts according to the contexts. Based on these observations, a model of contextualization theory of PAC and PPC (i.e. conflict coefficient model) is developed from a dynamic perspective, which connects the separated situation states and allows the identification and measurement of the relative severity of the two types of agency conflicts.

Practitioners can also use this model to identify and measure the relative strength of the two conflicts and determine the direction of control and improvement. Moreover, analysis of Chinese context and agency problems of Chinese firms also has great practical significance considering the increased importance of the Chinese market and the increasingly important role played by Chinese firms in the international economy in general, and in specific host countries in particular.

First, in general, this study expands Whetten's (2009) study of the interface between theory and context. It specifically discusses approaches to considering contextual factors in the development and application of the relatively overlooked paradigmatic theories, using traditional and widely used Agency Theory as a lens. Our study suggests that typical Agency Theory, developed based on Western-centric assumptions, does not completely hold in the context of Chinese business practices because of different cultural, legal and governance realities. Second, it improves and extends the application of Agency Theory by proposing the new perspective that PAC and PPC coexist in specific contexts and positing that the relative severity of two types of agency conflicts depends on the context variables. Third, it puts forward a conflict coefficient model offering a more comprehensive, intuitive and quantifiable method for comparing the extent of the two conflicts in different scenarios, providing a reference for empirical studies of corporate governance.

The purpose of this paper is to analyze several measures which the government of the People’s Republic of China (PRC) has adopted to curb corruption and to make recommendations to curb the spread of corruption.

The study is based on the analysis of government policy documents and reports, and statistical data on anti-corruption measures in China.

During the past ten years, the government of the PRC has adopted these anti-corruption measures: first, increasing the ability to handle cases for deterring corrupt officials; second, improving the work style of officials and prohibiting them from enjoying special privileges, and promoting moral behavior among them; third, reforming the economic and political system to reduce corruption opportunities; and fourth, reforming the Central Commission for Discipline Inspection (CCDI) to more effectively handle corruption cases. Nevertheless, in despite of these anti-corruption measures, there remain serious challenges for reducing corruption stemming from an irrational system of administrative reform and balancing the relationship between the CCDI and the judiciary departments to enhance the professionalism and efficiency of the anti-corruption agencies, which continue to constrain China’s current anti-corruption efforts. Therefore, the Chinese government should take a top-down approach, analyze the characteristics and trends of corruption in the new era, strengthen the institutional structures, and strive to suppress the spread of corruption.

This paper will be useful for those scholars, policy-makers and anti-corruption practitioners who are interested in China’s anti-corruption measures.

International research has found that Homeowners Association (HOA) is capitalized in housing price in the West. Is that result applicable in Chinese cities? In China there is also widespread applause for HOA. Will that leave trail in the housing market? This paper aims to answer these questions by presenting empirical evidence from 113 private gated communities in Chongqing, China.

The data set comes from three different sources including a telephone survey. The research methodology includes hedonic models with an endogenous dummy variable of the presence of HOA in a community.

HOA is not capitalized in housing price.

The empirical finding helps to explain why about 80% of private communities in big Chinese cities have not formed an HOA.

This is the first empirical study on HOA capitalization in housing price in China.

This case reviews the development of Dianping. After seeing Zagat's unique business model in the United States, founder Zhang Tao found that he could bring it to China and bring about local innovation. At the beginning of its establishment, the collection and promotion of comment content was the major challenge for Dianping. At the same time, Dianping faced legal issues. To solve these problems, the review mechanism of Dianping was designed to a certain extent to ensure the fairness of the review. With the advent of the mobile Internet era, Dianping began to develop a new business model. Relying on its high-quality “word-of-mouth” content and mass basis, Dianping launched group buying, online restaurant ordering, and other businesses. Dianping has always been open to strategic partners. Since 2015, Dianping has undergone historical changes, merging with Meituan. Since then, Dianping has continuously adjusted its business and organizational structure to maintain its competitiveness. Gradually, Dianping has changed from an independent business entity into a business unit of Meituan.
