Reputation mechanism is introduced and Bayesian approach is based on, in which government supervision as well as consumer purchasing behavior is taken as crucial factors to impact on the food quality security. As to the proposed quantitative indicators, government supervision includes exposure rate, fine and etc.;at the same time, consumer purchasing behavior includes consumer’s WTP for security food and consumer expectations to food safety. Taking China’s dairy industry as an example, it makes simulation by Netlog. The results show that consumer purchasing behavior alone has little effect on the dairy companies’ decision-making to be honest or counterfeiting enterprises. However, combination government supervision with purchasing behavior has great impact, and plays very good effects on food safety.展开更多

Since 1979, when China began the reform and opening up process, the economy has developed rapidly, especially the secondary and tertiary sectors. By 2005, China's GDP was 18.2321 trillion yuan, nearly 30 times that in 1979. However, the primary sector has largely been left out of this growth with its proportion in GDP dropping from 25.6 percent in 1979 to 12.4 percent in 2005.

The issue arises as to whether these improvements have been effective in reducing agency costs, and therefore enhancing firm value. The objectives of this paper is to examine the effects of governance mechanisms of dividend, types of ownership structure, and board governance on firm value. This paper utilises a panel data analysis of 403 firms listed on the Bursa Malaysia over a four-year period from years 2002 to 2005. A hierarchical regression analysis is used to test the hypotheses and the data is analysed using the generalized least square (GLS) estimation technique. Overall, the results highlight the importance of moderating role played by board governance variables with types of ownership structure to influence firm value. However, the benefits of better corporate governance through enhanced board governance are not the same across all firms since their incentives vary with respect to dividend and different types of ownership structure mechanisms.展开更多

This study examined the impact of corporate governance mechanisms on family and non-family controlled companies' performance. The sample size of this study is 730 companies listed on Bursa Malaysia from 2003 to 2007. The findings reveal that corporate governance mechanisms influence the family and non-family controlled companies' performance. But not all corporate governance mechanisms are significant. The significant variables differ between family and non-family controlled companies. Thus, regulators need to be vigilant that family and non-family controlled companies practise differently and to set different code needed for each type of families.展开更多

This paper reviews the theoretical and empirical literature on five internal mechanisms of corporate governance, namely, dividend payouts, financial leverage, institutional shareholding, board duality, and board size. These mechanisms have received the greatest deal of attention in the literature. The paper makes an original contribution to the literature as it is the first of its type, to the best of our knowledge, to provide a comprehensive idea on these five internal mechanisms of corporate governance. This study will help in investigating the relationship between internal corporate governance mechanisms and firm performance with the main aim of extending the existing literature on firm performance by empirically investigating the contribution of these mechanisms in the smooth conduct of business operations. The empirical evidence amassed favors a smaller board size, non-existence of duality and favorable dividend mechanisms as effective internal governance mechanisms affecting firm performance. At the same time, there is no conclusive evidence on the relationship between leverage and institutional ownership as internal governance mechanisms influencing agency cost and firm performance.展开更多

文摘Deliberative governance of environmental issues indicates that environmental governance has undergone a transformation from relying on government authority for solutions to reaching consensus among participants.This can be regarded as an important strategy for the structural transformation of China’s environmental governance.In this paper,the practices of environmental deliberation in China are classified into four types by the attributes of environmental issues and the relationships of participants as:response-,autonomy-,consultation-,and supervision-based.On the basis of the government’s interests and motives to engage in environmental deliberations,we analyze its practice orientations from five perspectives:scope of issues,functions,participants,procedures,and methods.Then we point out that environmental deliberations have both public and instrumental governance motives,but the governance motive,which aims for governance effectiveness and social control,is more conspicuous.We further conclude that the value pursuit of deliberative democracy for public reasons is to some extent replaced by an instrumental deliberative motive that intends to address specific environmental issues,standardize public participation orderliness,safeguard social harmony and stability,strengthen organizational functions,provide consultation on environmental policies,and promote the implementation of those policies.
