The system of State Foodstuff Security is a comprehensively systematical framework, which needs concerted support and energetic cooperation from all walks of lives. This paper analyzes the strategies for State Foodstuff Security: integrating new biological techniques with traditional methods, full utilization of soil with its protection, policies leading with market regulation, steady high yield with promoting additional value through further processing, general foodstuff production with substitute food seeking, domestic self-supply with international trade complementarities as well as short-term exploiting with long-term development on the basis of the increase of general foodstuff production capability. 展开更多

Therefore, an attempt has been made to analyze the security returns and to find out the net wealth increase or decrease to the shareholders of acquiring firms. In India, there are totally 58 manufacturing companies which have undergone mergers and acquisitions during 2000, 2001 & 2002. Thirty percentage from the total population was taken as sample size (i.e., 17 companies out of 58). The present study is mainly based on secondary data.

Good corporate reputations are critical not only because of the potential for value creation, but also because their intangible character makes replication by competing firms considerably more difficult. This paper tests the relationship between the reputation and the earnings quality. Through a partial correlation test and a regression test, I do find the evidence that the reputation is not only positively correlated with superior earnings quality, but also does have positive effect on superior earnings quality, as well as the superior total sales do in Chinese public companies. 展开更多
