基于我国彩电企业多元化战略的实证研究

文章从实证的角度，对我国彩电企业多元化发展战略与公司绩效之间的相关性进行研究，结果显示，企业总体多元化程度与资产回报率、销售利润率和净资产回报率的相关系数为负值，即多元化程度越高的彩电企业，其公司绩效越差。针对目前我国彩电企业盲目实施多元化战略的误区，文章提出了相关对策及建议。     

A change in market responses to the environmental management ranking in Japan

This article investigates stock price reactions to the release of the environmental management ranking issued by Nihon Keizai Shimbun (Nikkei newspaper) from 1998 to 2005, by using a standard event study methodology. An examination of stock price movements of the top 100 manufacturing companies reveals that stock prices during the sample period did not respond significantly to the release of the ranking within a 3-day event window. However, market responses became significantly positive after 2003, while they were significantly negative in 1999 and 2000. The stock prices of upgraded companies in particular reacted negatively before 2000, but positively after 2002. These results indicate that market reactions were changed between 2001 and 2002, when the Japanese government showed its strong commitment to environmental policies by establishing the Ministry of the Environment and signing the Kyoto Protocol, following a number of legislations.

Ecosystems,externalities, and economies

This paper incorporates an ecosystem model into a model of a simple economy. The decisionmaking agents in the ecosystem are individual organisms aggregated to the species level. A species may provide utility directly to humans, or it may provide utility indirectly because it is used either as a raw material in goods fabrication or as sustenance for other species. We describe a comparative static equilibrium of the ecosystem where species' demands for other species are equal to the supplies of those other species, and energy is conserved. The ecosystem is then embedded in the economy so that the effects of human intervention can be traced through both the ecosystem and the economy. Human intervention creates ecosystem externalities such that ecosystem equilibria are shifted and the new equilibria affect the utility or the production processes of other humans. This framework allows us to describe in principle which ecosystem services can be efficiently usurped by humans, which waste flows can be efficiently allowed into ecosystems, and which ecosystem organisms and physical attributes can be efficiently maintained.
