环境是人类赖以生存的家园,城市化进程的加快与经济的高速增长对环境造成了沉重的负担,政府已高度重视,采取宣传、立法、治理等措施,保护和恢复生态环境,取得了一些成效,但存在不足。因此,加强环境保护宣传教育,提高公众环保意识;建立环保长效机制;正确处理城市化、经济发展与环保的关系;整体改善,良性循环;凸显优势,自然环境多样化;适度消费,节约型发展等,是优化环境不可缺少的重要策略。 相似文献

There is substantial research and policy interest in the relationship between firms and the natural environment, including how this relationship is influenced by regulators, international pressures, rival firms and stakeholder demands. With some exceptions, the ‘softer’ dimensions of environmental aspect management – how attitudes, beliefs and perceptions and the human factors drive corporate behaviour – have been understudied. The work that exists tends to be informal, and allows little scope for the statistical validation that is required for robust inference. This paper examines whether corporate values towards the environment affect a firm's environmental performance. It uses survey methods as well as content and discourse analyses of interview text and corporate reports and web sites to explore the links between managerial ‘mindsets’ and the environmental performance of the firms of which they are a part. Though the application is Argentina, the lessons learned can be generalized to other developing and industrialized countries. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment. 相似文献

人民币实际汇率调整趋势与中国经济转型 总被引:1,自引:1,他引:0
1978年以来的人民币实际汇率呈现出长期的贬值态势,本文结合中国经济改革的历程深入分析了实际汇率贬值的内在机制,认为市场化进程中的制度变迁和技术进步是其根本原因。而目前经济的内外失衡所引发的实际汇率和名义汇率的升值压力,本质上是深层次市场化改革推进受阻后经济结构扭曲的外在表现。本文认为,以汇率形成机制改革为主要内容的名义的市场化改革只能缓解而无法根除这种压力,推行土地、劳动力和自然资源等要素价格在内的实际的市场改革才是纠正内外失衡,缓解汇率升值压力的治本之道。 相似文献

This study examines the behavior of futures prices around stock market close before and after changes to the batching period of the stock closing call. On July 1, 2002, the Taiwan Stock Exchange expanded the length of the batching period roughly 10‐fold, from an average of 30 seconds to 5 minutes. This change presents an opportunity to analyze how a stock closing method affects the behavior of index futures prices. Empirical results indicate that an increase in the length of the batching period affects the return volatility and trading volume of index futures contracts around stock market close. Furthermore, preclose stock returns have a great impact on extended futures returns when the batching period of the stock closing call is long. © 2007 Wiley Periodicals, Inc.

One similarity among many developed economies is the predominance of cash over electronic payments in terms of payment frequency, especially for the low‐value transactions that are the bulk of retail payments. We use the Bank of Canada's 2009 Methods‐of‐Payment Survey, which collected information on consumers' payment choices through shopping diaries, to estimate a simple model of choice between cash and other payment methods. Results suggest that the main reasons cash is still a popular payment instrument in Canada, especially for low‐value transactions, are its wide acceptance among merchants compared with other alternatives, speed and ease of use, and low marginal cost when on hand.

This paper develops an endogenous growth model featuring tax havens, and uses it to examine how the existence of tax havens affects the economic growth rate and social welfare in high‐tax countries. We show that the presence of tax havens generates two conflicting channels in determining the growth effect. First, the public investment effect states that tax havens may erode tax revenues and in turn decrease the government's infrastructure expenditure, thereby reducing growth. Second, the tax planning effect of tax havens reduces marginal cost of capital and hence encourages capital accumulation so as to spur economic growth. The overall growth effect is ambiguous and is determined by the extent of these two effects. The welfare analysis shows that tax havens are more likely to be welfare‐enhancing if the government expenditure share in production is low, or the initial income tax rate is high. Moreover, the welfare‐maximizing income tax rate is lower than the growth‐maximizing income tax rate if tax havens are present. 相似文献
