新形势下我国耕地保护的长效机制研究 总被引:1,自引:0,他引:1
耕地是人类赖以生存的物质基础,是国民经济和社会发展的宝贵资源,耕地数量的多少和质量优劣直接关系到国家粮食安全和社会稳定。因此,在新形势下,如何保护好有限的耕地资源,促进经济社会科学、合理地发展,已成为当今世界的重大课题。本文根据我国耕地减少的现实危机及原因,提出一套科学、合理的耕地保护长效机制,力求为进一步有效地保护耕地资源提供理论基础和现实途径。 相似文献

The underlying question raised in this article is: why is the accounting profession's conceptual framework (CF) so authoritative when it is conceptually incoherent? A supplementary question is how can ‘conceptually robust’ accounting standards be derived from an incoherent framework? This article draws on Page and Spira's (1999) contrasting framework metaphors to suggest that the appearance of conceptual robustness is more important than the reality, and illustrates the point with the International Accounting Standards Board's (IASB’s) progress report on its reporting performance project. Some inherent weaknesses in the move towards internationally enforceable financial regulations have been acknowledged, but this article suggests the IASB's project demonstrates two additional weaknesses: internal incoherence, and the potential for political ends to drive supposedly technical regulations. 相似文献

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low‐wage sending regions. Our new estimates of net migration for the countries of sub‐Saharan Africa show that exactly the same forces driving African across‐border migration are at work today. The results suggest that rapid growth in the cohort of potential young emigrants, population pressure on the resource base, and slow economic growth are likely to intensify the pressure for migration out of Africa and into high‐wage OECD countries over the next two decades. 相似文献

A study of first-mover effects in semi-submersible oil-drilling suggests that first-entrants in international markets maintain higher market share after controlling for market localization and life cycle. Examining only surviving entrants at a point in time inflates this pioneering-market share relationship. Pioneering has an inter-market effect on market share, greater than the intra-market effect. Multinational firms may use market pioneering to resist localization pressures and enhance survival in foreign markets. The study suggests the importance of careful first-mover identification and market definition, a wider examination of first-mover effects over multiple markets, and control for measurement timing. 相似文献

We argue that when individuals care about their consumption relative to that of their neighbours, a home bias emerges, that is investors overweight domestic stocks in their portfolios. Domestic stocks are preferred because they also serve the objective of mimicking the economic fortunes and welfare of the investor's neighbours, countrymen, and social reference group. We also demonstrate that globalization mitigates the home bias, and derive a modified international CAPM. 相似文献

In this paper, we present a two-country trade model with external economies of scale that emerge on an international level but are partially localized in each country. First, we show that the larger country exports the good produced in an industry with external economies of scale in the trading equilibrium. Second, we investigate the welfare effects of trade for the following two cases: (I) the case where external economies are completely localized in autarky; (II) the case where external economies are internationally effective in autarky. In case (II), it is shown that trade can be welfare-decreasing for both countries. 相似文献

由于各国经济发展水平、经济资源优势和经济国际化程度不同,各国都制定符合各自经济政策目标的国际投资税收政策,采取的税收优惠政策的侧重点也各不相同。跨国企业集团在制定投资战略时应注重分析各国引导投资的侧重点并充分加以利用,在投资战略选择中,必须慎重确定投资所在国的重点优惠项目或重点优惠地区,全面考虑投资国和投资所在国之间的国际税收协调性,正确认识资本投入量同税收负担与其他投资环境要素之间的关系。应以全球的观点进行国际化投资战略规划,以谋求集团整体税收负担的最小化和整体投资收益的最大化 相似文献

This paper examines a two-country, dynamic game model of pollution control in the presence of economic interactions between countries within a period, as well as the environmental interaction between periods (i.e., a change in the stock of global pollution). These economic interactions emerge because of changes in the terms of trade of polluting goods or the market share of domestic polluting industries. It is shown that if within-period externalities exist, a noncooperative equilibrium may result in a smaller stock of global pollution in the steady state than does international cooperation. Moreover, the properties of equilibrium paths depend on the direction and size of such externalities. In addition, trigger strategy equilibria that achieve the outcome of the collusive solution are examined. 相似文献
