The research of Chinese karst ecological hydrology

1. Introduction The area of carbonate rocks protruding through the soil level in China is 9.07*105km2. According to the area of carbonate rocks stratum protruding through the soil level, it is 2.06*106km2. With the buried carbonate rocks stratum of the different depths, its total area can reach 3.443*106km2, ap- proximately accounting for 1/3 of the national terri- torial area. Chinese carbonate rock is mainly distributed to the south of the latitude belt of Tianshan Mountain – Yinshan Moun…     

The Change of Ecological Footprint and Its Effect on Sustainable Development in Beijing of China

Speeding up the environmental protection and construction is one of the major issues in ＂Greener Olympic Games＂ held in Beijing in 2008. Making a thorough study to find out the reliable measures to ecological resumption in Beijing has an important scientific and practical significance. It can provide scientific basis for making a better decision for ＂Greener Olympic Games＂ held in capital Beijing and development in harmony for society and economy, as well as management for ecological environment. By studying of change of ecological footprint from 1990 to 2003 in Beijing, the paper shows that ecological footprint per capita has a strong relativity with population and GDP, and both of the correlation coefficient between them is about 0.92, as well as the fossil energy land has a position in the lead in ecological footprint items. The study also shows that the ecological capacity per capita in Beijing occupied about 1.25% in global ecological capacity per capita. Began 1990, the ecological deficit in Beijing was about 0.72 hm2, which is at strong unsustainable development at present. Finally, the paper suggests social and economic structure should be adjusted as soon as possible, resources should be strengthen sustainable used and population increasing should be controlled strictly, as well as arable land also should be under control used for built-up areas. Simultaneity, the utilizing ratio of energy sources should be increased, and the consumption of energy sources and ecological deficit in Beijing should be reduced in order to speed up the society and economy development in harmony and sustainment.     

Régulation School and environment: Theoretical proposals and avenues of research

The article explores the relevance of a particular approach of the institutionalist movement, régulation theory, to deal with the relationship between the economy and the environment. Régulation theory, which appeared in France at the end of the 1970s, is mainly interested in macroeconomic issues. In contrast, until now it has tended to neglect environmental questions. By taking several key concepts of this theory (accumulation regime, mode of régulation, institutional forms), we have sought to assess its significance vis-à-vis the environmental field. More precisely, from the perspective of establishing an environmental regulationist theory, we propose considering the economic relation to the environment as the articulation of three forms: a transhistorical form, a general capitalist form and a specific capitalist form, the latter being variable in capitalist time and space. We give several illustrations of the variability of the relation to the environment, depending on the different accumulation regimes and the different modes of régulation. Two principal avenues of research are proposed: historical analyses for given economic areas, and comparative analyses relating in particular to different capitalist areas.     

Evaluating investment projects in the presence of sectoral linkages1

In this paper we develop a framework to assess the economic impact of foreign investment projects. If investment projects interact with other industries in the host economy, either by buying inputs locally or by selling their own product to local downstream firms, they can create sectoral linkages. The expansion of upstream and downstream industries can feed back to the project's own industry leading to a further expansion of the local industry. We study the circumstances under which investment projects lead to the creation of sectoral linkages and characterize the factors that determine the project's welfare impact. We link analytical findings to case studies undertaken for the EBRD.     

民族文化变迁对生态环境保护的影响——以云南为例

我国西部生态环境保护一直是各学科关注的焦点问题,但从生态环境保护的民族文化内在驱动力这一重要角度进行研究的较少。实际上,环境保护的主体是当地居民,而环境保护观念主要受到传统民族文化的影响。本文通过对云南民族文化变迁的分析,指出了对云南民族生态文化产生负面影响的因素主要来自三方面:汉文化、近现代文明、地域权力变更与“左”倾思想。最后,探讨了解决云南民族文化与生态环境保护之间的摩擦的途径。     

Investment opportunities and cash holdings of firms: an empirical study on Korean firms

We find that the cash flow sensitivity of cash holdings of firms whose investment opportunities are lower is significantly higher by examining a panel data of 898 Korean firms for 1999–2014. The cash flow sensitivity of investment is also found to be lower in case of low investment opportunity. Both findings suggest that firms decide to hold cash in response to an increase in cash flow when they do not have a good investment opportunity. Precautionary motive because of financial constraints and uncertainty, and agency problems, however, are not associated with the cash flow sensitivity of cash holdings. These findings imply that it is necessary to develop new investment opportunities to encourage firms to spend more cash in Korea.
