本文分析了我国能源-环境-经济系统的区域特性,用能源技术模型和区域间可计算一般均衡模型相结合的方法,建立了能反映我国区域差别的区域间能源模型。在静态分析中,本文假设从价税的形式对社会各部门的二氧化硫排放以不同税率征收硫税,通过数值计算得到了分区域分部门的经济波及影响和分区域二氧化硫排放浓度;在动态分析中,本文假设从社会各部门征收的硫税在燃煤发电部门引进脱硫技术,本文给出了目前在我国燃煤发电部门已经得到利用的5种脱硫技术,分别计算了这5种脱硫技术20年间的技术普及率、环境影响、经济效果。最后,本文为实现中国能源的可持续发展提出了政策建议。 相似文献

Walter Allan 《Economic Affairs》1990,10(3):39-40
Answering multiple choice questions at 'A' Level involves different skills from ordinary questions, Walter Allan, publications director of the Institute of Economic Affairs and former teacher of economics, outlines some concepts and definitions.
The multiple choice paper is still the area which lets many students down. Economic Affairs provides 50 definitions for particular multiple choice questions which should give the student more confidence in the examination room.
Questions are normally split equally between definition and numerical questions. If you know your definitions, the numerical questions become second nature.
Multiple choice papers are difficult to revise for since you do not know which questions will arise. If you take a look at the following list, check how many concepts you are familiar with. 相似文献

In the last decade under the effects of globalization, all destinations have had experienced significant changes under different
national and/or international pressures. This is especially the case for developing countries like Turkey. With cultural,
economic and social aspects in the tourism sphere, countries are competing with each other by emphasizing their differences.
This research examines the perceptions of tourists in the Antalya Region of Turkey in terms of importance and satisfaction.
The sample consisted of 645 tourists who came to Antalya in 2001. This research presents valuable information to the tourism
sector about tourist preferences through its use of importance-satisfaction analysis. 相似文献

欧阳新年 《北京市经济管理干部学院学报》2007,22(3):20-25
以分工合作的方式进行重要的技术创新,是新形势下企业技术创新的重要战略选择。合作技术创新的成功实现,关键在于选择恰当的合作创新形式和处理好合作各方的利益关系。本文介绍了企业合作技术创新中的技术转让、合作开发、技术联盟、创新网络、共建实体等五种模式,并对其优缺点进行了比较,提出了对这些模式选择的思路;依照合作创新风险共担、利益共享的原则,根据合作的紧密程度,分别分析了合作创新的风险,并提出了合作各方利益分配的方式方法。 相似文献

This paper is directed at understanding the factors which caused mortgage demand to fluctuate to the degree witnessed in the 1980s. We model the mortgage choice decision as involving simultaneous options on both the term and the amortization choice, by cost minimizing risk averse borrowers. The model is estimated using a bivariate ordered probit methodology. An extensive database containing details on the financial and demographic characteristics of households is used. We find that, contrary to the dominant model of mortgage demand, borrowers react to market conditions in a risk averse and cost minimizing manner. 相似文献

Using a nested multinomial logit model (NMNL), this paper estimates the choice probabilities and demand elasticities of various modal alternatives for Mumbai using 1990 trip origination and destination data. The results indicate that with an increase in the cost of private transit system, market share is reduced. The result of this experiment is highly elastic private commuting mode demand. In addition, reduction in the market share of own vehicles is larger than that of hired vehicles. The increase in the cost of mass transit system reduces its share but is inelastic. Decrease in the market share of one mode is accompanied by increase in the market share of others. Income has a positive effect on the market share of private transit modes, particularly on the own vehicles' share. Other explanatory variables such as distance have a negative effect on mass transit system and duration has a negative elasticity for all modes of transportation. 相似文献

参与式预算在中国:现实问题与未来选择 总被引:3,自引:0,他引:3
伴随基层民主改革的深化,参与式预算日益引起社会各界的广泛关注.当前在"自上而下"的部门预算改革和"自下而上"的参与式预算改革两种发展路径中,县级预算处于其交汇点.参与式预算对于经济欠发达地区的公民而言,仍旧具有某些"奢侈品"的色彩,在基于本土化的自主创新过程中,参与式预算需要按照"三部曲"的改革思路来加以推进. 相似文献
