东祁连山农牧区生态承载力及可持续性分析

运用生态足迹模型对位于祁连山东段农牧区的天祝县进行了生态承载力状况的分析。结果表明,天祝县2008年的生态足迹未超过生态承载力,出现生态盈余,生态环境容量尚能承载环境负荷。而对2000---2008年生态足迹及生态承栽力动态变化分析结果表明,天祝县生态盈余呈持续下降趋势,表明该区生态可持续性的持续下降状况。针对这一状况,根据该区生态资源状况的基本特征,提出生态经济系统可持续性建设的建议。

Trade Liberalization and Pollution: An Input–Output Study of Carbon Dioxide Emissions in Mexico

This paper examines the environmental effects associated with Mexico's participation in the North American Free Trade Agreement (NAFTA). The objective is to provide quantitative estimates of carbon dioxide (CO₂) emissions from changes in the level and structure of production and consumption activity in Mexico following a liberalization of trade. The quantitative analysis was performed using input–output methods with fuel use modifications to account for CO₂ emissions before and after NAFTA's implementation. As a result of NAFTA, CO₂ emissions are expected to increase from the anticipated increase in the size of the Mexican economy. While total emissions increase as a result of tariff elimination, there is also a shift in the structure of production and final consumption away from those sectors that are the most C02 intensive.     

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.     

中国电力行业碳排放配额分配——基于排放绩效

阐述了我国二氧化碳排放现状;预测了2015年、2020年我国二氧化碳的允许排放量,测定出电力行业的二氧化碳排放控制目标,并将其分解到不同容量等级的发电机组中;基于排放绩效方法,对2015年、2020年不同火电厂的碳排放配额进行了分配;最后给出在我国推广排放绩效机制所需的政策支持。研究结果表明,利用排放绩效机制能有效分配碳排放配额,控制二氧化碳排放量,是电力行业实施碳减排的一种有效机制。     

基于可计算的一般均衡模型的我国碳税政策“双重红利”研究

建立了分析我国减少二氧化碳排放而征收碳税的可计算的一般均衡模型,分析碳税政策的双重红利。结果显示:为减少二氧化碳排放而征收碳税,对社会经济变量将造成一定的负面影响。保持财政中性,在征收碳税的时候,减少居民或者企业间接税,都可以在减少二氧化碳排放量的同时提高社会福利或者保持社会福利变化不大,实现碳税的双重红利。但是在保持财政中性,在征收碳税的同时减少企业所得税,虽然减少了二氧化碳排放量,居民的社会福利却有了更大程度的下降。     

澳门旅游生态足迹研究

澳门小城以狭小的地域面积承载着规模巨大的旅游活动,蓬勃兴旺的旅游产业已成为澳门社会经济的命脉,并为世人所瞩目。然而,旅游业以旅游目的地的生态环境与自然资源为基础,并在发展过程中不可避免地对二者产生压力与负面影响。运用生态足迹的理论与方法,测算出2009年澳门不可转移之旅游生态足迹为18 300.891gha,是旅游生态承载力的3.29倍,旅游生态赤字为12 737.584gha,结果发现澳门的旅游生态足迹经济效率较高,但旅游活动正在过度消耗资源环境,使当地的旅游发展不具备生态可持续性,因此相应的改进措施应早日出台,以实现资源保护与旅游发展的平衡,促进旅游业的持续发展。     

空间溢出、双向FDI与二氧化碳排放强度

基于文献综述发现双向FDI(外商直接投资和对外直接投资)对碳排放强度的影响可能同时具有"污染光环效应"和"污染避难效应".因此,选择2005—2017年中国30个省市(因数据缺失,不包括西藏地区和港澳台地区)的面板数据,通过莫兰指数(Moran's I)对中国外商直接投资、对外直接投资和二氧化碳排放强度的空间集聚特征进行刻画,并构建空间计量模型实证研究中国双向FDI对二氧化碳排放强度的影响效应.研究发现:中国二氧化碳排放强度与双向FDI都存在显著的空间正相关特征;中国双向FDI对本地区二氧化碳排放强度的影响效应均显著为正;中国双向FDI的空间溢出效应显著抑制中国二氧化碳排放强度增加.最后,提出了合理利用双向FDI的政策建议.     

Design considerations for neyman-pearson and wald hypothesis testing

Summary The Neyman-Pearson Lemma describes a test for two simple hypotheses that, for a given sample size, is most powerful for its level. It is usually implemented by choosing the smallest sample size that achieves a prespecified power for a fixed level. The Lemma does not describe how to select either the level or the power of the test. In the usual Wald decision-theoretic structure there exists a sampling cost function, an initial prior over the hypothesis space and various payoffs to right/wrong hypothesis selections. The optimal Wald test is a Bayes decision rule that maximizes the expected payoff net of sampling costs. This paper shows that the Wald-optimal test and the Neyman-Pearson test can be the same and how the Neyman-Pearson test, with fixed level and power, can be viewed as a Wald test subject to restrictions on the payoff vector, cost function and prior distribution.
