中国居民自有住房虚拟租金的一个估算

居民自有住房服务价值应纳入GDP核算,但各国对自有住房服务虚拟租金的估算方法存在差异,当前主要的核算方法为市场租金法和使用成本法。采用使用成本法对中国居民自有住房虚拟租金重新估算,发现2004—2012年间居民自有住房虚拟租金年均达3.2万亿元,最近三年年均达到4万亿。中国统计部门基于建筑成本估算的虚拟租金大大低估了居民居住支出,2004—2012年间年均低估达2.3万亿元,近三年年均低估达3万亿元。调整后的居住消费占GDP比重达到11%~14%,高于官方6%的统计数据,仅自有住房虚拟租金的重新调整就提高了4%~5%的居民消费率,随着居民收入提高,城市化进程加快,居住消费支出还将增长。     

Is Nature‐Oriented Tourism a Pro‐Environmental Practice?: Examining Tourism–Environmentalism Alignments Through Discourse Networks and Intersectoral Relationships

A key tenet of ecotourism is that interacting with nature through tourism cultivates environmental awareness and responsibility. We examine this assumption by analyzing discourse networks and organizational networks that connect tourism and environmentalism in Newfoundland and Labrador, Canada. Using a combination of interviews, field observation, and web‐based data, we ask: Is there an alignment of tourism and environmental discourse regarding human interaction with and use of coastal environments? Are there meaningful organizational ties between tourism and environmental organizations? We conclude that there is little indication that nature‐oriented tourism is working to produce substantial changes to our broader political ecology.     

Combining forecasts of electricity consumption in China with time-varying weights updated by a high-order Markov chain model

Electricity consumption forecasting has been always playing a vital role in power system management and planning. Inaccurate prediction may cause wastes of scarce energy resource or electricity shortages. However, forecasting electricity consumption has proven to be a challenging task due to various unstable factors. Especially, China is undergoing a period of economic transition, which highlights this difficulty. This paper proposes a time-varying-weight combining method, i.e. High-order Markov chain based Time-varying Weighted Average (HM-TWA) method to predict the monthly electricity consumption in China. HM-TWA first calculates the in-sample time-varying combining weights by quadratic programming for the individual forecasts. Then it predicts the out-of-sample time-varying adaptive weights through extrapolating these in-sample weights using a high-order Markov chain model. Finally, the combined forecasts can be obtained. In addition, to ensure that the sample data have the same properties as the required forecasts, a reasonable multi-step-ahead forecasting scheme is designed for HM-TWA. The out-of-sample forecasting performance evaluation shows that HM-TWA outperforms the component models and traditional combining methods, and its effectiveness is further verified by comparing it with some other existing models.     

农村土地制度改革及今后的完善思路

现代中国的农村土地制度进行了三次伟大变革,其基本成果就是现行农村土地制度;这一制度关系国之根本并具有其基本合理性,但也存在某些严重缺陷,应当以高度慎重的态度进行渐进式的改革完善。城乡二元体制是造成农村土地制度严重缺陷的首要根源,应当坚决摒弃。     

Electricity consumption and economic growth in Nigeria: Evidence from cointegration and co-feature analysis

The paper investigates the causality relationship between energy consumption and economic growth for Nigeria during the period 1980–2006. The results of our estimation show that real gross domestic product (rGDP) and electricity consumption (ele) are cointegrated and there is only unidirectional Granger causality running from electricity consumption (ele) to (rGDP). Then we applied Hodrick–Prescott (HP) filter to decompose the trend and the fluctuation components of the rGDP and electricity consumption (ele) series. The estimation results show that there is cointegration between the trend and the cyclical components of the two series, which seems to suggest that the Granger causality is possibly related with the business cycle. The paper suggests that investing more and reducing inefficiency in the supply and use of electricity can further stimulate economic growth in Nigeria. The results should, however, be interpreted with caution because of the possibility of loss in power associated with the small sample size and the danger of omitted variable bias that could result from the use of bi-variate analysis.     

Efficacy of Risk-Based, Culturally Sensitive Ogaa (Walleye) Consumption Advice for Anishinaabe Tribal Members in the Great Lakes Region

The Great Lakes Indian Fish and Wildlife Commission (GLIFWC) has produced Ogaa (walleye— Sander vitreus ) consumption advisories since 1996 for Anishinaabe from GLIFWC member tribes in the 1837 and 1842 ceded territories of Wisconsin. GLIFWC's advisory maps were revised in 2005 to address cultural sensitivities (to protect tribal lifeways), to utilize recent mercury exposure information, and to incorporate changes in advisory levels for methyl mercury. Lake-specific, risk-based, culturally sensitive consumption advice was provided on color-coded maps for two groups: children under age 15 years and females of childbearing age, and males 15 years and older and females beyond childbearing age. The maps were distributed to, and a behavioral intervention program developed for, the six GLIFWC member tribes in Wisconsin as well as member tribes in Minnesota and the 1842 ceded territory of Michigan. Tribal fish harvesters, tribal health care providers, women of childbearing age or with young children, tribal leaders, elders, and children were targeted specifically for the behavioral intervention. The efficacy of the behavioral intervention was assessed using surveys of 275 tribal fish harvesters from Wisconsin, 139 tribal harvesters from Michigan and Minnesota, and 156 Wisconsin women of childbearing age. Significant increases in the percentage of survey participants who indicated awareness of advisory maps occurred among Wisconsin harvesters (increase from 60% to 77%), Michigan and Minnesota harvesters (29% to 51%), and women of childbearing age in Wisconsin (40% to 87%). A significant increase in preference for smaller Ogaa occurred among tribal harvesters in Wisconsin (41% to 72%) and tribal harvesters in Michigan and Minnesota (49% to 71%), although not among women of childbearing age. The GLIFWC map-based advisory program did not adversely affect tribal harvest of Ogaa, which increased from 63,000 to 88,000 fish in the three states after the intervention.     

Between Neo-liberalism and Neo-indigenismo: Reconstructing National Identity in Mexico

Heightened integration with the US coupled with the rise of an indigenous movement have challenged and strained long-held images regarding the US and the indigenous within Mexico. As a result, Mexico finds itself facing the difficult task of re-evaluating and reconstructing its national identity. This paper explores the traditional images of the US and the Indian shaping national identity in Mexico and the challenges posed today by neo-liberalism and neo-indigenismo. It sets out a range of current issues, explores the linkages and contradictions, and examines the state of national reform. Fundamentally, the paper strives to raise important theoretical questions and hence set the stage for further research into these issues.     

基于生态文明观的中西消费文化比较与建设启示

生态文明关系到人类社会发展与资源环境的可持续发展,也是近年国家政策和攸关民生的焦点。从生态文明观的视角来分析中西消费文化的不同,目的就是要通过分析中西方消费思想的保守性和开放性、消费情智的感性与理性、消费对象的物质性与精神性和消费理念的对立性与统一性的区别,对我国的消费文化提出落实顶层设计、加强政府监管、重构企业文化、加强公众生态教育等方面的建设性意见。     

利率下降对我国居民跨期消费选择的影响分析

利率下降对居民跨期消费选择影响存在收入效应和替代效应.由于这两种效应对居民当期消费的作用方向完全相反,因而总效应要取决于这两种效应的强弱.对于我国中低收入居民来说,利率下降对其跨期消费选择的收入效应特别明显,替代效应则趋于零,因而降患反而会减少其当期消费数量.对于我国中高收入居民来说,利率下降对其跨期消费选择的替代效应在很大程度上被收入效应所抵消了,因而降息拉动其当期消费也不明显.为了刺激居民消费,除了实施降息政策以外,还必须采取其他政策与之配合.
