关于消费者“绿色消费”的几点思考

我国是一个人均资源极其贫乏的国家,为缓解我国资源全面紧张的状况,实现社会的可持续发展,必须要使消费者树立正确的"绿色消费"观念,提高消费者的消费水平,引入循环经济模式并上升到法律规制的高度,加强循环经济立法,实现我国环境保护基本国策,促进我国循环型社会的建立和发展.     

构建有中国特色的可持续发展住房消费模式

21世纪,我国城市化和房地产业进入加速发展时期,亟需构建有中国特色的可持续发展住房消费模式。构建这一模式关键是现阶段在我国倡导适度消费和梯级消费,大力发展节能省地住宅。为此,在政策和措施上要构建鼓励居民住房梯度消费的政策体系,抓紧完善节能省地的经济政策,重视生态环境保护,在全社会大力倡导科学的消费观念。     

Internet use and consumption diversity: Evidence from rural China

The Internet is integral to modern living. While the Internet is ubiquitous in China's urban areas, its uptake is still lagging in the country's rural regions—the development potential of the Internet remains untapped, and despite China's steep economic growth during the 21st century, the living standards in its rural regions remain low. The Internet can accelerate rural development in China. This study is focused on analyzing whether and to what extent Internet use affects consumption diversity, an indicator of the quality of life, in rural China. To this end, we employ the instrumental-variable-based two-stage endogenous treatment regression model to analyze the 2018 China Family Panel Studies survey data. The modeling approach allows us to account for the endogeneity of Internet use. The results show that consumption diversity is positively associated with Internet use. Furthermore, it rises with household income, household size, and wealth. Whether the Internet is accessed via smartphones or computers has no bearing on household consumption diversity. We also find that education, household income, and wealth increase one's predicted probability of using the Internet. The results also point to regional differences in consumption diversity and the likelihood of using the Internet.

ANALYSING IMPLICATIONS OF LIMITED WATER AVAILABILITY FOR GREAT BARRIER REEF CATCHMENTS

Dependence on water is one of the factors that can determine regional vulnerability in Australia. Climate change is predicted to change rainfall patterns in the Great Barrier Reef (GBR) region, and scarce water resources have the potential to make regional Queensland economies increasingly vulnerable. Understanding which economic sectors depend on water as an input factor helps in understanding sectoral and regional vulnerability, and thus in guiding regional policy aimed at structural change. Using a regional Queensland Input–Output (IO) model, this paper integrates water consumption of the GBR region and then compares monetary IO multipliers with water consumption multipliers. We argue that these IO multipliers can inform regional decision makers about potential future regional vulnerability by taking into account limited water resources.     

我国港口能源消耗统计及分析计算方法研究

从港口能源消耗统计指标及统计口径入手,采用典型抽样的方法采集能耗数据,根据实际情况将沿海和内河港口分为两部分,分别采用不同的方法进行计算,实现了我国港口行业能源消耗的统计分析计算,并以2005年为例对该分析计算方法进行实例验证。     

A game-theoretical model of the landscape theory

In this paper we examine a game-theoretical generalization of the landscape theory introduced by Axelrod and Bennett (1993). In their two-bloc setting each player ranks the blocs on the basis of the sum of her individual evaluations of members of the group. We extend the Axelrod–Bennett setting by allowing an arbitrary number of blocs and expanding the set of possible deviations to include multi-country gradual deviations. We show that a Pareto optimal landscape equilibrium which is immune to profitable gradual deviations always exists. We also indicate that while a landscape equilibrium is a stronger concept than Nash equilibrium in pure strategies, it is weaker than strong Nash equilibrium.     

雾霾的经济学分析

中国不合理的能源消费结构、工业废气的大量排放、机械化程度的提高以及城镇化发展中建筑工地的大量扬尘是造成雾霾现象日趋严重的经济学原因。雾霾诱发了一系列社会经济负效应,必须采取积极的对策措施加以治理。     

辽宁省能源消费的长期均衡与短期波动研究

构建了辽宁省能源消费影响因素的VAR模型,并应用辽宁省1978—2010年间的时间序列数据进行了实证检验。结果表明,辽宁省能源消费与各类因素之间存在长期均衡的稳定关系,其中,重工业比重的变动对能源消费的长期影响最为显著,第三产业比重的调整对能源消费的短期波动具有显著影响。从脉冲响应函数和方差分解中都可以看出,人口因素对能源消费的扰动与其他因素相比是最不显著的。
