加快推进公共支出转型 增强江苏经济增长消费驱动力

投资和出口在江苏经济增长过程中扮演着特别重要角色,而消费对经济增长的驱动作用在持续下降。作为影响居民消费的重要因素,江苏的公共支出并未对城乡居民消费产生挤入效应。江苏公共支出转型总体上符合经济发展方式转变的要求,但也存在相关的问题。因此,应加快推进公共支出转型,增强江苏经济增长的消费驱动力。     

Emotions and dissonance in ‘ethical’ consumption choices

Abstract

This paper investigates the role of emotions and the prevalence of dissonant/incongruent choice behaviour within the context of ethical consumption. Based on 31 in-depth interviews with British consumers, the findings demonstrate that consumers consciously indulge in ‘ethical’ and ‘unethical’ behaviour (as defined by respondents themselves), often within short time frames, and that they often compensate for unethical choices by making ethical choices later on (and vice versa). The study provides evidence that positive and negative emotions are a key driver of this dissonant behaviour. Guilt is the most salient emotion, and a taxonomy of guilt in this context is derived from the data. Consumers are found to employ guilt-management strategies in order to sustain contradictory behaviour and manage cognitive dissonance. A conceptual framework is derived in order to summarise the observed role of emotions in ethical consumer choice. The paper also provides additional explanations of the manifestation of the attitude–behaviour gap.     

The role of customer values in accepting information technologies in the public information service sector

Many government agencies have outsourced their information systems to software vendors. Firms in the information service industry have to realize the needs of customers in the public sector. This study investigated the causal relationship between users' perception and information technology acceptance. Empirical results suggest that the perceived value of users plays an important and mediating role in the causal relationship among social influence process, cognitive instrumental process, and intention to use.     

Food insecurity,income inequality,and the changing comparative advantage in world agriculture

I would like to argue in this article that in the process of economic development in land‐poor countries in Asia, agriculture faces three distinctly different problems: food insecurity, sectoral income inequality, and the declining food self‐sufficiency associated with the declining comparative advantage in agriculture at the high‐income stage. Massive imports of food grains to Asia, if they occur, will aggravate the world food shortage, which will have significant implications for the poverty incidence in the world. I argue that in order to avoid such a tragedy, Asia should expand farm size to reduce labor cost by adopting large‐scale mechanization, sub‐Saharan Africa should realize a green revolution in grain production, and Latin America should further expand its grain production capacity.

木质林产品进口与中国木材市场消费及木材生产关系的实证研究

根据协整理论和格兰杰因果检验方法,对中国木质林产品进口和国内木材市场消费量及木材年产量之间的关系进行了实证研究。分析结果表明:中国木质林产品进口与木材消费量及年产量之间存在长期稳定的均衡关系,同时在滞后期为1的情况下木质林产品进口与木材市场消费量和木材年产量之间存在单向的格兰杰因果关系。据此,在分析国内木材供需的基础上,提出了大力发展人工林、提高木材利用率、优化进口市场结构等对策建议,以解决对进口木材依赖的问题。     

The sufficiency strategy: Would rich-world frugality lower environmental impact?

One alleged weapon against unsustainable environmental impact is for the wealthy to consume less. This sufficiency strategy is to complement the efficiency strategy of lowering ratios of resource inputs to economic outputs; the former would reduce the affluence factor in I = PAT, the latter the technology factor. That the latter strategy suffers from a consumption rebound is widely recognized. This paper identifies a similar rebound when the affluence factor is autonomously lowered: The lower initial demand lowers prices, which in turn stimulates new demand by others. The strategy moreover addresses only the rich, raising questions of its theoretical maximum efficacy. Its proponents usually conflate frugality with the North-South dichotomy and intragenerational with intergenerational equity. Moreover, there are difficulties with the supporting arguments that frugality is good for one’s own sake as well as for the environment, and that the rich should ‘lead the way’ to living more lightly. Personal behaviour change is furthermore not a substitute for international political efforts. Finally, since all changes in right-side factors of the I = PAT equation change other right-side factors, such indirect attacks on impact should be abandoned in favor of supply and emissions quotas.     

Modeling population dynamics and economic growth as competing species: An application to CO2 global emissions

Since the beginning of the last century the world is experiencing an important demographic transition, which will probably impact on economic growth. Many demographers and social scientists are trying to understand the key drivers of such transition as well as its profound implications. A correct understanding will help to predict other important trends of the world primary energy demand and the carbon emission to the atmosphere, which may be leading to an important climate change. This paper proposes a set of coupled differential equations to describe the changes of population, gross domestic product, primary energy consumption and carbon emissions, modeled as competing species as in Lotka-Volterra prey-predator relations. The predator-prey model is well known in the biological, ecological and environmental literature and has also been applied successfully in other fields. This model proposes a new and simple conceptual explanation of the interactions and feedbacks among the principal driving forces leading to the present transition. The estimated results for the temporal evolution of world population, gross domestic product, primary energy consumption and carbon emissions are calculated from year 1850 to year 2150. The calculated scenarios are in good agreement with common world data and projections for the next 100 years.     

Measuring resource inequalities: The concepts and methodology for an area-based Gini coefficient

Although inequalities in income and expenditure are relatively well researched, comparatively little attention has been paid, to date, to inequalities in resource use. This is clearly a shortcoming when it comes to developing informed policies for sustainable consumption and social justice. This paper describes an indicator of inequality in resource use called the AR-Gini. The AR-Gini is an area-based measure of resource inequality that estimates inequalities between neighbourhoods with regard to the consumption of specific consumer goods. It is also capable of estimating inequalities in the emissions resulting from resource use, such as carbon dioxide emissions from energy use, and solid waste arisings from material resource use. The indicator is designed to be used as a basis for broadening the discussion concerning ‘food deserts’ to inequalities in other types of resource use. By estimating the AR-Gini for a wide range of goods and services we aim to enhance our understanding of resource inequalities and their drivers, identify which resources have highest inequalities, and to explore trends in inequalities. The paper describes the concepts underlying the construction of the AR-Gini and its methodology. Its use is illustrated by pilot applications (specifically, men's and boys' clothing, carpets, refrigerators/freezers and clothes washer/driers). The results illustrate that different levels of inequality are associated with different commodities. The paper concludes with a brief discussion of some possible policy implications of the AR-Gini.     

持久性收入对中国农民消费影响分析

运用弗里德曼的持久性收入假说分析我国农民的消费问题,并利用计量经济学的方法对中国历年农民消费统计数据进行分析,得出“持久性收入及持久性收入的边际消费倾向对我国现阶段农民消费支出影响较大”的结论,并从增加持久性收入和提高持久性收入的边际消费倾向两个方面就增加农民消费提出政策建议。
