我国引进技术消化吸收与青少年成长教育类比分析及建议

消化吸收是我国技术引进后实现良性循环的重要环节,但目前一直存在效果不佳的问题。为了充分发挥技术引进的后发优势,通过应用相似系统理论,从我国青少年成长过程期间可能遇到的问题及预防措施来类比我国技术引进消化吸收工作中存在的不足,并给出相应的建议措施。     

新农村建设:一个政治经济学视角的解析

新农村建设是对城乡经济社会发展不平衡的一个积极回应,它包含经济增长和社会发展两个层面.从政治经济学视角出发,在经济增长方面,户籍、土地、保障等制度性因素制约到农村劳动力的有效流转,从而对劳动生产率提升和农业发展产生负面影响;在社会福利方面,农民的数量优势没有转化为谈判优势,对市场价格和政策制定的影响力较小,其社会福利获取以及发展程度处于不利地位.据此,新农村建设必须对相关制度性、组织性因素进行完善和改革,部分农民的真正流转和留守农民的自发组织将尤其重要.     

生态经济理论与经济体制改革

经济体制改革的理论基础不仅仅是社会主义市场经济理论,生态经济理论也是其中之一,这是由生态经济理论原则及特点所决定了的。同时,改革的目标是建立社会主义市场经济体制,在新体制的建立过程中,也必须注意实现生态经济协调的几个问题。     

Indigenous livelihoods, slash-and-burn agriculture, and carbon stocks in Eastern Panama

Improved crop–fallow systems in the humid tropics can simultaneously sequester atmospheric carbon emissions and contribute to sustainable livelihoods of rural populations. A study with an indigenous community in eastern Panama revealed a considerable biophysical potential for carbon offsets in small-scale slash-and-burn agriculture through longer fallow periods, improved fallow management, secondary forest development, and agricultural intensification. Based on soil and biomass carbon measurements, estimated annual sequestration rates amount to 0.3−3.7 t C ha^− 1 yr^− 1. Despite such potential, the economic benefits of initiatives aimed at sequestration of carbon in the community are likely to be rather unequally distributed within the community. Heterogeneity in livelihood strategies and uneven asset endowments among households – factors often overlooked in the ongoing carbon and sustainable development debate – are expected to strongly affect household participation. Indeed, only the better-endowed households that have also managed to diversify into more lucrative farm and non-farm activities are likely to be able to participate in and thus benefit from improved crop–fallow systems that capture carbon. Economic, ethical, institutional, and technical concerns need to be taken into account when designing community carbon management and investment plans.

Affection not affliction: The role of emotions in information systems and organizational change

Most IS research in both the technical/rational and socio-technical traditions ignores or marginalizes the emotionally charged behaviours through which individuals engage in, and cope with the consequences of, IS practice and associated organizational change. Even within the small body of work that engages with emotions through particular conceptual efforts, affections are often conceived as a phenomenon to be eradicated – an affliction requiring a cure. In this paper, I argue that emotions are always implicated in our lived experiences, crucially influencing how we come to our beliefs about what is good or bad, right or wrong. I draw from the theoretical work of Michel Foucault to argue for elaborating current notions of IS innovation as a moral and political struggle in which individuals’ beliefs and feelings are constantly tested. Finally, I demonstrate these ideas by reference to a case study that had considerable emotional impact, and highlight the implications for future work.     

Fiscal federalism in rentier regions: Evidence from Russia

When does sub-national fiscal autonomy prompt regional growth and recovery and, under what conditions, does it have adverse effects? We argue that unearned income streams, particularly in the form of revenues from natural resource production or from budgetary transfers from the central government, transform regions dependent on these income sources into rentier regions. Governments in these regions can use local control over revenues and expenditures to shelter certain firms, i.e., natural resource producers or loss-making enterprises, from market forces. Using fiscal data from 80 Russian regions from 1996 to 1999, we test this hypothesis in both cross-sectional and panel specifications. Our results indicate that tax retention, which is a proxy for fiscal autonomy, has had a positive effect on regional reform and investment since the break-up of the Soviet Union. However, we also find that this effect decreases as rentable income streams to regions increase. Journal of Comparative Economics 33 (4) (2005) 814–834.     

Two–step sequential sampling

Choosing the sample size in advance is a familiar problem: often, additional observations appear to be desirable. The final sample size then becomes a random variable, which has rather serious consequences.
Two such sample extension situations will be considered here. In the first situation, the observed sample variance determines whether or not to double the original sample size. In the second situation, the variances observed in two independent samples are compared; their ratio determines the number of additional observations.     

Testing separability of public consumption in household decisions

In this paper we propose a sequential strategy, based on the microeconomic approach of the demand theory, in order to test for separability between private and public consumption. The aim of the present work is to verify, using a conditional almost ideal demand system, whether the different components of public consumption exert conditioning effects on the allocative structure of private spending. The empirical estimation of the model and the separability tests are developed for both a demand system in five functional categories of private spending, and for a demand system in six categories, where the private expenditures on those goods and services which can also be offered by the public sector are enclosed in a single functional category. The results of the separability tests, obtained using UK data for the 1974–2000 period, show that public individual consumption plays an important role in modifying consumer choices, while public collective consumption does not affect private consumption behaviours. The relationships between the different components of private spending and public individual consumption are both of substitutability and complementarity; in particular, we find that public individual consumption and the corresponding private expenditures on ‘Health, education, recreation and social protection’ are complements.     

Inter-basin water transfers under uncertainty: Storage capacity and optimal guaranteed deliveries

This paper deals with water transfers between jurisdictions not claiming riparian rights to the same water source, and taking place through straightforward sales. Taking into account the uncertain nature of water surpluses, we investigate, within a partial equilibrium framework, the implications of a third party's provision of storing facilities upon the potential supplier's decision whether, and to what extent, it is worthwhile to guarantee a constant amount of water exports. The analysis suggests that there exists a minimum storage capacity below which the potential supplier will never find it profitable to divert a constant amount of water outside his boundaries; the greater the uncertainty about future surpluses and/or internal costs due to even occasional water shortages resulting from the water export commitment, the higher the required minimum storage capacity will be. Above this minimum, an increase in the capacity would be better for the surplus agent, but in a situation in which water surplus is expected to decrease over time, increases in storage capacity would make him willing to guarantee a smaller amount of water deliveries.This work has been carried out under the auspices of the European Science Foundation's research program Sharing fresh water resources in the Mediterranean region: An economic perspective.
