走出“中国制造”的困惑

全球制造业出现了由发达国家向发展中国家转移的趋势,中国制造业可以凭借劳动力资源丰富的优势加速发展。但是目前“中国制造”是以低价格、低成本优势进入了国际市场,参与国际分工,从长远的观点看,不利于中国经济的可持续发展。因此,“中国制造”要摆脱困境,在作好委托生产的同时,要打造自己的品牌,提升“中国制造”的档次。     

Determinants of residential water demand in Germany

We econometrically analyze the impact of several economic, environmental and social determinants for the per capita demand for water in about 600 water supply areas in Germany. Besides prices, income and household size, we consider the effects of population age, the share of wells, housing patterns, precipitation and temperature. We also explore why current per capita residential water consumption in the new federal states is about 30% lower than in the old federal states. Since average cost pricing may cause an endogeneity problem, we apply instrumental-variable procedures in addition to single equation ordinary least squares, but find no evidence that prices are endogenous. Our estimation results suggest that the price elasticity of water demand in Germany is around − 0.24. The income elasticity is positive, decreases with higher income levels and is at least three times higher in the new federal states than in the old federal states. Current differences in prices and income levels explain about one third of the gap in residential water use between the two regions. Household size and the share of wells have a negative impact on per capita water demand, and water use increases with age. Finally, the findings provide some evidence that rainfall patterns rather than total rainfall affect water consumption, while temperature appears to have no impact at all. All outcomes are robust to a log-log and two types of semi-log specifications for the water demand function.     

品牌经济学的理论基础——引入品牌的需求曲线及其经济学分析

需求定律是经济学分析的理论基础之一,品牌经济学的理论基础为引入品牌的需求曲线或考虑选择成本的需求定律。把品牌引入经济学中后,品牌信用度的提高使需求曲线右移并变得更为陡峭,同时品牌信用度的提高改变了需求曲线的位置,使得均衡价格提高,均衡数量增加,增加了消费者剩余和生产者剩余,提高了社会福利水平。文章为“品牌战”替代“价格战”提供了理论依据,即通过品牌建设提高品牌信用度,使得在价格提高的条件下需求量增加,而这只有在需求曲线改变位置时方能做到。     

A review of experience curve analyses for energy demand technologies

Transitioning towards a sustainable energy system requires the large-scale introduction of novel energy demand and supply technologies. Such novel technologies are often expensive at the point of their market introduction but eventually become cheaper due to technological learning. In order to quantify potentials for price and cost decline, the experience curve approach has been extensively applied to renewable and non-renewable energy supply technologies. However, its application to energy demand technologies is far less frequent. Here, we provide the first comprehensive review of experience curve analyses for energy demand technologies. We find a widespread trend towards declining prices and costs at an average learning rate of 18 ± 9%. This finding is consistent with the results for energy supply technologies and for manufacturing in general. Learning rates for individual energy demand technologies are symmetrically distributed around the arithmetic mean of the data sample. Absolute variation of learning rates within individual technology clusters of 7 ± 4%-points and between technology clusters of 7 ± 5%-points both contribute to the overall variability of learning rates. Our results show that technological learning is as important for energy demand technologies as it is for energy supply technologies. Applying the experience curve approach to forecast technology costs involves, however, unresolved uncertainties, as we demonstrate in a case study for the micro-cogeneration technology.     

中国经济体制改革时期制度变迁的特征分析

从实质上说，中国经济体制改革的过程就是一个制度的重建过程，即以适应市场经济的制度安排取代适应计划经济的制度安排取代适应计划经济的制度安排的过程。在这一制度重建的进程中，市场取向的制度变迁表现出八个方面的典型特征：一是制度变迁需求的内性性；二是制度变迁供给的滞后性；三是制度变迁目标的动态性；四是制度变迁过程的渐进性；五是制度变迁轨迹的路径依赖性；六是从单项制度变迁向制度结构变迁演进；七是强制性制度变迁与诱致性制度变迁相结合；八是宏观经济制度变迁与微观经济制度变迁同步进行。     

关于中国劳动者权利实现因素的分析——以企业劳动关系为视角

企业劳动关系状况受众多因素影响,目前,中国劳动力市场供求矛盾尖锐,企业在全球网络化生产组织中的地位较低,劳动法律体系不完善是造成企业劳动关系紧张的主要因素。     

基于不对称需求信息的激励机制模型研究

针对由单制造商和单销售商组成的供应链,提出了供应链双方需求信息对称情况下的激励机制模型,并在此基础上建立了供应链双方在需求信息不对称情况下的运作策略模型。制造商通过折扣,运用激励相容机制使销售商诚实申报需求信息,使得供应链利润最大化的同时供应链成员实现双赢。数字试验结果表明:①所提策略是有效的;②该策略不仅能提高制造商利润,而且也能改善销售商的利润。     

Competition and physician-enabled demand: The role of managed care

Recent organizational changes in the health care sector promote greater patient participation in their treatment decisions. How physicians respond to patient-initiated requests for treatment is an issue of considerable policy interest. To study this phenomenon, we introduce the notion of physician-enabled demand and examine empirically whether this behavior responds to competitive pressures in the market and financial incentives associated with different physician payment mechanisms.We find that physician-enabled demand increases with more competition under fee-for-service reimbursement, but decreases with greater competition under managed care. This asymmetric response is quite consistent with our conceptual framework and at odds with alternative interpretations.     

新疆劳动参与率偏低的原因分析

本文通过对新疆和全国劳动参与率的比较分析,得出新疆地区的劳动参与率明显低于全国水平,并对此产生的原因作了简要分析。除了各种宏观经济因素外,与新疆地区推行特殊的少数民族生育政策而带来的高幼儿扶养比和该地区传统的小富则安缺乏竞争意识的思想观念也有很大关系。     

天津财政教育支出结构分析

对1996年以来天津公共教育支出结构进行了实证分析,指出天津公共教育支出存在着基础教育领域投资力度弱、义务教育阶段教育资金使用不合理、政府间教育支出分担不够合理等三方面结构不合理问题,在此基础上进一步提出相应的调整策略。
