控制火电厂二氧化硫排放的有效途径——排污权交易

目前,我国工业二氧化硫排放量中有42%是火电厂排放的,因此高效控制火电厂的二氧化硫排放是提高空气质量的主要途径。美国利用排污权交易治理火电厂的二氧化硫排放取得了巨大的成功,不仅二氧化硫排放量大幅下降,而且排污权交易也被证明是成本最低的方法。借鉴美国的经验,可以为我国治理火电厂二氧化硫排放提供高效途径。     

基于BP神经网络的我国M2/GDP预测与对策

本文计算了1993年至2005年我国M2/GDP,发现该数据总体呈上升趋势,这一定程度上反映了我国体制上的深层次问题。另外,本文运用带有动量项和自适应学习率的BP神经网络方法预测出我国2006年的M2/GDP是1.6386左右,并提出了一些相应的政策建议。     

大城市周边城乡融合区人口的就地城镇化——以福州市为例

城乡界限趋于模糊是20世纪后半叶以来亚洲许多国家城镇化进程的一个重要特点,大城市周边城乡融合区的形成和发展及其人口的就地城镇化即是这一特点的一个突出表现。以就地城镇化发达的闽东南地区的福州市为例,从实体地域和未来人口规模两方面探讨其城乡融合区的现状特点和发展趋势。在制定大城市的发展规划时,要密切关注其周边城乡融合区内农村人口就地转变为城镇人口、城市核心区人口向城乡融合区转移的状况,并在制定城市规划时把城乡融合区的发展趋势考虑进去。     

Regional and State Variation in Homeownership Rates; or If California's Home Prices Were as Low as Pennsylvania's Would its Ownership Rate be as High?

There are significant disparities in homeownership rates across the regions and states of the United States. The causes of these disparities are determined within a standard probit model of the individual homeownership decision where the micro-level observations are aggregated to the regional level. Factors which play a significant role at the individual level are evaluated for their ability to explain regional differentiation. The relative price of owning and renting plays a major role as do other market level determinants. Individual demographic characteristics are not as important with the exception of those related to the immigration and citizenship status of the household head.     

我国的M1/M2(1978-2002):长期趋势、水平与周期波动

本对我国1978—2002年的M1／M2的长期趋势、水平和周期波动进行了研究，结果表明1978—1995年，中国的M1／M2呈急剧下降的态势，但是从1996至今则基本保持平稳。另外从国别比较来看，我国属于M1／M2比较高的国家(地区)之一，这表明我国的居民和企业由于支付制度、取款成本、规避税收等原因比美、日等国家的经济主体对M1的需求高很多。除开长期走势之外，中国的M1／M2还伴随着经济活动呈周期性的波动，实证分析结果表明1996年前的经济增长率是M1／M2周期波动的Granger原因，但1996年以后则必须由名义利率、通货膨胀率和股票市场交易量的变动才能说明M1／M2的波动。     

维生素C二步发酵中优良菌株201A的研究

Industrial distributors: Can they survive in the new economy?

As e-commerce evolves and gains power in the business-to-business (B2B) marketplace, what lies ahead for the industrial distributor? The fundamental issue from the distributor's point of view is how to compete more effectively and profitably, given the changing business environment of the new economy. This paper reviews the literature on the distributor's role and relationships and introduces a conceptual model of distributor viability. The model identifies sources of value that distributors offer to manufacturers and customers, including customer relationship management (CRM), production and operations management (POM), and knowledge management (KM). The paper explores the managerial implications of distributor relationships and sources of value. This provides the foundation for better understanding of the viability of industrial distributors in the new economy.     

Back on the balance sheet: The tax effects of contingent claims in commercial banking

Contingent claims separate revenue and cost into two different time periods. Revenue comes in the initial origination process, while the cost comes upon completion of the contract in the event of default. With banks increasing contingent claims in recent years, a higher taxable income leads to a shift in a bank's balance sheet toward tax-free income and tax-shielding liabilities. This provides a valuable case-study of corporate finance theories of tax management. This paper builds a model to illustrate the income features of contingent claims. Call Reports from 1990-1996 are examined, and show significant evidence of increases in leverage associated with contingent claims.     

产业集群、区域经济与金融深化——金融支持中国戴南产业集群发展模式研究

积极实施城市反哺农村，工业反哺农业，以工业化致富农民，城市化带动农村，产业化提升农业，是建设社会主义新农村的成功经验。金融作为现代经济的核心，是支持社会主义新农村建设不可或缺的重要因素。本文结合中国戴南产业集群发展的轨迹，剖析了戴南产业集群发展的现状、特点以及制约集群进一步发展的金融瓶颈，提出了金融支持戴南产业集群发展的构想，着重指出了转变观念、创新机制、组合产品、完善体系等四个方面金融支持的新路径，为金融助推产业集群在经济欠发达地区的率先发展，提供了重要的实践模式。     

Estimating the Euler equation for output

New Keynesian macroeconomic models have generally emphasized that expectations of future output are a key factor in determining current output. The theoretical motivation for such forward-looking behavior relies on a straightforward generalization of the well-known Euler equation for consumption. In this paper, we use maximum likelihood and generalized method of moments (GMM) methods to explore the empirical importance of output expectations. We find little evidence that rational expectations of future output help determine current output, especially after taking into account the small-sample bias in GMM.
