国外农业行业协会的成功经验

国外农业行业协会有两种模式：一是以美国为代表的“民管”模式。这种模式中政府只负责产业政策导向和市场环境建设，而不参与协会的组建、人员安排和经费的资助。协会工作体现出相当强的主动性和灵活性。美国联邦政府只从税收上进行管理，其他政府部门对行业协会等社团无管理权，只有资助或不资助的权利。二是以德国和日本为代表的“政社共管”模式。这些国家的行业协会分为“民办”和“官办”两种，但以民办为主。其特点是“双向”服务，即同时为农户和政府服务。政府的行业管理内容主要是：

城市森林在生态城市建设中的作用研究

随着世界经济的发展和城市人口的增加,城市环境问题严重阻碍了城市可持续发展。"生态城市"本质应是能量资源节用低耗再生创造、环境生态去污自净循环更新、城市的自然化生态与生态化的现代人居城市有机融合;而经济、社会、人文、地理、气候、环境、资源一定程度的和谐是生态城市构建的基础前提条件和良性反馈对象。构建"城市森林"是生态城市的实现路径,具有重大战略意义。     

生态城市建设的观念创新

Political culture and foreign direct investment: The case of Italy

Does the political culture of an area have any impact on the foreign direct investment (FDI) decisions of multinational corporations (MNCs)? This question is difficult to address empirically, as locations differ in many dimensions. We therefore address this question by examining MNC investment location decisions with regard to different regions within a single country. The country we examine is Italy, which exhibits one of the highest levels of variation with regard to the political culture of its geographical regions. We find that political culture as represented by the pattern of support for political parties at different points on the political spectrum has a significant impact on the MNC investment location decision. Thus, in choosing between locations on a short list, where economic and financial location factors are roughly similar, political culture can have a determining influence. In the case of Italy, a Center-right orientation is conducive to MNC FDI, while a Center-left orientation is not. A Far-left orientation is found to have a very negative effect on FDI.

Information acquisition,foreign bank entry,and credit allocation

This paper presents a theoretical framework to understand the impact of foreign bank entry on the access to and the price of credit for different types of firms. A major point of departure from the previous literature is that incumbents’ information about firms is endogenous in the model; previous screenings and lending relations of incumbents determine which type(s) of firms they can identify. I show that incumbents’ information is negatively correlated with the quality of borrowers. Moreover, although a priori entrants have a comparative advantage in lending to transparent firms, previous lending relations of incumbents might reverse this relation. In particular, given that transparent firms are the only type screened before the entry and therefore they are the only type distinguishable by incumbents, entrants might have a comparative advantage in lending to opaque firms. The analysis provides new insights into the inconclusive evidence of the literature regarding entrants’ credit allocation.     

促进中小企业发展的财税政策思考

改革开放以来,我国中小企业得到了快速发展,已成为拉动地方经济发展的重要力量。但是,自2008年的国际金融危机以来,中小企业发展遭遇到了前所未有的困难。为了使广大中小企业迅速摆脱危机的影响,本文提出要大力借鉴国外经验,不断完善政府对中小企业的支持体系建设;强化金融支持,缓解中小企业融资困难;加大税收优惠力度,大力扶持中小企业;实行推定课税,降低中小企业税收负担;推行特别财政政策等举措,使中小企业实现可持续发展。     

城市生态系统的评价在生态城市规划中的应用(英文)

本文通过两个实例来说明不同的城市生态系统评价方法在生态城市规划中的应用。在天津市生态足迹研究中,计算得知全市2003年人均生态足迹和生态承载力分别为2.12公顷/人和0.33公顷/人,生态赤字高达1.79公顷/人,因此在其生态城市建设规划中提出了相应的能源和生物资源高效利用措施;在石家庄市生态系统健康评价中,评价了其2001年～2005年的生态系统健康水平。结果表明,生态系统在2001年处于病态,在后4年内处于亚健康状态。规划中提出了使生态系统向着健康有利方向发展的对策建议。     

Developing foreign bank efficiency models for DEA grounded in finance theory

We develop foreign bank technical, cost and profit efficiency models for particular application with data envelopment analysis (DEA). Key motivations for the paper are (a) the often-observed practice of choosing inputs and outputs where the selection process is poorly explained and linkages to theory are unclear, and (b) foreign bank productivity analysis, which has been neglected in DEA banking literature. The main aim is to demonstrate a process grounded in finance and banking theories for developing bank efficiency models, which can bring comparability and direction to empirical productivity studies. We expect this paper to foster empirical bank productivity studies.     

Mixed oligopoly, foreign firms, and location choice

We investigate a mixed market in which a state-owned, welfare-maximizing public firm competes against n domestic private firms and m foreign private firms which are all profit-maximizing. A circular city model with quantity-setting competition is employed. We find that the equilibrium location pattern depends on m. All private firms agglomerate in the unique equilibrium if m is zero or one. Two foreign firms induce differentiation between domestic and foreign private firms. More than two foreign firms yield differentiation among the foreign firms. Regardless of n and m, agglomeration of all domestic private firms appears in equilibrium. We provide several conditions in which eliminating the public firm from the market enhances social welfare. We extend the basic model and investigate three issues concerning multiple public firms, inefficiency of the public firm, and entries by private firms. We obtain some additional implications of welfare and equilibrium locations.

Dynamics of quote and deal prices in the foreign exchange market

We empirically investigate price fluctuations of yen-dollar exchange rate using the high-frequency data recorded in the electronic broking system for seven-year period. The distribution of quote price changes has symmetric fat-tails approximated by a power law; however, that of deal price is asymmetrical. The autocorrelation function and diffusion of price changes indicate that quote price exhibits anti-correlation feature in short time scale, whereas deal price is essentially uncorrelated. The bid-ask spread shows power-law distribution and long range temporal correlations similar to that observed in absoute price changes.
