基于生态学思考的小城镇新区规划设计新理念

基于生态学的思考,小城镇新区规划设计应树立五个新理念:深化人本思想、突出文化内涵、注重景观设计、树立超前意识、发扬务实精神。新理念在实践过程中体现在:营造人性化的小城镇新区、塑造地方性的小城镇特色、打造园林式的小城镇景观、构造灵活性的小城镇格局、绘就实用性的小城镇蓝图。     

休闲观光农业经营管理方案研究

休闲观光农业是一种利用田园景观、自然环境、生态资源，结合农林渔牧业生产、农村文化及农家生活，在不耽误农业生产的基础上又为城市居民提供休闲体验活动的农业经营模式。休闲观光农业能够利用当地丰富的农业资源、旅游资源和劳动力资源实现当地农业可持续发展。但它的发，晨过程也可能带来很多负面影响。这就要求我们在设计休闲观光农业的经营方案时要根据农业与旅游这两个行业的特点。通过各自的经营管理要素对其分别进行比较分析，找到了两个行业的异同，并采用经营管理构建方法。逐步导出休闲观光农业的经营方案。     

城乡关系协调视角下的中国乡村工业化

实现乡村新型工业化是中国城乡区域实现良性互动及促进城乡和谐发展格局的关键途径与基本动力。在城乡关系协调的过程中推进乡村工业化，必须重视乡镇企业在新时期的转型与发展，创新农业产业化经营与运作模式，不断培育壮大农业企业家的人力资本支撑，最终实现城乡协调互动基础上的共同繁荣与进步。     

地区专业化、产业集中与经济集聚——对我国制造业的实证分析

以新经济地理学模型为基本理论框架,对我国各省区专业化水平、制造业各行业的集中程度和整个制造业的集聚程度进行了实证分析,结果显示1993—2003年间我国各省份的专业化水平呈显著上升趋势,制造业大部分行业集中程度提高,整个制造业集聚程度上升。在制造业各行业集中程度和整个制造业集聚程度的测算中,引入SP指数,结果显示这一指标的引进是非常必要的。     

The optimal portfolio for the two-pillar mandatory pension system: the case of Poland

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying.

The Economics and Bioeconomics of Folk and Scientific Classification

Synopsis This paper is the product of a collaboration between a biologist (Ghiselin 1997) who works on the philosophy of classification and an economist (Landa 1981, 1994) who works on the ‘Economics of Identity’: how and why people classify people based on identity in the context of a theory of ethnic trading networks. In developing the ‘bioeconomics’ (the synthesis of economics with biology) of classification, we crossed a number of disciplinary boundaries—anthropology, economics, sociology, biology, and cognitive psychology including evolutionary psychology’s ‘fast and frugal’ heuristics. Using a bioeconomics approach, we argue that folk classifications—the classifications used by ordinary persons—have much in common with scientific classifications: underlying both is the need for economy of information processing in the brain, for the efficient organization of knowledge, and for efficiency of information acquisition and transmission of information to others. Both evolve as a result of trial and error, but in science there is relatively more foresight, understanding, and planning.
