同机器生产力相比较,网络生产力不仅在理论上是一个崭新的经济学范畴,而且在实践层上,从其内部的基础结构以及同社会经济运行联系两方面,都呈现出鲜明的特征;网络生产力既具极强的经济定义,又具极强的经济学意义。  相似文献

The mineral investment decision under certainty is discussed in the context of broad microeconomic features of the industry, the central one being that production is constrained by capacity. The assumptions of the economic literature on natural resources are evaluated in the context of these features and the assumptions that permit the modeling of such facts are examined. Several characteristics of extraction and equilibrium, and some implications of uncertainty, are considered.  相似文献

Local economic development policies have surged in Brazil over the past decade—a major shift in this regionally diverse country of 27 states, over 5000 municipalities, and the largest economy in Latin America. We review the stylized facts, expected patterns and policy recommendations from the foundational studies in regional and urban economics. We then provide a summary of a more recent stream of scholarship focused on local economic development (LED) studies in developed and developing countries that have surged in the last 20 years. Based on this review, we then systemize the findings emerging from studies focused on analyzing local economic development policies in Brazil recognizing the distinctive contributions emerging from both the empirical and the case studies literatures. We identify key lessons for (and from) the Brazilian experience and conclude that Brazil and Latin American countries need a new generation of studies that undertake more rigorous evaluations of these policy experiments. Finally, we recommend steps to advance such research.  相似文献

人口总量及其空间分布特征与经济发展关系的动力学研究   总被引:5,自引:3,他引:2  
陈楠  林宗坚 《测绘科学》2006,31(4):14-16
建立了人口—经济系统的微分方程组模型,并在方程中引入人口空间分布与经济发展协调的因子η,通过分析模型的稳定性特征得出以下结论:人口经济系统是复杂的非线性关系;人口的过于快速增长会使经济总量趋向于零;如果η>1并且较高,则人口经济系统发展稳定时,经济总量会高些,也即人口数量稳定在同样水平时,会因为空间分布的不同而有不同的经济产出。说明在控制人口数量的同时必须重视人口空间分布的问题。  相似文献

Even if a global agreement is achieved on climate change issues, it is likely that national policies will continue to differ. Consequently, the competitiveness of some industries could be affected and the so-called ‘carbon leakage’ effect might occur. This effect is more likely for those industries with a risk of relocation. Most of the studies that examine the carbon leakage phenomenon look at implications at the national or supra-national level, and neglect the important fact that some of the key industries affected are highly concentrated in the old industrial regions (OIRs). From a regional perspective, it is clear that these areas are affected more severely by climate policies. Using a computable general equilibrium (CGE) model, the impacts for one of the most vulnerable sectors – the iron and steel (IS) sector in the European OIR of the Basque Country (BC) – are first examined. The analysis is then replicated for the OIR of the North RhineWestphalia (NRW) region in Germany. The results show that although total effects may be diluted from a national perspective, the economic impact at the regional level may be quite large and may significantly reduce regional gross domestic product (GDP). This has broader implications for the OIRs and suggests a need to further explore policy insights for economic development and adaptation in them.  相似文献

This paper reports an empirical analysis of the distribution of employment by industry in Melbourne and how this changes over time. Depending on the nature of the industry being considered, two main patterns of spatial behavior are found, population-related dispersion and centralization. A methodology for estimating the benefits of centralization is developed and applied. Centralization benefits are highest for business services and other high-level services, supporting the view that the benefits of concentrating in the central business district are related to knowledge creation and exchange. Other forces, such as competitive pressure, land prices, and colocation with other industries, play only a minor role in determining the spatial distribution of industries, at least at the spatial levels used here. The implications of these findings are discussed.  相似文献

气象具有三重经济学属性:一是生产力属性,它既是创造自然财富的自然生产力,又是创造人工财富的社会生产力。二是气象的破坏力属性,即是天气和气候的状态所致的具有经济特征的多发气象灾害。三是气象的消费属性,即人们的生产与生活中,不可须臾离却气象。认识气象的经济学属性,有利于充分利用和发挥好气象的资源价值,创造更多的社会财富;有利于降低灾害性气候的破坏影响,提高人类社会福祉。  相似文献
