黑龙江省典型城市合理用地规模确定的实证研究——以大庆市为例 总被引:1,自引:0,他引:1
以黑龙江省典型的资源型城市——大庆市建成区为研究对象,用1990—2004年的数据建立经济数学模型。利用Excel软件分析了城市用地规模与经济发展水平之间的关系,表明两者呈相互关联的非线性变化规律。假定在同一技术条件下,采取成本—效益模型计算出确保城市经济效益最优时的土地面积即为合理用地规模,通过计算城市空间扩展度,得出现有城市用地规模大于合理用地规模的结论,在今后的经济发展中应考虑适当地控制城市用地规模。 相似文献

基于灰色系统模型的城乡建设用地规模预测——以常德市鼎城区为例 总被引:6,自引:0,他引:6
土地利用总体规划是区域性的综合规划,为地方性的经济发展提供科学和法律依据.建设用地的有效供给是地方经济发展基础,建设用地需求量预测是土地利用总体规划编制的核心,也是土地利用管理的依据.为了切实搞好常德市鼎城区的土地利用总体规划,使之更具有前瞻性、可操作性,必须切合实际地搞好建设用地需求规模和布局的预测.采用灰色系统模型,通过灰色关联度分析,建设用地发展与GDP、总人口、市镇人口、社会固定资产投资、人均GDP、第二产业产值、第三产业产值密切相关.基于这些因子,采用灰色系统模型法、建立GM(1,1)灰色模型,进行了2010年和2020年的城乡建设用地规模的预测.GM(1,1)模型可以进行长期预测,但预测仅反映一种趋势,综合考虑驱动因素的灰色线性组合模型更具有预测的可靠性.利用GM(1,1)模型和线性模型组合,进行城乡建设用地规模预测,可为土地利用总体规划提供可靠的保证. 相似文献

ABSTRACT The argument over the effects of financial structures on economic growth remains unsettled. This study, therefore, compares the dynamic correlation and lead–lag relationship between the different financial approaches within the banking sector (that is, traditional bank loans versus innovative financial leasing) and economic growth. We employ a continuous wavelet analysis using time-series data from 1982–2017 from the US (the world’s largest developed country) and China (the world’s largest developing country). The empirical results show that (1) episodes of significant correlation usually emerge during periods of reform, crisis or policy implementation; and (2) in China, traditional banking promotes economic growth in the long term, while the real economy only imputes the evolution of banks during critical economic reforms in the short term. Meanwhile, financial leasing could only promote the development of the real economy under suitable regulation; and (3) in the US, before the crises, the irrational growth of the real economy could increase bank assets, while during the crises, the traditional banking approach harms economic growth, and after the crises, financial leases play an important role in recovery. Therefore, we suggest that policymakers should establish adequate policies and regulations to solve the situation. 相似文献

Productivity Growth, Efficiency and Outsourcing in Manufacturing and Service Industries 总被引:8,自引:1,他引:8
Almas Heshmati 《Journal of economic surveys》2003,17(1):79-112
This paper is a survey of recent contributions to, and developments of, the relationship between outsourcing, efficiency and productivity growth in manufacturing and services. The objective is to provide a thorough and up–to–date survey that provides a significant discussion on data, as well as on the core methods of measuring efficiency and productivity. First, the readers are introduced to the measurement of partial and total factor productivity growth. Different parametric and non–parametric approaches to the productivity measurement in the context of static, dynamic and firm–specific modelling are discussed. Second, we survey the econometric approach to efficiency analysis. The issues of modelling, distributional assumptions and estimation methods are discussed assuming that cross–sectional or panel data are available. Third, the relationship between outsourcing and productivity growth in manufacturing and services is discussed. The correspondence between a number of hypotheses and empirical findings are examined. Examples of varieties of relevant empirical applications, their findings and implications are presented. Fourth, measurement of inputs and outputs in manufacturing and services are discussed. Finally, to promote useful research, a number of factors important to the analysis of outsourcing, efficiency and productivity growth in the service sector are summarised. 相似文献

Summary. We seek to explain the economic volatility of the last 6 years, in particular the rapid expansion and contraction of the knowledge sectors. Our hypothesis is that these sectors amplify the business cycle due to their increasing returns to scale, growing faster than others in an upswing and contracting faster in a downswing. To test this hypothesis we postulate a general equilibrium model with two sectors: one with increasing returns that are external to the firm and endogenously determined - the knowledge sector - and the other with constant returns to scale. We introduce a new measure of volatility of output, a real beta, and derive a resolving equation, from which we prove that the increasing return sectors exhibit more volatility then other sectors. We validate the main results on US macro economic data of real GDP by industry (2-3 digits SIC codes) of the 1977-2001 period, and provide policy conclusions.Received: 18 March 2002, Revised: 16 February 2004, JEL Classification Numbers:

2005年起,我国开始实行稳健的财政政策,经济运行方式发生了变化,国债政策作为以前积极财政政策调节经济方向的重要工具也应采取相应变化以促进经济向前发展.由此加强我国国债规模管理,不仅应从总体上缩小国债规模,更应该注重国债资金的使用效率,对其加强监督管理. 相似文献
