长江三角洲区域政策强度的定量化及其演变过程——以区域开放开发政策为例

区域政策强度是政府投入影响区域经济格局的政策变量值的大小。区域政策强度的影响因素可分为政策自身内容和政策背景属性两类,前者主要考察政策工具体系,后者则主要考察区域政策的影响范围和政策实施保障能力。在此基础上提出区域政策强度定量化的指标体系,据此定量考察区域政策强度值的时空演变规律与特征。以改革开放以来长江三角洲实施的区域开放开发政策作为实证研究样本,经过区域政策强度的定量化分析发现:区域开放开发政策强度具有能级上的差异,不同类型区域政策的强度值变化特征不同,并在时间上呈阶段性和周期性,在空间上由等级梯度向扁平化转变。     

THE SPATIOTEMPORAL EVOLUTION OF U.S. CARBON DIOXIDE EMISSIONS: STYLIZED FACTS AND IMPLICATIONS FOR CLIMATE POLICY

We characterize the evolution of U.S. carbon dioxide (CO₂) emissions using an index number decomposition technique which partitions the 1963–2008 growth of states’ energy‐related CO₂ into changes in five driving factors: the emission intensity of energy use, the energy intensity of economic activity, the composition of states’ output, per capita income and population. Compositional change and declining energy intensity attenuate emissions growth, but their impacts are offset by increasing population and income. Despite absolute interstate divergence in both emissions and their precursors, states’ emission‐ and energy intensities—and ultimately, CO₂—appear to be stochastically converging. We assess the implications of these trends using a novel vector autoregression (VAR) emission forecasting technique based on our index numbers. The resulting emission projections are comparable to, but generally exceed, those forecast by the 2010 EIA Annual Energy Outlook.
