Study of spatial patterns and spatial effects of energy eco-efficiency in China

Journal of Geographical Sciences 2016年第9期26卷 1362-1376页

作者： GUAN Wei XU Shuting Center for Studies of Marine Economy and Sustainable Development Liaoning Normal University Dalian 116029 Liaoning China Collegeof Urbanand Environment Science Liaoning Normal University Dalian 116029 Liaoning China

Energy eco-efficiency is a concept integrating ecological and economic benefits arising from energy utilization and serves as a measure of efficiency in the energy-environment-economy system. Using the slacks-based measure （SBM） model considering undesirable output, this study first measures the energy eco-efficiency of provinces in China from 1997 to 2012. It then analyzes the spatial distribution and evolution of energy eco-efficiency from three aspects： scale, intensity, and grain of spatial patterns. Finally, it examines the spatial spillover effects and influencing factors of energy eco-efficiency in different provinces by means of a spatial econometric model. The following conclusions are drawn：（1） The overall energy ecofficiency is relatively low in China, with energy-inefficient regions accounting for about 40%. Guangdong, Hainan and Fujian provinces enjoy the highest energy eco-efficiency, while Ningxia, Gansu, Qinghai, and Xinjiang are repre- sentative regions with low efficiency. Thus, the pattern of evolution of China＇s overall energy eco-efficiency is U-shaped. Among local regions, four main patterns of evolution are found： increasing, fluctuating, mutating, and leveling. （2） At the provincial level, China＇s energy eco-efficiency features significant spatial agglomeration both globally and locally. High-high agglomeration occurs mainly in the eastern and southern coastal regions and low-low agglomeration in the northwestern region and the middle reaches of the Yellow River. Changes in spatial patterns have occurred mainly in areas with high-low and low-high agglomeration, with the most remarkable change taking place in the Beijing-Tianjin-Hebei region. （3） There exist significant spatial effects of energy eco-efficiency among provinces in China. For the energy eco-efficiency of a given region spatial spillovers from adjacent regions outweigh the influence of errors in adjacent regions. Industrial structure has the greatest influence on energy eco-effic

Has Transport Infrastructure Promoted Regional Economic Growth?——With an Analysis of the spatial Spillover Effects of Transport Infrastructure

引用

Social Sciences in China 2013年第2期34卷 24-47页

作者：张学良 Lin Hong Institute of Finance and Economics Shanghai University of Finance and Economicsy

Taking full account of the synergistic effects of multidimensional factors on regional economic growth in China, this paper constructs a model of the spatial spillover effects of transport infrastructure on regional economic growth. Using provincial panel data from 1993 to 2009 and employing spatial econometric techniques, our empirical analysis comes to the following conclusions. （1） The total output elasticity of transport infrastructure for regional economic growth varies between 0.05 and 0.07, indicating its important role in such growth. （2） Transport infrastructure has very clear spatial spillover effects on regional economic growth; its role in regional economic growth will be overestimated if these are neglected. （3） For a specific region, transport infrastructure in other regions has mainly positive spillover effects on economic growth, but there is also evidence of negative spillover effects. （4） Among multidimensional factors contributing to regional economic growth, labor pluscapital stock from other parts of the public sector make the greatest contribution to regional economic growth in China, followed by the new economic growth factors and new economic geography.

依据中国282个城市2006～2018年政府引导基金、风险投资、发明专利以及城市经济的相关数据进行匹配，运用空间杜宾模型（SDM），实证检验政府引导基金对地区经济增长、风险投资活动以及创新产出的影响。结果表明：政府引导基金可以显著促进本地经济增长、风险投资以及创新活动的发展；但周边地区政府引导基金的成立与增加会对本地经济增长和风险投资活动产生挤出效应；周边地区政府引导基金负向的间接效应削弱了本地政府引导基金正向的直接效应，造成政府引导基金对地区经济增长和风险投资活动总效应的显著性下降。结论对平衡地区间政府引导基金的竞争关系，加强国家对政府引导基金的监管与协调发展具有重要意义。

以京津冀地区13座城市为研究对象，利用2000-2018年工业及工业行业能源消耗、工业产值等相关数据，基于两阶段Super SBM模型，采用ArcGIS空间分析、空间计量模型等方法，分析京津冀地区工业及工业行业碳排放效率的时空演化特征，剖析工业碳排放效率的影响因素。结果表明：①2000-2018年京津冀地区工业碳排放效率不断提高，空间格局由“中心高，四周低”向“高值区带状集聚，低值区分散”转变，城市间工业碳排放效率差异减小。②工业行业间碳排放效率差异大，不同行业碳排放效率空间格局差异显著。③生产力水平、工业研发投入、对外开放水平对工业碳排放效率具有正向推动作用，且这种作用持续增大；工业化水平与工业碳排放效率由显著负相关转变为不显著相关；能源消费强度与工业碳排放效率始终呈负相关，但这种负向作用逐渐降低；重工业水平、能源消费结构与工业碳排放效率由不显著相关转变为显著负相关。

开发区重复建设、无序扩张是长期以来困扰中国经济持续健康发展的重要问题。文章基于2004-2014年100个城市数据，采用空间面板模型，以国家级经开区为例从空间策略互动视角考察了地方政府热衷推动开发区建设的行为动机。研究发现：(1)中国地市级政府在建设开发区上会充分参考“邻居”城市的行为作出自身决策，并且这种空间效应在地理距离相近的同级城市间更为显著。具体而言，如果地理邻近城市平均建设10个新的开发区，本市往往会相应建立5个开发区。(2)相对东部来说，中西部城市间在建设开发区上的空间策略互动更强，并受到经济发展水平、产业结构、基础设施、人力资本等因素的影响。(3)进一步的经验检验表明，财政分权和中央政府主导下的政绩考核带动了地方政府招商引资的空间竞争，强化了地方政府推动建设开发区上的策略互动。文章的研究发现在一定程度上反映和解释了“开发区热”的本质特征，揭示了地方政府合作困境的根源。由此，应从政绩考核体制、财税体制、地方债务管理体制等方面采取有效的改革措施，严格控制地方政府过度建设开发区的盲目竞争行为。
