山东省经济转型中能源强度的时空分异及其成因

SPATIAL- TEMPORAL DIFFERENCE AND ITS CAUSES OF ENERGY INTENSITY IN ECONOMIC TRANSITION OF SHANDONG PROVINCE

山东省能源强度的时间变化呈现出明显的四个阶段，文章从经济结构、能源结构、技术进步、对外开放、能源价格五个方面选取指标，与能源强度建立模型进行最小二乘估计探究其变化的成因，结果表明经济结构、能源结构影响显著，而技术进步、对外开放、能源价格也有较大影响．十七地市能源强度空间特征表现出山东半岛地区低、中西部地区高的特点，分析了其形成的原因．最后提出了提高山东省能源效率的对策建议．

The energy intensity variation of Shandong Province appears four stages obviously. And by selecting indicators reflecting economic structure, energy structure, technological advance, external open and energy price, the causes are researched using least - square method to estimate. The result shows that economic structure and energy structure are of great influence while technological advance, external open and energy price are also effective. Moreover, the spatial characteristic of 17 cities＇ energy intensity presents low in Shandong peninsula area but high in the Midwest. Also, its causes are analyzed. Finally, some suggestions are put forward to improve the energy efficiency in Shandong Province.
