西部资源型城市经济增长与能源消耗关系计量研究

Quantitative study on the relationship between economic growth and energy consumption in western resource-based cities

中国经济飞速发展,资源开发重心西移,但西部大部分资源型城市却与全国发展态势背道而驰,不断衰退。鉴于此,本文构建改进后的Solow柯布-道格拉斯生产函数方法,以西部8个资源型城市为例,重点揭示其经济发展与资源消耗规律。结果表明:定性上,西部城市经济增长与能源消耗存在正相关关系;定量上,西部资源型城市经济驱动因子各异。但整体上对能源消耗依赖性较强、科技进步率低、规模报酬递减。由此判断,西部资源型城市应立足本底条件和资源特性,把握城市发展阶段,及时调整产业结构,改变能源消费方式,加大科技、教育的投入,促进西部经济可持续发展。

With the rapid development of China s economy and the shift in the focus of resource development,most western resource-based cities have gone against the backdrop of national development.The study constructs an improved Solow Cobb-Douglas production function method,focuses on revealing the economic development and resource consumption patterns of eight western resource-based cities.The results show that there is a positive correlation between economic growth and energy consumption in western cities in qualitative aspects.In quantitative aspects,there are three characteristics of western resource-based cities as a whole:diminishing returns to scale,strong dependence on energy consumption and low rate of scientific and technological progress.So the western resource-based cities should adjust the industrial structure and the model of energy consumption,increase the investment in technology and education,promote the sustainable development of economy.
