从城市经济总量比较看西部城市的差距——以15个副省级城市为例

总体上成都虽然与经济较发达的广州、深圳等城市相比还有很大差距,但与其他城市相比还是有很大的优势和潜力,在经济总量、投资水平、消费水平、物流市场上已经具备一定的优势,当前的主要问题是经济增长速度慢、人均经济水平低、资本运用程度不高、产业结构不合理、工业企业效益差以及对外贸易规模小和吸引外资力度不足。西安虽然是西部尤其是西北地区经济较为发达的城市,但与其他城市相比,无论是经济总量、经济增长速度、人均发展水平、产业结构、企业效益、市场活跃程度、资金运用、对外贸易、吸引外资和科技成果运用等各个方面都还存在着很大差距,需要进行全面的振兴和发展,并对经济结构、市场发育、区域环境、基础设施进行全面整合和调整,否则,西安与其他副省级城市的差距将会越来越大。

Low-carbon scenario and technologies in modern city——Case study of Shenyang

From a multi-dimensional perspective of economic development,carbon dioxide and industrial pollutant emission and resource consumption in the case study of Shenyang,this paper analyzes the resource consumption and environmental impact in the process of urban economic development and low-carbon transition and evaluates the emission reduction potential and scenario of various technologies. The results show that city plays a key role in global low-carbon economic construction,and it is pointed out that emission reduction technology in urban scale can reduce total amount of carbon emission to substantial extent. From the aspect of future development,the input of technology and economic growth pattern should be strengthened so as to realize economic development as well as the total amount reduction of pollutant emission.
