基于文本分析的西北地区工业绿色转型政策导向研究

以西北地区城市为研究区域，以2008—2017年地方政府颁布的政策文件为研究对象，运用TF-IDF文本分析法，探讨了10年间西北五省地方政府工业绿色转型的政策导向，以期为中国西北地区城市和其他地区城市的绿色转型发展提供经验和借鉴，并丰富国内关于城市绿色转型的研究内容。西北地区政府出台的关于工业绿色转型的政策数量整体上呈上升趋势，陕西和甘肃出台的相关政策数量始终排在前列，宁夏和青海则一直较少。通过对政策文本进行关键词提取，得出各省份中“建设”“企业”“质量”“污染”等词语权重较大，部分省份中“扬尘”“燃煤”“锅炉”“机动车”等词语的权重排名也较靠前。西北地区出台工业绿色转型相关政策的城市数量呈增长趋势，各市较为重视效率提升和安全生产，对于环境保护与科技创新的政策导向力度明显不足。

POLICY ORIENTATION OF INDUSTRIAL GREEN TRANSFORMATION IN NORTHWEST CHINA BASED ON REFERENCES ANALYSIS

This paper, based on polices issued by local government from 2008 to 2017 in Northwest China, uses TF-IDF method to study the policy orientation of industrial green transformation in five northwestern provinces in recent ten years aiming at offering experiences for China's northwestern or other areas in green transformation, and enriching the research content of urban green transformation. The number of issued related policies by local governments is increasing in Northwest China, Shaanxi and Gansu sitting on the top, while Ningxia and Qinghai having less. The key words with bigger weight in the policies include “construction” “enterprise” “quality” and “pollution” in five northwestern provinces, also include “dust” “coal” “kiln” and “vehicle” in some provinces. Cities issuing industrial green transformation policies are also rising in number. The governments pay more attention on efficiency and production safety, but less on environmental protection and innovation policy orientation.
