我国工业棕地再开发影响因素研究

The Influencing Factors of Industrial Brownfield Redevelopment in China

随着我国城市建设由增量开发进入城市更新时代,工业棕地的再开发也将成为未来城市更新的重要内容,而现有研究往往更重视工业用地再开发的经济收益而对其环境影响关注不足。本文在总结国内外棕地再开发可能性影响因素研究的基础上,分析我国工业棕地再开发的模式特征,运用2019—2022各省市自治区定期公布的建设用地土壤污染风险管控和修复名录,聚类分析我国各地级市工业棕地再开发的特点,并运用多元线性回归的方法实证研究我国各地区工业棕地再开发可能性的影响因素。研究发现:(1)我国工业棕地再开发形成了明显的地方政府积极主导的特点;(2)我国各地区工业棕地再开发的情况可分为四类,分别为高修复发达城市、中等修复较发达城市、低修复较不发达城市以及高修复较不发达城市;(3)地方政府财力、城市产业结构调整以及房地产开发投资水平等因素影响我国不同地区的工业棕地再开发可能性。基于以上研究发现,本文提出完善土壤污染防治基金的建立和使用,建立多层级的基金并向财政收入水平较低的地区倾斜以及鼓励多元主体参与工业棕地再开发等政策建议。

As China's urban development enters the era of urban renewal,the redevelopment of industrial brownfield will also become an important element of future urban renewal,while existing studies often pay more attention to the economic benefits of industrial land redevelopment and pay insufficient attention to its environmental impact.On the basis of summarizing the research on the factors influencing the possibility of brownfield redevelopment,the paper analyzed the characteristics of the mode of industrial brownfield redevelopment in China,use the list of risk control and remediation of soil pollution on construction land regularly announced by provinces,municipalities and autonomous regions in 2019—2022,cluster analyze the characteristics of the redevelopment of industrial brownfield in each province in China,and use the method of multivariate linear regression to empirically study the factors influencing the possibility of redevelopment of industrial brownfield in each province in China.The study found that(1)the redevelopment of industrial brownfield in China is characterized by the pro-active role of local governments;(2)the redevelopment of industrial brownfield in various regions of China can be divided into four categories,namely,highly remediated developed cities,moderately remediated developed cities,low remediated developing cities and highly remediated developing cities;(3)the financial strength of local governments,industrial restructuring,as well as the level of investment in real estate development affect the redevelopment possibilities of industrial brownfield in different regions of China.Based on the above findings,this paper proposes to improve the establishment and utilization of the soil pollution prevention fund,establish a multi-level fund,tilt the fund to areas with lower levels of financial income,and encourage the participation of multiple actors in the redevelopment of industrial brownfields.
