基于DEA的四川省工业用地利用效率研究

Research on Industrial Land Utilization Efficiency in Sichuan Province Based on DEA Model

研究目的:合理使用土地资源,关键之一在于工业用地利用效率,测算四川省15个地级市工业用地利用效率,以期为成渝地区双城经济圈发展优化资源配置,提高工业用地利用效率提供参考。研究方法:基于DEA-BBC模型并利用四川省15市2016年~2019年相关工业数据从投入–产出角度建立工业用地利用效率评价指标体系并进行数据处理。研究结果:在测算出结果的基础上发现:1) 大部分城市的纯技术效率与规模效率变化不同步,15市2016~2019年平均效率值变化小,规模效率值较高,工业用地利用效率不平衡,仍有较大的提升空间。2) 成都市、德阳市和绵阳市等老工业城市综合效率值连续4年低于平均值,处于全省低段位水平,工业用地利用效率整体水平不高。3) 雅安市、资阳市连续4年技术、综合和规模效率值均保持为1,工业用地利用效率较高。研究结论:四川省内部经济发展不均衡,仍需要对城市土地用途实施严格有效的监管,持续推进区域内部产业发展协同协作。

The purpose of the study is to measure the industrial land use efficiency of 15 cities in Sichuan Province, with the expectation of providing reference for the development of the Chengdu-Chongqing Economic Circle to optimize the allocation of resources and improve the efficiency of industrial land use. The research method is based on the DEA-BBC model and to utilize the relevant industrial data of 15 cities in Sichuan Province from 2016 to 2019 to establish an evaluation index system for the efficiency of industrial land use from the input-output perspective and to process the data. The results of the study indicate that 1) The changes in pure technical efficiency and scale efficiency of most cities are not synchronized, with small changes in the average efficiency value of 15 cities in 2016~2019, higher scale efficiency values, and unbalanced industrial land use efficiency, which still has large room for improvement. 2) The comprehensive efficiency values of old industrial cities such as Chengdu City, Deyang City and Mianyang City have been lower than the average value for four consecutive years, which is at the low segment level of the province, and the overall level of industrial land utilization efficiency is not high. 3) The technical, comprehensive and scale efficiency values of Ya’an and Ziyang have remained at 1 for four consecutive years, with high industrial land utilization efficiency. The study concludes that the uneven economic development within Sichuan Province still requires the implementation of strict and effective regulation of urban land use and the continued promotion of synergistic collaboration in industrial development within the region.
