【摘要】：以中国30个省会城市(台北和拉萨除外)、直辖市为研究对象,设计了定量评价城市形态和城市环境支出绩效的指标。城市形态的定量指标设计为"紧凑率"和"伸延率",统计结果表明:城市紧凑率的均值呈现出明显的下降趋势,城市伸延率呈现出较大波动。城市环境支出绩效从投入和产出两方面设定评价指标,采用考虑非期望产出的评价模型,对各城市的环境支出绩效进行评价,结果表明绩效较好的城市不足40%,且大部分城市的环境支出绩效值都在0.8以下。为了进一步研究城市形态与城市环境支出绩效的关联机理,采用面板分析模型的个体固定效应模型进行分析,结果表明:城市的紧凑率与城市环境支出绩效显著正相关,而城市伸延率与城市环境支出绩效未通过显著性检验。最后,提出了合理控制城市规模,推行紧凑型城市发展模式,优化城市结构和功能等方面的政策建议,旨在提高城市的环境支出绩效。
[Abstract]:Taking 30 provincial capitals of China (except Taipei and Lhasa) and municipalities directly under the Central Government as the research objects, an index for quantitative evaluation of urban morphology and urban environmental expenditure performance was designed. The quantitative index of urban form is designed as "compact ratio" and "elongation rate". The statistical results show that the mean value of urban compact rate is obviously decreasing, and the urban elongation rate is fluctuating greatly. The performance of urban environmental expenditure is evaluated from two aspects of input and output, and the evaluation model considering non-expected output is adopted to evaluate the performance of urban environmental expenditure. The results show that there are less than 40 cities with better performance. And the environmental expenditure performance of most cities is below 0.8. In order to further study the correlation mechanism between urban morphology and urban environmental expenditure performance, the panel analysis model is used to analyze the individual fixed effect model. The results show that the compactness of a city is significantly positively correlated with the performance of urban environmental expenditure. However, the urban elongation and the performance of urban environmental expenditure did not pass the significance test. Finally, the paper puts forward some policy suggestions on how to control the scale of the city reasonably, carry out the development mode of the compact city, optimize the structure and function of the city, so as to improve the performance of the city's environmental expenditure.
