Sponge City Construction and Urban Economic Sustainable Development: An Ecological Philosophical Perspective.

The Party's 14th Five-Year-Plan and the 2035 Visionary Goals point out that green and sustainable development is the direction of China's road in the present age, and provide a theoretical basis for further improvement of ecological civilization. "Sponge city" is a new type of urban construction idea in China; moving from pilot to vigorous implementation at present, it is an important element of China's promotion of green development and development of ecological civilization. At present, a number of sponge city pilot projects have been built in China, and evaluation of their effects is already a matter of urgency. The overall planning of China's current policies in sponge city construction and the specific analyses conducted by experts from both subjective and objective aspects have not been able to completely fill the gap in this regard, thus making it particularly urgent to conduct in-depth studies. Based on this, this paper discusses the performance assessment of sponge cities in China on the basis of the prediction and analysis of the development trend of sponge cities in China. In the performance assessment system, the correctness and timeliness of the index system should be considered in terms of practical effects; in the city performance assessment, the ideas of new city development such as low-carbon cities and smart cities should be combined to build a comprehensive and multi-perspective intelligent assessment system, so as to provide a strong boost to promote the development of city construction and its evaluative research. Firstly, a system-dynamic model is applied to sort out and combine its internal operation mechanism, and a set of evaluation systems based on the ecological philosophical perspective of the sponge city and urban sustainable development performance is established. Second, to improve the accuracy of the research results, parallelism tests and robustness analysis were conducted on this performance index evaluation system. The study's results show that sponge city construction has achieved good results in sustainable urban development and has contributed to future development.
