The widespread application of Internet of Things technology, new broadband mobile networks, cloudy computing, and other new information technologies on the Internet has promoted the development of “smart cities.” The essence of the “smart city” is to make full use of advanced information technology to realize the intelligent management and operation of the city, thereby creating a better life for the urban people and realizing the harmonious and sustainable development of the city. This article is aimed at studying the innovation of intelligent enterprise management models in the context of smart cities. This article first analyzes and briefly describes the theoretical knowledge of the “smart city” and the current domestic development, then proposes the technology of data warehouses, and finally uses the multiple linear regression formula for analysis. The experimental results of this paper show that in the context of smart cities, the intelligent management model of enterprises has played an important role in the development of enterprises, which is 51.7% faster than the traditional model, and the accuracy is as high as 92.3%.

In recent years, China has entered a period of rapid urban development, but most of the cities with rapid development still have ground hardening, which makes it difficult for rainwater to penetrate and discharge. In order to achieve the rapid drainage of accumulated water in the city, nanotechnology was introduced, and permeable concrete based on NC and NS nanomaterials was proposed. Combined with finite element analysis, the permeable properties and mechanical properties of permeable concrete mixed with nanomaterials were analyzed. A comprehensive performance analysis of pervious concrete shows that the viscosity of permeable concrete mixed with nanomaterials is significantly higher than that of non-mixed pervious concrete, and the permeability coefficient of permeable concrete mixed with nanomaterials can reach 0.43 cm/s. A finite element analysis shows that the incorporation of nanomaterials can improve the compressive strength of permeable concrete. At the same time, under a rainwater environment simulation, the rainwater retention time of pervious concrete is only 2.35 s. The above results show that the incorporation of nanomaterials into pervious concrete can improve the water permeability of pervious concrete, improve the mechanical properties of pervious concrete, and increase its service life, which is of great significance to urban development and urban management.
