The coordinated development of smart cities has become the goal of world urban development, and the railway network plays an important role in this progress. This paper proposes a solution that integrates data acquisition, storage, GIS visualization, deep learning, and statistical correlation analysis to deeply analyze the distribution data of companies collected in the past 40 years in the Yangtze River Delta. Through deep learning, we predict the spatial distribution of the company after the opening of the train stations. Through statistical and correlation analysis of the company’s registered capital and quantity, the urban development relationship under the influence of the opening of the railway is explored. Going forward, the use and application of such analysis can be tested for use and application in the context of other smart cities for specific aspects or scale.

Spatiotemporal Heterogeneity

The long-term changes of the relationship between nighttime light and urbanization related built-up areas are explored using nighttime light data obtained from the Defense Meteorological Satellite Program/Operational Linescan System (DMSP/OLS, data before 2013) and the Suomi National Polar-orbiting Partnership Visible Infrared Imaging Radiometer Suite (NPP/VIIRS, data after 2012) and information of the spatiotemporal heterogeneity of urban evolution. This study assimilates two datasets and diagnoses the spatial heterogeneity in administrative city scale based on built-up area tendencies, temporal heterogeneity in pixel scale based on nighttime light intensity tendencies, and GDP associated spatiotemporal variability over the Yangtze River Delta comparing the first two decades of this century (2001–2010 versus 2011–2019). The analysis reveals the following main results: (1) The built-up areas have generally increased in the second period with the center of fast expansion moving southward, including Suzhou-Wuxi-Changzhou, Hangzhou, Ningbo, Nanjing, and Hefei. (2) Urban development in the original city core has saturated and is spilling over to the suburbs and countryside, leading to nighttime light intensity tendency shift from a “rapid to moderate” and a “moderate to rapid” development (a “hot to cold” and a “cold to hot” spatial clustering distribution). (3) The tendency shifts of built-up area and nighttime light intensity occur most frequently in 2010, after which the urban development is transforming from light intensity growth to built-up area growth, particularly in the developed city cores. The urban agglomeration process with nighttime light intensity reaching saturation prior to the urban development spreading into the surrounding suburbs and countryside, appears to be a suitable model, which provides insights in addressing related environmental problems and contribute to regional sustainable urban planning and management.

The Yangtze River Delta

Yangtze River Delta is one of the most developed regions in China. In recent years, environmental protection industry has developed rapidly, and the total investment has also kept increasing, and the investment structure has been improving, and the mode of financing increases. But there are still some problems in the current investment and financing of environmental protection industry in the Yangtze River Delta. Based on in-depth analysis of the causes of the problems, this paper put forward some countermeasures and suggestions to solve the problems in investment and financing of environmental protection industry in Yangtze River delta.

The Yangtze River Delta

As the main form of new urbanization, urban agglomeration regional integration has gradually become an important carrier and platform for leading China’s economic transformation and upgrading. The Yangtze River Delta urban agglomeration is one of the largest urban agglomerations in China, and its integrated and coordinated development is of great significance to China. Taking the Meilong Town of Shanghai as an example, this paper summarizes the impact and role of high-quality urban development under the integration of the Yangtze River Delta. Through the analysis from the perspectives of spatial structure, land use layout, urban renewal, and water grid bureau, the urban development under the integration of the Yangtze River Delta was initially explored.
