Research on Regional Urban Economic Development by Nightlight-time Remote Sensing

TL;DR

This paper uses night-light remote sensing images from 1992 to 2013 to analyze China's regional economic development and urbanization trends, revealing rapid growth and regional disparities.

Contribution

It applies night-light remote sensing data combined with GIS analysis to study urban expansion and economic development in China over two decades.

Findings

China's urbanization speed is at its peak.

Significant regional development potential exists.

Regional development imbalance needs attention.

Abstract

In order to study the phenomenon of regional economic development and urban expansion from the perspective of night-light remote sensing images, researchers use NOAA-provided night-light remote sensing image data (data from 1992 to 2013) along with ArcGIS software to process image information, obtain the basic pixel information data of specific areas of the image, and analyze these data from the space-time domain for presentation of the trend of regional economic development in China in recent years, and tries to explore the urbanization effect brought by the rapid development of China's economy. Through the analysis and study of the data, the results show that the urbanization development speed in China is still at its peak, and has great development potential and space. But at the same time, people also need to pay attention to the imbalance of regional development.
