First of all, the status is different. Shanghai is a municipality directly under the central government, and Shenzhen is only a sub-provincial city in Guangdong Province. Shanghai, known as Paris of the East, has a long-standing reputation, while Shenzhen, with a history of only 40 years, is a rising star among the world cities. Shanghai's population and GDP rank first in domestic cities, while Shenzhen's GDP ranks third in the country, and its population ranking is lower than that of Shanghai. Most of Shanghai is composed of state-owned enterprises, while more than 90% of Shenzhen is private enterprises. Shenzhen's economy has more vitality and development potential. Shanghai has a long history and has made great contributions to the economic development of new China. Its GDP once accounted for 1/6 of the whole country. Shenzhen is an inclusive city with people from all corners of the country. Shenzhen is the bridgehead of reform and opening up. It is full of innovative spirit, full of vitality, high degree of marketization and high quality of economic development. Per capita GDP, GDP per unit area, energy consumption per unit GDP, annual number of patents, import and export volume and other indicators have been the first in China for many years, and it is a more imaginative place.
