1. Panjin is a fourth-tier city in administrative division, because the urban population and area are not dominant, but its economy is among the best in Liaoning Province. Of course, it is not as good as Shenyang and Dalian. Panjin mainly takes oil exploitation and processing as its main economic industry. Any city with resources as its pillar industry will decline one day, and Yumen is the most representative one. In order to avoid this situation, Panjin City is also trying to reform and speak out. 2. Panjin's position in Liaoning is still good, with obvious advantages in petrochemical industry and equipment manufacturing, and it is an excellent student in the province in terms of economic aggregate and per capita level. 3. As long as Panjin handles the key issues such as industrial structure adjustment, population growth, talent attraction and coordinated development of regional economy, the future of Panjin will be very bright, and it is also possible to maintain the current city level (third line) to a higher city level (second line).
