Although the economic level of Yancheng and Shaoxing is similar, Yancheng can only rank seventh in Jiangsu, which belongs to the lower-middle level. Shaoxing can rank fourth in Zhejiang, almost third. The status in the province is completely different. The GDP of Yancheng in Jiangsu Province is less than half that of Nanjing, only half that of Wuxi and one third that of Suzhou. The gap in economic strength is still obvious.

Even Xuzhou, as the city with the strongest comprehensive strength in northern Jiangsu, has a GDP 5800 higher than that of Wenzhou. In this way, Jiangsu ranks fifth, and a large number of people will definitely migrate to cities with strong economy in southern Jiangsu. This is determined by the city status of the place.

On the other hand, Jiangsu cities are generally strong, and the gap between cities is even greater. Suqian, which ranks first in Jiangsu, ranks eighth in Zhejiang, killing four Zhejiang cities, but its GDP is only half that of Yancheng. Wuhu, the second strongest city in Anhui, can only rank third from the bottom. Jiangsu's urban strength is relatively strong, which makes its corresponding status look obviously low. Nantong can be the boss in Anhui, but its position in Jiangsu is not ideal.
