Impossible, not to mention the stagnation of Shanghai's economy, it will take Chongqing five years to catch up with Shanghai's level, not to mention that the focus of the country is not inland, but coastal. Just as Guangzhou can't catch up with Shanghai for a lifetime, there may be hope for Chongqing to catch up with Guangzhou and Shenzhen. However, if we catch up with Shanghai, we will all be municipalities directly under the central government. Even if we get the same treatment, then everyone will advance at a constant speed and never catch up. Needless to say, Shanghai's policy is much better than Chongqing's, and there is no way to distinguish between the coastal areas. Unless the country stops developing Shanghai, Chongqing can catch up with Shanghai in five years.
