Why is Suzhou's heavy industry developing so fast?

The first is the transfer of Shanghai industry to township industry.

The second is the spread and opening of international industries to China.

The third is whether the industrialization of China must go through the stage of heavy industry, which is an important rhythm point, and this point has been trampled on by Suzhou. It's not easy. Suzhou has always been a relatively developed area of light industry, but around 2000, heavy industry surpassed light industry.

The fourth is the birth of traditional industries and high-tech industries. The above should be the reasons, please forgive me for the shortcomings ~ ~ I hope LZ is satisfied ~ ~
