The problem with the above thesis is that all of this is a 'secondary economy strategy' i.e. it's good for catching up, it's not very good for surpassing.China is past the "catching up stage" in the industrialized areas. Median income in Shenzhen is comparable to US median income. Current policy is to increase domestic consumption and have an internal economy which is less dependent on exports, while still dominating key international markets. This is called "Dual Circulation".
Here's a summary of the 14th Five Year Plan.[1] "President Xi called for building “independent, controllable,
secure, and reliable supply chains to ensure industrial and
national security with access to at least one alternative
source for important products.” President Xi said China
should “use existing global dependencies on China as a
counterweight to pressures to shift manufacturing out of
China” and “use the pull of China’s market to attract global
resources and deepen global dependence on China.”"
The "Made in China 2025" plan, issued in 2015, listed 10 sectors where China wanted to be self-sufficient by 2025.
- New information technology
- High-end numerically controlled machine tools and robots
- Aerospace equipment
- Ocean engineering equipment and high-end vessels
- High-end rail transportation equipment
- Energy-saving cars and new energy cars
- Electrical equipment
- Farming machines
- New materials, such as polymers.
- Bio-medicine and high-end medical equipment.
Most of those goals have already been achieved.
Again, none of this is a secret. It's stated policy of the PRC.
