According to the general macroeconomic growth model, the increase of material capital stock can improve economic growth in a short time before the economy reaches a stable state, but after reaching a certain stage, it can only rely on improving production capacity, that is, improving total factor productivity. For example, after World War II, European countries developed rapidly through capital reconstruction, but then economic growth gradually slowed down.

As for the core of improving productivity, you should refer to how to improve total factor productivity. In this case, it mainly depends on the technical level of production and needs innovation. There are several innovative models. One is the model like the United States, such as the emergence of high-tech products like FACEBOOK, Oracle Bone Inscriptions and Google. The other is Germany's Industry 4.0, which mainly relies on manufacturing. As for how to improve the innovation ability, of course, it lies in the cultivation of innovative talents.
