Why is the R&D capability of China’s small and medium-sized enterprises so low?

In China's non-market economic system, under the joint pressure of the government and state-owned enterprises, the average life span of China's small and medium-sized enterprises is only 5.4 years. Survival is so difficult, like a shooting star. You still let them develop it?

Don’t you see, no matter which private enterprise, as long as it works hard to become a leader in an area that the original state-owned enterprises, especially the monopolistic central enterprises, feel that it is not profitable, and develop this area. When the time comes, the central enterprises will come to harvest, hurting others with their own abilities, suppressing others with their power, and resorting to all possible means. Being "acquired" in the end is the best result. What to research and develop? In today's China, only fools do business. Either play with capital, engage in real estate, or directly sell the company to cash out after it becomes bigger. The whole family immigrated and left cleanly.
