What does economic transformation mainly mean and its significance?

Economic transformation mainly refers to changing the existing mode of economic development. We divide it into extensive economic and intensive economy. In fact, economic transformation now refers to the transformation of economic development mode from extensive economic to intensive economy. In view of the lack of knowledge, we can only make a simple explanation: 1) A remarkable feature of extensive economic is that "high input leads to high output", but this is different from some high-tech industries (such as aerospace), and most of its high input is at the expense of the environment or other things in exchange for GDP growth. We can easily find that in this economic development model, input and output are in direct proportion, that is, "the more input, the more output". 2) Intensive economy refers to relying on advanced production technology to obtain greater production profits with less investment. What we usually call "green economy" and "low carbon economy" should be a model of this intensive economy ...? Extensive economic's transformation into an intensive economy is the embodiment of Scientific Outlook on Development, which is of long-term significance to a country's sustainable development from a macro perspective. A reasonable mode of economic growth is conducive to enhancing the stamina after economic development and plays an extremely positive role in maintaining the sound and rapid development of the national economy.
