The financial magazine Caijing recently published a research results that when the credit is relatively low or moderate proportion of the financial sector employment, there will be higher level of debt that promotes economic growth. However, once the threshold is exceeded, finance has become a drag on the economic growth. If the above research results are well-established, it would be significant for a country's economic policy and financial policy. At present, the Chinese economy is not financial industry based. China should rethink the question of how to adjust the relationship between the financial sector and the real economy in an economic system dominated by the real economy, especially in manufacturing, and how should it allocate financial resources for the real economy, as well as to what extent should the financial industry be encouraged to innovate and develop.
