What are the guiding ideology and main contents of the traditional development model?

What do you mean? Agriculture, commerce, handicrafts ...?

Can you add some explanations?

If it's just such a general question, I can only give one or two simple answers. The traditional development mode refers to the small-scale peasant management mode in China for more than 1000 years, which changed from extensive to introverted, but it did not cause the great development of China in modern times. In the words of the historian Mr. Huang Zongzhi, there is no development and growth. The guiding ideology is the doctrine of emphasizing agriculture and restraining commerce represented by Confucianism, and its main content is to increase cultivated land and population, and finally increase taxes.

I recommend you to read a book, The Crisis of Normative Understanding of China Studies by Mr. Huang Zongzhi. You can have a look and have some understanding of this problem.
