If you do research in the future, this scientific economics plus mathematical statistics is very helpful. Learning economics is a waste of time if you don't plan to continue your studies after graduation. Just like the basic course of Marxist economics in Southwestern University of Finance and Economics, many high-scoring candidates are cheated to learn Marxism every year. After graduation, half of the students continue to study Marxist political economy.

If you want to engage in securities and futures business, you'd better enter first-tier cities (Beijing, Shanghai and Shenzhen). After all, the financial industries in Chengdu and Chongqing are not very developed, and exchanges and futures exchanges should not move to Chengdu and Chongqing in a short time. You are mainly engaged in traditional financial business after graduation. Personally, I suggest you consider Shenzhen University, which has a good school environment and various conditions (refer to Hong Kong University of Science and Technology for money and education) and will develop greatly in the future.
