You will significantly improve your chance if you can get into a decent market program (economics, statistics or maybe finance) or a not so top PhD program in US(this is the most important part, in US, not China) in the above major and get a 4.0 GPA.
The above has been proved by the success of several(probably a lot of) people.
Also, you may consider some other majors such as statistics, economics and management, etc. There is very tough competition in the finance PhD application. And also the competition for faculty positions is extremely tough. For example, the ratio of faculty job opening to applicants at some top school was around 2/500 in finance, and around 2/20 in accounting. But finance PhD can easily find jobs in the industry. So there are always pros and cons.
Think seriously about what you want to do: academia or industry, pick a major, and then make a plan. Follow your plan step by step.
