Sounds your undergraduate degree is from an "average" institution in China. Also, the gpa for the major courses in your master's program is low. Thus, if you will apply for fin., I would suggest that you consider ranked in the 50-100 range.
Since your undergraduate major is int'l econ and trade, you may want to consider int'l business programs or programs with an int'l component, such as, UIUC, Temple, Miami, GWU, Ohio State, South Carolina, UTD, UT-El Paso, and Old Dominion. PhDs in int'l business, int'l fin, and int'l mkt are well sought after. For example, those from the UT-El Paso have been placed at research schools.
I am not so sure about the management/entrepreneurship track. But you can check them out.
我这几天看了好些学校PHD项目的网页,我发现management下面的项目,包括strategy, IB等,大部分current students 都有好些年的工作经验,不过几个中国学生没什么工作经验的。我想问下,是不是management体系下的项目会喜欢招收有工作经验的呢?是不是这样的项目其实更适合有丰富工作经验的人来读呢?
