looking forward an economic analysis on the milk power issue in china

Tweet

as is reported,the milk powder issue has drawn the most attention at the moment.it has raised discussions in many fields,such as moral,law and so on.with the further research,more and more people are found to be responsible.butin my opinion,it is not a fault of a particular person or enterprise.it's the whole system that is to be blamed.and source of the evil can be originated to the unexpected high profit inthe milk industry. as a student majoring in finance,i really want to use economic tools to reach a comprehesive analysis on it.so,whoever is willing to give me a guideline is sincerely appreciated ~thanks~
