Abstract	Whether a drug can become a blockbuster is a generally concerning problem for pharmaceutical companies when they deal with product research and development. This paper randomly selected 100 drugs from all NMEs and BLAs approved by FDA from 1993 to 2009 as the study samples, which are evaluated by the selected proxy variables (indicators) with further Pearson Chi-Square correlation and logistic regression analysis. It was found that the proxy variables "Aging", "Wealthy" and "Long-suffering" are three major factors affecting the demands while "Brand" is the major factor affecting the substitutability(R =0.834). The impact factors chosen in this paper will be useful in predicting future blockbusters.
