"why Do Countries Armed" Replicated Study

War and peace has always been the core of international political study, with armament a particularly important research focus. However, most of the researches are content with rational theorizing, lacking in evidential inquiry. Using quantitative methods, this article explores the political, economic and cultural influence on armament, in post-Cold War era, through improvement on model modification, data updating and analytic tool of previous related research.This article is inspired by Payne’s1989work why nations arm. He chose data which dated from1970to1982and includes137nation samples as targeted research selection. Then, based on quantitative methods, he analyzed the effect of political, economic and cultural factors on armament. It’s worth noting that the methodology applied and its focus on culture made it unique from previous research. Nevertheless, his research in Cold War can still be improved by model modifying, data updating and analytic methods perfecting.This research selected data in period between1990and2005, covering up to162. Payne’s Modal has been meliorated by eliminating out-of-date variables and adding new variables. This article subsequently examined all independent variables’ influence on dependent variable with systematically statistical method, successively involved univariate statistical analysis, bivariate correlation analysis and multiple regression analysis of the full sample.Quantitative research showed that economic factors was most significant in explaining armament, while political and cultural factors were shared with the similar statistical significance, which could be the production of the combination between loose of tension in international environment after Cold War and armament trend towards capital orientation.
