The objective of this study is focused on the derivation of APT model, and the comparison of CAPM and APM, its empirical tests of many savants as the preparatory step for my empirical tests about Korean capital asset market in the near future. The first chapter of this study is composed of the purpose of this study. In chapter II, it is illustrated on the derivation of arbitrage pricing model (APM), and then it is studied that APM is more general and reasonable than CAPM on the ground that CAPM is a single factor pricing model of multi-factors pricing model, APM. In chaptor III, it is analyzed about the comparison of CAPM and APM APM is similar to the CAPM in that it is also an equilibrium asset pricing model, and one factor APM is same with CAPM, in analyzing one factor such as variance of risk. But APM is the appropriate and special alternatives of CAPM because APM is not only easily extended to multi-period framework on account of contending numerous factors, butt also it allows numerous factors to explain the equilibrium return on a risky asset. In chapter IV, it was investigated into many empirical tests on APM. Results of many tests found that in determining asset return by many factors, multi factor generating model, APM was confronted with the difficult problem such as factor loadings and its analysis. And it was found also that APM was a more reasonable model for explaining the cross-sectional variation in asset returns and determining factors, and the appropriate measure of risk was the sensitivity of asset returns to changes of the factor, and while, the sensitivity was analogous to the beta of the CAPM for normally distributed returns. In the last chapter V, I conclude APT will be a most important contribution in understanding the nature of asset prices. This theory has already given us a great deal of insight into asset prices, as stated above. But empirical work on implementing APT is just the early stage. As this study is a my pre-study step on APT, I think its empirical research on the Korean capital asset market is my next subject.

International marketing, which is target market that overseas market is differ from environments and given conditions with a domestic market, is infinite variety shape of market as well as is differ from language, customs, sales habit, structure of market, and system of law, is changing dynamically. It is very difficult to develop, maintain and enlarge this market without practice of efficient sales promotion. But, majority of corporations in a country cannot recognize the importance of this, actually, they had been doing marketing by rule of thumb. So corporations of our country have to pass over simply importing and exporting, they have to promote international marketing strategy with an eye for a long period including technology and sales practice. Ultimately, they have to enlarge range of overseas business in quality and quantity. International marketing which is more advance and progressive sales strategy, has to collect overseas markets information speedily and exactly, and practice more specific marketing mix strategy based on collecting marketing information.
