In this study a comprehensive multivariate time-series model is built to explain American foreign policy toward the People's Republic of China, during the cold war era from 1948 to 1989.

The main task of this thesis is to investigate economic implications of U.S.- China trade. The study period covers from 1972 to 1992. Data are available from International Financial Statistics, Survey of Current Business, Statistical Yearbook of P.R.China. Various hypotheses are employed to explain the basis and gain of trade, the impact of trade on both economies, and the major determinants of bilateral trade flows. This thesis contains five parts: I. Introduction; II. Outlook; III. Theoretical Analysis; IV. Empirical Study; and V. Conclusion. The major findings of this thesis are that both countries have gained advantages from trade and have also faced some unpleasant problems; several widely recognized theories serve as good approaches to understand these issues; the time series distributed lag models are helpful in explaining the determinants of trade flows.
