The aim of this study is to analyze the impact of the EEC on one border region, the French province of Alsace, through an examination of its economic and social transactions with West Germany since 1960. No great increase in Alsatian social ties with Germany has been observed, but there has been considerable growth in economic contacts, leading to a new prosperity for the province. Alsatian economic integration with the rest of France is not increasing as fast, but it has not been noticeably weakened. Alsatian elite and public opinion generally supports the growth of economic bonds with Germany, largely because of their contribution to economic welfare. Transaction and attitude data indicate a continuation of the present trend of important economic, but only limited social, ties between Alsace and its German neighbor.
