The Political Partisanship of American Business: A Study of Corporate Political Action Committees
利用政治行动委员会捐款数据检验六种企业政治党派理论，发现区域差异理论和监管环境理论得到支持，而四种企业自由主义理论变体未获支持。
This study uses data on the contributions of political action committees to evaluate six popular theories of business political partisanship. Two theories are supported by the data: the Yankee-Cowboy theory of regional political differences among U.S. corporations and the regulatory environment theory, which views the differential relationship to government regulation as a primary determinant of political behavior. No support is found for four other theories of business political partisanship: the core-periphery theory, the inner-circle theory, the managerialist theory, and the domestic-multinational theory. The four disconfirmed theories are all variants of a perspective known as the theory of corporate liberalism, which hypothesizes a tendency toward greater liberalism on the part of the more dominant or central corporations in American society.
