This paper focuses on the effects of political ideology and party affiliation on support for more government spending on environmental protection. Pooled‐sample results show that Liberals (Democrats) are more likely to support higher government spending on environmental protection than Moderates (Independents), who, in turn, are more likely to support higher spending levels than Conservatives (Republicans). The results persist even when we control for respondents' opinions concerning whether the federal government, in general, does too little or too much. When stratifying by party, ideological divisions generally narrow, while stratifying by ideology leads to slightly wider divisions between Democrats and Republicans. Together, these results suggest that when Liberals and Conservatives form opinions about government spending on the environment, party affiliation, to some degree, dampens the effects of ideology. Between 2014 and 2018 the probability of supporting more environmental spending increased, albeit slightly, for all ideologies and parties, but more so for Liberals and Democrats.

政治意识形态，政党和对美国联邦政府在环境保护方面的更大支出的支持：1993-2018年一般社会调查的证据

本文着眼于政治意识形态和党派关系对支持更多政府环保支出的影响。汇总样本结果显示，自由党（民主党）比中度党（独立人士）更有可能支持更高的政府环保支出，而中度党（独立人士）则比保守党（共和党）更有可能支持更高的支出水平。即使我们控制了受访者关于联邦政府总体上做得太少还是太多的意见，结果仍然存在。当按政党分层时，意识形态分歧通常会缩小，而按意识形态分层会导致民主党人和共和党人之间的分歧稍大。这些结果加在一起表明，自由主义者和保守党就政府在环境方面的支出形成意见时，政党的隶属在某种程度上削弱了意识形态的影响。在2014年至2018年之间，所有意识形态和政党支持更多环境支出的可能性有所增加，尽管有所增加，但自由主义者和民主党则有所增加。
