Understanding Competition in Social Space: Religious Congregations in Manhattan, 1949 to 1999
研究了1949至1999年曼哈顿宗教会众间的竞争，发现附近神学不同的会众越多，该会众越少做广告；神学相似的会众增加则广告增多。
Competition between social units has long been central to sociological theories of change. Understanding it has become particularly important in the sociology of religion with the theory of religious economies, a market model of religious change. Existing empirical tests of the theory are limited by (1) ambiguity regarding which religious groups are expected to compete with which other groups, and/or (2) a neglect of the local level (competition among congregations). Using an original compilation of the life histories of religious congregations in Manhattan from 1949 to 1999, I conduct event-history analyses that avoid those limitations. The chief results are the following: (1) the more congregations there were near a given congregation that were theologically dissimilar to that congregation, the less likely that congregation was to advertise; (2) when there was an increase over time in the number of nearby congregations that were theologically similar to the focal congregation, that congregation became more likely to advertise; and (3) when there was an increase over time in the number of nearby congregations that were theologically dissimilar to the focal congregation, that congregation became less likely to advertise. Implications for the study of religion include modifications of religious-economies theory; broader implications speak to understanding the social units that compete and what drives competition.
