In order to explore the phenomenon that the leisure consumption has rapidly grown in China in recent years, a survey which is based on the hypothesis built by Werner Sombart that the secularization of love facilitates the endless consumption in the process of the formation of capitalism is conducted to prove that there is a linear relationship between the level of the leisure consumption and the extent of sexual liberation. The research through the network questionnaire survey on college students in colleges of Chongqing municipality, based on the completely random sampling method, gets 324 valid samples and analyzes them in the method of multiple stepwise regressions. As a result, the research proves that the leisure consumption of college students is remarkably correlated linearly with the self-judgment of sexual liberation (β1 = 0.101) and the number of sexual partners (β7 = 0.181) by controlling the noise variable including gender, age, college, major, educational attainment, single-parent family or not and religion. It’s demonstrated that the extent of sexual liberation exactly raises the level of leisure consumption (R2 = 0.176).
