法律权力的实现是一个社会选择的过程,从社会当事人的角度分析,一切选择均源于每一个人对法律的嗜好与期待。立法者偏好导致法律空缺严重制约社会当事人的行为选择方式;此外,社会分层因素、社会空间因素、社会文化因素对法律权力的实现即社会的选择过程均产生重要影响。探寻和研究法律的实效就不能无视这些因素的存在。 The realization of legal power is a process of social choice. From the perspective of social parties, all choices stem from everyone’s preference and expectation of the law. The preferences of lawmakers lead to the vacancy of law seriously restricting the choice of behavior of social parties. In addition, social stratification, social space and socio-cultural factors have an important impact on the realization of legal power, that is, the process of social selection. To explore and study the effectiveness of the law can not ignore the existence of these factors.
