Abstract In both developed and underdeveloped areas, many attempts have been made to alter the course of fertility through family planning intervention. Doubtless the availability of such services facilitates birth control for those who already desire to use it. Whether or not such exogenous interventions have any independent effect upon the operation of endogenous forces in the economy and society is, however, more problematical. Where fertility declines have been observed, family planning services have often been made widely available only after the decline in fertility had already set in. Nonetheless, observers have often attempted to attribute some fraction of the continuing decline in fertility to the operation of family planning activities. One especially notable case is that of Hong Kong, which provides some of the more persuasive evidence about the independent effects of family planning intervention.
摘要 在发达国家和发展中国家，人们都曾试图通过计划生育干预措施来改变生育模式。无疑，这些服务的提供便利了那些已经有节育需求的人进行节育。然而，此类外生干预措施对经济和社会内生力量的运作是否具有任何独立影响却更加成问题。在观察到生育率下降的地方，往往是在生育率已经下降之后，才广泛提供计划生育服务。尽管如此，观察家们还是常常试图将生育率持续下降的一部分归因于计划生育活动的运作。香港就是一个特别值得注意的例子，它提供了一些关于计划生育干预独立影响的更有说服力的证据。
