54. Many aspects of the demographic transition, global economic development and globalization have influenced opportunities for the intergenerational exchange of knowledge, ideas and resources. The increase in lifespan implies that many adults may be able to share knowledge and resources with younger generations over a longer period of time. In recent times, greater longevity has resulted in situations where many older people live for longer periods in some form of dependency on younger generations. On the other hand, trends in globalization and development have resulted in situations where many young people are cut off from their families. In many developing countries and countries with economies in transition, it is the ageing population that is dominant in rural areas owing to the exodus of young adults. Older persons may be left behind without the traditional support of families and even without adequate financial resources. While older persons lose opportunities to receive support from younger members of families, younger persons also lose opportunities to benefit from the knowledge and guidance of older members of their families.
54. 人口结构的转型、全球经济发展以及全球化的诸多方面都对知识、思想和资源的代际交流机会产生了影响。人的寿命提高，意味着许多成年人可以有更久的时间同年轻的几代人分享知识和资源。近些年来，由于人的寿命延长，许多老年人以某种方式依赖年轻几代人生活的时间变得更长。但另一方面，全球化和发展的各种趋势使得许多青年人离开家庭。在许多发展中国家和经济转型国家，由于年轻的成年人大量外流，农村地区的人口老龄化十分严重。老人留在家里，可能失去传统的家庭支持，甚至没有足够的经济来源。一方面，老年人失去获得年轻家庭成员支助的机会，另一方面，青年人则失去从老年家庭成员获得知识和指导的机会。
