供给侧改革是当前的热点问题,加深其理论研讨十分必要,文章从产品生命周期的角度,试图对此做一些有价值的探索.作者认为,单纯的需求侧管理易导致社会供需出现结构性错位在紧缩需求时出现有效供给的严重短缺,在扩张需求时出现大量的低效供给与无效供给.为了解决这一问题,有必要根据产品的生命周期,科学设计供给侧管理政策来配合需求侧管理,从而更好地理顺政府与市场的关系,淘汰落后产能并实现产业升级,使社会供给体系更好地适应需求结构的变化.

英文摘要：

The supply -side reform is a hot issue at present, and it is necessary to deepen the theoretical research. The article, from the perspective of product life cycle, attempts to make some valuable exploration in this field. It argues that pure demand-side management may lead to a structural dislocation of social supply and demand： a serious shortage of effective supplies may happen when demand is in austerity , while a large number of inefficient and invalid supplies may emerge when demand is expanding. To solve this problem , it is necessary to design certain scientific supply -side management policies to match demand -side management according to product life cycle, thus to better rationalize the relationship between the government and the market, to eliminate outdated industrial capacity, to achieve industrial upgrading and to make social supply system better adapt to the change in demand structure.
