中文摘要：

理论分析以及转轨时期的中国经验事实均显示人口年龄结构通过消费结构对产业结构升级起作用。基于1995—2013年中国30个省（市、自治区）的面板数据的实证结果表明：消费结构确实是人口年龄结构影响产业结构的重要中间变量,消费结构与产业结构呈正向变动关系;少儿抚养比的下降和老年抚养比的提高均促进了消费结构升级,进而有利于产业结构升级。此外,人口年龄结构的需求效应及其对产业结构的作用机制和作用大小在东、中、西三大区域间呈现出明显的区际差异。

英文摘要：

Industrial restructuring and upgrading plays an important role in meeting the needs of expanding domestic demand and sustaining medium-high economic growth under the background of new normal. As demanders and consumers,different age structure leads to different consumption structure,and then this change at individual level will accumulate and cause the changes of the entire social demand structure,thereby having different effect in industrial restructuring and upgrading.Nowadays,China＇s population age structure is undergoing dramatic changes,marked by low fertility rates,demographic dividend fading：the double stacking phenomenon of″aging″and″fewer-children.″Reversely,changes in population age structure may force industrial restructuring through demand mechanism,thus,providing a new impetus toexpand domestic demand and adjust industrial structure under the new normal.Based on the above logic,this paper systematically analyzes the impact of population age structure on industrial structure through the channel of consumption structure in terms of both theoretical and empirical aspects,and reveals its mechanism of action and presents the chain transitive relation between the three.Theoretical analysis and China＇s experience during the transition period show that population age structure plays a certain role in the upgrading of industrial structure through the channel of consumption structure.Sub-regional panel regression model is established using the data set from China＇s 30provinces（including municipalities and autonomous regions）during 1995—2013,and our empirical tests show that consumption structure is an important intermediate variable through which population age structure affect the industrial structure.It is also found that there is a positive relationship between consumption structure and industrial structure.The decreasing child dependency ratio promotes the upgrade of consumption structure,thereby benefiting the upgrade of industrial structure.The rising elderly dependency ratio also p
