中文摘要：

基于长江上游地区第二产业,以理论假设和实证分析为线索进一步研究了产业创新问题。产业创新是指一个构成产业自身发展所需的各要素的创新和系统与环境创新的集合;产业创新的实现更多地表现为一种极化和边缘化效应：产业创新兴起与产业成长循环互动使产业集聚萌芽并优化;产业创新极化与产业繁荣循环互动使产业集聚强化;产业创新边缘化与产业衰退循环互动使产业集聚衰落分化。

英文摘要：

Based on the secondary industry in the upstream of the Yangtze River, the issue of industrial innovation is further discussed under theoretical hypotheses and empirical analysis. Industrial innovation is realized more shown in agglomeration effect and marginalization effect. The boom of industrial innovation and recycling interaction of industry growth make the industrial clustering sprout and optimize. The agglomeration effect of industrial innovation and recycling interaction of industrial prosperity make the industrial clustering intensified. The marginalization effect of industrial innovation and recycling interaction of industrial recession make the industrial clustering decline and decentralized.
