在分析我国地区产业多样化、技术创新与经济发展之间相互影响机制的基础上，构建联立方程组模型，并利用2003-2011年我国31个省份的面板数据进行实证检验。结果表明，产业多样化通过技术创新促进地区经济发展；相邻地区产业多样化与创新水平对地区经济发展影响显著为正，表明存在空间依赖效应；进一步将产业多样化划分为相关和无关多样化，发现相关多样化是创新产出的主要原动力，无关多样化的影响效应不显著。%After analyzing the theoretical mechanism among regional industrial diversification,technolog-ical innovation and economic development in China,this paper puts forward the simultaneous equations model. Further the empirical test is implemented based on the Chinese provincial panel data from 2003 to 2011 . The results show that the industrial diversification significantly promotes the regional economic development through technological innovation. The industrial diversification and technological innovation from the adjacent provinces also plays the positive role in the regional economic development,which indicates the presence of spatial de-pendence effect. Further the regional industrial diversification is decomposed into the related and unrelated di-versification. It is found that the related diversification is the main determinant affecting the technological inno-vation,but the effect of unrelated diversification is not significant.
