T his paper describes an innovative value chain including know ledge innovation stage and product innovation stage .First ,the paper estimates innovation efficiency using data envelopment analysis .The value chain spillover and spa‐tial spillover are integrated into the same innovation analysis framework .And using spatial econometric model to analyze multidimensional spillover effects of innovation efficiency in following four resigons :yangtse river delta ,Beijing -Tianjin-Hebei ,five provinces of middle China and seven provinces of w estern .Innovation efficiency betw een different stages of the innovation value chain have positive spillover effects .And the stronger is the innovation vitality ,the more significant is the spillover effects .Knowledge innovation efficiency and product innovation efficiency both have significant spatial spill‐over effect .The degree of influence is growing from west to east .Otherwise ,stimulating the vitality of the regional mar‐ket ,enriching the connotation of innovation networks are universal in different areas .In order to establish innovation eco‐system and improve innovation efficiency ,we should take up measures from internal and external innovation ecosystems . Internal innovation ecosystem ,opening up channels of cooperation and improving the innovative service platform are neces‐sary .External the innovation ecosystem ,we have to determine a reasonable system boundary and adopt difference policy .%从创新生态系统视角出发，刻画了知识、产品二阶段创新价值链，利用数据包络分析方法测量了创新效率，将创新效率的价值链溢出、空间溢出纳入统一分析框架。以长三角、京津冀、中部五省、西部七省区市4个区域为研究对象，采用空间计量方法进行了实证分析。结果显示，创新价值链不同阶段创新效率之间存在正向溢出效应，且区域创新活力越强，价值链溢出效应越明显；知识、产品创新效率存在显著的空间溢出效应，且影响程度由西向东呈递增态势；激发区域市场活力、丰富创新网络内涵在不同区域具有普适性。对此，要构建创新生态系统，提高创新效率，一方面应在系统内部打通创新合作渠道，完善创新服务平台；另一方面要确定合理的系统边界，实施差别化创新政策。
