According to related theories of Spatial Econometrics , we apply MM Extreme Bounds Analysis model to analyze robust factors of regional disparities on China's R&D location distribution , based on the panel data of 30 provinces in China (except Tibet) . The results show that R&D intensity and its determinants are different in the east , the middle and the west areas . In east areas of higher R&D intensity , the “robustness” factors are the technological level , market scale , fixed asset investment and factor endowment . In the middle areas of moderate R&D intensity , the determinants are the governmental public policy , technological level and factor endowment . In west regions of lower R&D intensity , technological innovation and factor endowment have significant influence on improving the R&D intensity . The above analysis reveals the laws of development and disparities of R&D intensity . We conclude by providing some corresponding policy suggestions as theoretical and practical basis for different areas .%依据空间计量经济学的相关理论，运用稳健MM估计的EBA （异常值检验的极值边界分析）模型，采用中国30个省际区域2002～2012年的面板数据，实证研究中国东部、中部、西部地区R&D强度区位分布条件的“稳健性（Robust ）”影响因素。结果表明：我国东部、中部、西部各地区的R&D强度存在差异，且其影响因素也不尽相同。R&D强度较高的东部地区，科技水平、市场规模、固定资产投资、要素禀赋等4个因素对中国R&D强度具有抗干扰的“稳健性”影响；R&D强度中等的中部地区，3个“稳健性”影响因素是政府公共政策、科技水平和要素禀赋；而对于R&D强度较低的西部地区，技术创新和要素禀赋对提高R&D强度作用具有“稳健性”。由此揭示我国R&D强度的发展规律以及各区域间的差异性，并根据实证结论提出一些政策建议，为各地区制定科技政策目标和实施方案提供经验证据和决策参考。
