本文基于2003-2013年中国制造业数据，采用灰色关联理论和距离协同模型对产品和工艺创新协同发展程度进行了总体、东中西分区域以及分省域的比较研究。结果表明，中国制造业总体产品和工艺创新协同发展程度呈现持续提升态势，但产品和工艺创新的发展程度要小于其协同程度；东中西部的区域制造业产品和工艺创新协同发展程度差异显著：东部地区领先，中部地区次之，西部地区最低；各省域制造业产品和工艺创新协同发展程度也存在明显差异，且不均衡。基于上述结论，本文提出了促进中国制造业产品和工艺创新协同发展的相关政策建议。

Based on the data of Chinese manufacturing industry from 2003 to 2013, this paper, by means of grey relational theory and distance collaborative model, makes a comparative study of the product and process innovation synergy development degree from the overall, regional and provincial aspects. The results show that, the overall innovation synergy development degree of Chinese manufacturing industry presents a sustained upward trend, but the development degree of product and process innovation is lower than its coordination degree；the innovation synergy development degree of regional manufacturing industry in eastern, central and western regions is significantly different, among which the eastern region is in the lead, the central region is the second, and the western region is the lowest；and there are also obvious differences of innovation synergy development degree among provincial manufacturing industry. Based on these results, this paper puts forward some relevant policy recommendations for promoting the innovation synergy development of Chinese manufacturing industry.
