Economic situation in China has entered into a new normal stage, and it is necessary to strengthen scientific and techn-ological innovation, realize system innovation, and improve the total factor productivity in order to realize economic sustainable develo-pment. Some data is measured in 30 provinces' total factor productivity from 1998-2012 , using DEA-Malmquist index method. We also researched the change trend, stage characteristics, regional difference and influencing factors. We found that the average growth rate in China from 1998-2012 is 0.1 percent, that improvement of technical level caused the growth. There is big difference of total factor productivity in the provincial level. The consequences show a certain convergence in area level. There were no changes in total factor productivity growth rate in eastern and western areas. The technical level in these areas increases by 0.3%, but the technical efficiency decreased by 0.2% and 0.4% respectively. Central parts' growth rate of total factor productivity is 0.3%, caused by the improvement of technical level. Besides, we also found that the total factor productivity is strong inertia, advanced industrial structure and the improve-ment of external dependency will help to improve the total factor productivity.%中国经济进入新常态后，需加大科技创新力度，实现制度创新，提高全要素生产率以实现经济可持续发展。文章采用DEA-Malmquist指数方法对我国30个省份1998-2012年全要素生产率进行了测度并考察全要素生产率变化趋势、阶段特点、区域差异和影响因素。研究发现：全国1998-2012年全要素生产率平均增长率为0.1%，增长来源主要是技术水平的提高；全要素生产率省际差异较大，而区域表现出一定的趋同。1998-2012年间，东部地区和西部地区全要素生产率增长率无变化，两个地区虽技术水平变化增长0.3%，但技术效率分别下降0.2%和0.4%；中部地区全要素生产率增长率为0.3%，增长主要得益于技术水平的提高；全要素生产率存在较强惯性，产业结构高级化和对外依存度的提高均有助于提高全要素生产率。
