Abstract: China's speed is changing to the quality of China. High quality development needs to solve the core factors that restrict the high-quality growth of China's total factor productivity. Based on the annual data of 1996-2015 years, we have selected economic system reform, technological progress, opening to the outside world, four first level indexes of infrastructure and 24 two level economic indexes. By establishing factor enhanced vector autoregressive (FAVAR) model, the factors that affect the yield of all factors in China are analyzed to explore the influence. The core elements, the direction of the impact and the contribution of the role. The study found that:(1) In the short run, the common factors of economic system reformation, technology import and open strategy have a more powerful positive impact on the total factor productivity; (2) In the long run, the common factors of independent innovation and infrastructure construction have a persistence positive effect; (3) On the contribution of total factor productivity in our country for nearly 20 years, the biggest factor is economic system reformation, and the following factors are technology import and open strategy, independent innovation and infrastructure construction's contributions are more lower. So, the way to improve the total factor productivity and transform the pattern of economic development is to pay more attention to the developments of independent innovation and infrastructure construction, to release the reformation bonus as soon as possible, to enable the technology import and open strategy play the auxiliary role.

Key words: high quality development, total factor productivity, factors of action, factor-augmented vector autoregressive, independent innovation
