This paper analyzed the influences of industrial structural change upon the productivity growth of China's service industry. As the result, we can see that the average growth of labor productivity of China's service industry is low, compared to that of the manufacturing industry. The growth of labor productivity in the service sector mostly depends on the growth of several particular business types, and is not so much influenced by the change of industrial structure. But, the change of industrial structure influenced the growth of labor productivity positively. It is clear that the increase of the share of service industry would obstruct the labor productivity growth in China.
