Productivity is of vital importance to the sustainable development of an enterprise. Based on Chinese firm-level production data and transaction-level data from 2000 to 2006, we use the international forefront ACF approach to calculate the enterprises productivity. Referring to Gervais (2013) and Shi Bingzhan (2015), we calculate total factor productivity, and employ GPSM method to study the impact of imported intermediate products on enterprises productivity. The results show that there is a “U-shaped” relationship between the quality of imported intermediate products and the productivity of enterprises. The “U-shaped” relationship was still established when the OP/LP method is used to test enterprise productivity.
