This paper is a first attempt of looking into the impact of IT and enterprise reform on productivity of Chinese manufacturing firms by using large scale firm level datasets from 1995 to 2002. It is found that enterprise reforms captured by entry and exit of firms have a positive impact on aggregated productivity growth. In addition, IT plays relatively more important role in productivity performance of post reform enterprises, as compared to enterprises which are not affected by major restructuring in the course of Chinese state owned enterprise reforms.
