英文摘要：

Based on the context of a transition economy, this paper uses the data of Chinese industrial enterprises to examine the impact of ownership concentration on innovation. It analyzes the innovation and financial performance by comparing among state-owned enterprises （SOEs）, privately-owned enterprises （POEs） and foreign-invested enterprises （FIEs） . It is found that concentrated ownership negatively associated with both R＆D input and innovation output. SOEs are positively related to innovation input, while SOEs have disadvantages at innovation output comparing with FIEs. Additionally, SOEs and POEs put more stress on performance comparing with FIEs.
