Abstract: After entering WTO, China's intellectual property protection legislation is already quite complete, the actual level of intellectual property protection in China mainly depends on the level of law enforcement. Measurement for the level of law enforcement of intellectual property rights protection has involved multiple levels and departments. It is complex and more difficult to measure. This paper will construct the law enforcement level index system of China's intellectual property protection. The index system involves all aspects of society and the relevant law enforcement departments. It covers the main types of intellectual property and tries to choose the index which can reflect directly the actual level of law enforcement. This paper uses the index system to measure and analyze the level of law enforcement of the Intellectual Property Protection in China from 2001 to 2012.
