This chapter，taking the 4 typical industries of electric power，telecommunication，civil aviation and railway as cases，summarizes the experience in reform of regulation over China’s monopoly industries，particularly the infrastructure industries characterized with natural monopoly，and analyzes the problems and shortcomings. The reason to choose the above 4 industries is either due to the fact that they need stronger effort in reform and may produce deeper impact，such as telecommunication and civil aviation，or due to the fact that their reform progress slowly and face contradictions and problems，such as electric power and railway. Although the reform of those 4 industries includes not only reform of regulation，but also reform of property right，but this chapter has to confine to reform of regulation owing to limited space. Moreover，it could only analyze regulation over economic monopoly，not administrative monopoly，because administrative monopoly is an issue which cannot be solved simply through reform of regulation and should not be discussed in the framework of reform of regulation.
