| Summary/Abstract |
Since 1980s, China has experienced a series of reforms to support the development of electricity industry, and the latest one is in 2015. The essence of this new reform is to improve efficiency and lower energy cost. However, China's electricity market has its particularity. The “provinces as entities” is the main regulation frame in China's electricity sector. The operation of the electricity industry can be seen as a game result and interest compromise between the local government and grid companies, and this “win-win exchange” regulation failure leads to grid market power. The profit mode of the grid enterprises will be gradually changed with the deepening of new electricity reform. How to regulate electricity transmission and distribution sector and improve grid efficiency becomes a crucial problem to address. This paper aims to examine the relationship between market power and power grid efficiency. We calculate the unconditional and conditional efficiency of grid companies by applying a conditional slack-based measure (SBM) model. The empirical results show that grid efficiency is at a low level and the indicators differ among provinces and regions. Moreover, market power indeed has significant negative effects on power grid efficiency. These findings provide some insightful references for the future development of China's power industry and electricity reform.

| Summary/Abstract |
In order to overcome the perverse incentives of excessive maintenance reductions and insufficient network investments arising with incentive regulation of electricity distribution companies, regulators throughout Europe have started regulating service quality. In this paper, we explore the impact of incorporating customers' willingness-to-pay for service quality in benchmarking models on cost efficiency of distribution networks. Therefore, we examine the case of Norway, which features this approach to service quality regulation. We use the data envelopment analysis technique to analyse the effectiveness of such regulatory instruments. Moreover, we discuss the extent to which this indirect regulatory instrument motivates a socially desired service quality level. The results indicate that internalising external or social cost of service quality does not seem to have played an important role in improving cost efficiency in Norwegian distribution utilities.
