[Purpose/significance] Through the analysis of researchers' demand of electronic resources in the electronic environment, we want to provide data support and scientific references to formulate the development strategy of the electronic resources from the perspective of the library users.[Method/process] We used the questionnaire survey method to analyze the researchers' demand of electronic resources in the electronic environment, including the use situation, the use preference and influence factors, expectation and suggestions, etc.[Result/conclusion] We have three findings. Firstly,the current scientific research is very dependent on electronic resources and there are many new characteristics in using electronic resources, including complying with the 80/20 Rule, using many channels, relying on commercial search engines, attaching importance to the open access resources and resource sharing services, etc. Secondly, the researchers' use preference is affected by the type of the researchers, the types of resources and the electronic resources' advantages and disadvantages. Thirdly, the researchers have cautious optimism about the advent of the "pure electronic" era, but almost all of them believe that the electronic resource development will disruptively change and influence the library industry. The survey has the sample data of high quality, the survey process has been strictly controlled, and the data processing and analysis have been implemented scientifically. Therefore, the results of the survey are considered to be authentic.
