1. Get information: exclusive interviews with newspapers, industry websites, documents, magazines, radio and television.

2. Survey method: (1) interview survey method; (2) telephone interview; (3) Questionnaire survey.

3. Observation method: through holding meetings, in-depth field visits, participating in production and operation, field sampling, field observation and accurate records (including surveying and mapping, audio recording, video recording, taking photos, taking notes, etc.). ) survey. It mainly includes two aspects: one is the observation of human behavior, and the other is the observation of objective things. Observation method is widely used, and it is often used in combination with inquiring and collecting objects to improve the reliability of collecting information.

4. Experimental method: In the computer network environment, information or conclusions are obtained through laboratory experiments, field experiments, computer simulation experiments and man-machine combination experiments. We can actively control the experimental conditions, including appropriate restrictions on the types of subjects, appropriate restrictions on information generation conditions and reasonable design of information generation process, and obtain important and effective information that can objectively reflect the motion characteristics of things. To some extent, we can directly observe and study the relationship between some parameters, which is conducive to the study of the nature of things.

5. Internet information collection method: all kinds of information published, transmitted and stored through computer networks. The ultimate goal of Internet information collection is to provide users with network information resources services. The whole process includes four steps: network information search, integration, preservation and service.

In order to ensure the quality of information collection, we should follow several principles:

1. Accuracy: The collected information must be true and reliable, which is the most basic principle. Therefore, collectors should repeatedly verify and constantly test the collected information.

2. Comprehensiveness: Only by collecting information comprehensively and extensively can we fully reflect the whole picture of the respondents and ensure the scientific decision-making.

3. Timeliness: The utilization value of information depends on whether the information can be provided in time. Only when the information is provided to its users in time and quickly can it play an effective role.
