1. Different purposes: The main purpose of graduation thesis is to master scientific research methods and skills and improve one's scientific research ability through in-depth research on a certain topic; The main purpose of the opening report is to introduce the research direction, problems, objectives, methods and other contents of the paper to the tutor and the evaluation Committee before opening the topic, and to solicit opinions and suggestions.

2. Different contents: the graduation thesis includes abstract, introduction, literature review, research methods, experimental results, discussion and analysis, conclusions and other parts, which require in-depth research on a certain topic; The contents of the opening report include research direction, background, objectives, significance, methods, data sources and analysis. And it is necessary to introduce the research plan of the thesis to the tutor and the review Committee.

3. Different research progress: the graduation thesis is based on the opening report for in-depth research and exploration, and finally forms a complete thesis, which needs to be completed within the specified time; The opening report is a research plan to report the paper to the tutor and the review committee after determining the basic elements such as the direction, problems and objectives of the paper, which can be modified and improved through the opinions and suggestions of the tutor and the review committee.

4. Different forms of defense: graduation thesis needs to be defended, and oral defense is needed in front of academic committees, tutors and evaluation experts to answer related questions; You don't need to answer the opening report, just report the research plan and solicit opinions.

5. The depth of research is different: the graduation thesis needs in-depth exploration and research on research issues, and needs its own independent thinking and innovation; The opening report only needs to put forward the preliminary research plan and direction, and does not need in-depth discussion and research.

6. Different time arrangements: the graduation thesis needs to be completed within the specified time, including topic selection, topic opening, mid-term inspection, thesis writing, defense and other links; The opening report is only the beginning of the paper research, and the time arrangement is relatively flexible.

7. Different requirements for results: the graduation thesis requires graduate students to independently complete certain research work and achieve certain results, such as publishing papers and obtaining patents; The opening report is only a starting point of the thesis research, and it does not need to obtain certain research results.

In a word, graduation thesis and opening report are two important documents in postgraduate stage, and there are obvious differences between them. Understanding the differences between them can help graduate students to do academic research and thesis writing better, so as to obtain better research results.
