Scientific and technological progress is an important means to promote economic development, and scientific and technological progress is inseparable from the cultivation of talents. During graduate study, students need to balance different factors such as learning, scientific research and employment skills training. Industry can provide support to university research institutes: first, from the perspective of reciprocity, graduates with relevant professional skills can be absorbed into industrial research to improve the technical content and added value of enterprise products; On the other hand, industry can reduce the employment pressure of students, first of all, it plays an auxiliary role in their scientific research during school, and can promote the overall scientific research level of society by absorbing high-tech talents into enterprises and developing new technologies.

The cultivation of talents is the embodiment of a country's core competitiveness. Schultz said that the investment of human capital plays a great role in the country's economic development. After World War II, the economy of many developed countries was rapidly rebuilt from the destroyed buildings, factories and other adverse conditions, which is closely related to the factors of human capital [1]. In contrast, Japanese companies bought large American buildings in the 80 and 90s of last century, but did not get much praiseworthy technology or talent, so after the economic bubble burst, it was difficult to recover the economy in the short term. Fortunately, Sinochem's acquisition of Syngenta and Geely's acquisition of Volvo cars and other commercial activities have obtained advanced technologies and patents in these industries. Even though some technologies may not be imported due to regulation, they can integrate talents, technology and management through overseas employee training to improve competitiveness. With China's economic development, it has accumulated a lot of funds that can be invested in talent training. For example, the foreign exchange reserve of US $3 trillion is enough to pay the tuition for training 100 million master students (for example, the tuition for master students in the United States is about US $40000, the tuition for master students in the United Kingdom is about US $20000-30000, and the tuition for master students in Germany is free). The current trend of graduate enrollment expansion reflects the society's attention to human capital and talent training.

From the perspective of graduate students, the vast majority of people need to enter social work after graduation, rather than stay in Colleges and universities to engage in teaching and research activities. Suppose that a professor has trained about 30 master's and doctoral students for more than 30 years, and only one position will be created after he retires. It is estimated that with such a rapid change of teaching posts, at least 90% of graduate students cannot enter academia after graduation and need to find jobs in industry. Doctoral students with scientific research talent and good luck can work hard in the academic community, insist on looking up at the stars and exploring the unknown world. However, most students should be psychologically prepared, cultivate skills to connect with industry, solve problems or needs in real society, and find suitable jobs. For the society, it is not necessarily a bad thing if employees in the express industry and agriculture have graduate degrees. It may indicate that the society has developed to a very high stage, with a high level of education per capita and a high human development index. For graduate students, after entering the society, they may look forward to a job that can give full play to their talents.

After graduation, the first problem faced by graduates looking for jobs in industry is the problem of assessment and selection. Some enterprises attach too much importance to the first undergraduate degree of postgraduates, but the first degree only reflects the college entrance examination results, but does not measure the performance in the University, nor does it reflect the efforts and efforts of postgraduates. On the one hand, the investigation scope of the college entrance examination and the skills needed for work vary greatly; On the other hand, learning at the University and graduate level depends more on students' dedication and self-discipline. Without the urging of teachers and parents, it is a quality more worthy of pursuit. For masters and doctors, the assessment method of recruitment enterprises should not be a simple written test or Brainteaser similar to the entrance examination. Otherwise, it is equivalent to admitting to a certain extent that the skills paid and cultivated by students after several years of hard postgraduate study are meaningless in the eyes of recruitment enterprises.

From the perspective of recruitment enterprises, it is really difficult to measure and evaluate graduate students. It is relatively simple to recruit college students. After the preliminary screening of resumes, through a single blind experiment, cover the name of the graduated university in the follow-up assessment to reduce the impact of the college entrance examination results, and conduct a unified written test and interview for consideration. However, the background and research direction of graduate students are also different. Because of the subdivided professional content of three or five years of research experience, it is often difficult for interviewers to understand and ask pertinent questions. Scientific research achievements are not like singing competitions, which are suitable for young and old. It is difficult to measure different students with a common yardstick. Therefore, if the enterprise does not pass the quantitative form such as examination, it may be criticized because the selection criteria are opaque.

We need to adopt a variety of ways to more organically combine graduate employment and enterprise recruitment to promote mutual understanding and cognition. From the perspective of postgraduates, internships in enterprises are very helpful for future employment. It is a better way to choose from each other by dealing with practical problems at work and communicating with other colleagues: whether the company culture is suitable for themselves and whether postgraduates adapt to the company. Postgraduates need to consider the time point suitable for internship. A common concern is that a long-term interruption does not guarantee a smooth return of scientific research [2]. Some guidance professors worry that in some rapidly developing fields, the internship of Postgraduates may lead to the rush of papers, or the students' good income during the internship may affect the mentality and focus when scientific research returns. The more suitable time point for internship may be the summer vacation before graduate students enter school, the vacation after teaching but not full-time scientific research, and the transition stage of master's degree to doctoral degree. The experience in the internship may also enable students to focus more on solving problems and cultivate their ability of project management and time management, or transfer to self-management in scientific research activities, and get along with their tutors more harmoniously.

The matching between a wider range of graduate students and enterprises can adopt a model similar to the combination of ball game draft and academic conference. In academic conferences, there are usually booths of recruitment enterprises to accept the resumes of graduate students, but this model is passive, because recruiters only sit behind the booths and do not actively understand the research results of students. A more appropriate display should be that graduate students from different colleges and departments of the university will organize their own one or two-day symposium, invite R & D personnel from relevant departments of enterprises with recruitment intention to participate in the seminar, and display the research results of students about to be employed through the academic report of the seminar [3]. In the previous article, we mentioned the need to actively look for problems and needs in the real world and design good solutions; It is also necessary to introduce the advanced technology of the school to the industry. "In fact, many or most of the inventions were made by curious people or people who like to tinker with them. At the beginning, there was no need for the products they thought of." [4] academic reports held by different departments of the university can graft the understanding of advanced research results between academia and Industry, At the same time, it also looks for good professional counterpart enterprises for postgraduates. The performance of players in the basketball and football matches of the National Collegiate Athletic Association (NCAA) can be used as a reference for the draft of professional leagues, as can the display of scientific research achievements of universities. The volunteers of the graduate Association have developed the ability to contact and organize activities; The graduate students at the report meeting also need to cultivate their oral expression ability (students also need good expression and communication ability at work) and show their research results in detail.

Developing countries urgently need R & D talents in basic and application fields. There are many Indian executives in high-tech enterprises in the United States, but India itself has not produced such high-tech enterprises. C-suite level talents have high mobility all over the world. To some extent, this comparison shows the differences between India and the United States in grass-roots, middle and high-level talents (of course, various factors such as entrepreneurial environment). The vocational training of postgraduates is not necessarily only engaged in R & D. high value-added technology enterprises also need more managers who understand technology, and the expansion of Postgraduates lays a certain foundation for such talent training.

Breakthroughs in scientific research are accidental, similar to the crystallization process of supersaturated solution. It is impossible to accurately predict when and where to crystallize. Even investing a lot of money in a hot field does not guarantee the output of excellent research results. But this does not mean that people should give up their efforts and choose to take a chance. Society can provide an environment similar to supersaturated solution, encourage the discussion and competition of different academic ideas, and encourage and pay attention to talents. When the number of talents is large enough, quantitative change will lead to qualitative change, so as to crystallize the breakthrough of scientific research. Although we can't predict where the sprout of the next technology explosion will appear, the sprout will certainly appear when spring comes. A graduate student who works very hard may still not get the expected scientific research progress due to factors such as luck, but this adventurous spirit promotes the progress and development of society. The society needs to encourage and praise this adventurous spirit of scientific research, and the industry can also better absorb the employment of R & D personnel, reduce students' worries, make students more focused, breed better innovative talents and build a better innovation environment.
