Abstract: The education of Library Information and Archive Management in Chinese Mainland has developed rapidly. With the saturation of the traditional job market and changes in the industry, graduates’ career directions have gradually shifted from traditional library and archive institutions to information service institutions in a broad sense, medical institutions, state-owned enterprises, and civilian positions in military. Adopting a quantitative research method based on a manually constructed multidimensional corpus of " LIS Jobs", and coupled with Named Entity Recognition and Social Network Analysis, we conducted an empirical research on the labor market of public positions in LIS field. The study found that the number of institutions and employees in LIS field have been increasing, and public institutions and civil servants are the main sources of demand; that public institutions show a trend of shift from traditional LIS positions to new emerging positions; that MLIS education and LIS doctoral education have become the main sources of LIS migration to industry and building academic influence; that the geographical imbalance in LIS job distribution is still prominent; and that LIS majors face greater external competition in the labor market. Finally, we provided advice for various interest groups including graduates, universities and the government.
