Nearing the end of the 20th century, countries across the world have gradually been going into depression, without exception, this effect has also influenced Taiwan. Moreover, with the coming of age of knowledge management and change of the industry structure of the 21st century, thus the industry structure in Taiwan has also gone through some changes, adding many new non-typical jobs into the job market. Some examples include Leased Employess, Telex of Labor, part-time work, multiple job holders. Previous study on part-time work has been focused on the characteristics of the part-time workers and the influence on female part-time workers¡¦ employment and the reasons why companies use part-time work. Less research has been made on the comparison between part-time workers and regular workers. In the Human Resources of Managenment survey made by the Minster of Affairs in1997, the content regarding multiple job holders describes the distribution situation of multiple job holders. Moreover, with the fast growth of knowledge management, there exists a non-equivalency between the structure of knowledge management and the need of such a structure. Does the increasing numbers of part-time workers and multiple job holders mean that the labor market will take on a more important role? What is the difference between the education level, occupations, industry and income of these workers and regular workers? After a comparison between these two, which gains more profit? These are the questions to be answered in this research. The statistical information used in this research is secondary information from Directorate General of Budget Accounting and Statistics Executive Yuan, R.O.C regarding the Taiwan region Human Resources of Managenment statistical information, which divides labor into three groups, using work time and income level as a basis to find the characteristics between these three groups. Some implications made from the result of this research has been made for reference for the government. The results of this research are as the following: Part-time work 1¡BHighly educated part-time work are more better off than low educated part-time work because they have relatively higher pay for lesser work. 2¡BThe part-time workers of the higher level labor market are better off than the those from the agricultural, forest, fish and pasture and manufacturing. 3¡BThere is an increase of the laborers in the service sector, and a decrease of those from the agricultural, forest, fish and pasture sector, not much change in the manufacturing and industry sector. 4¡BFrom a comparison of the income of these sectors, those in industry have the highest income, and those in services are second ranking, from the level manufacturing gains the most and industry the least. Multiple job workers 1¡BThese are the least luckiest of the group because they have the highest work hours, but have the same income level as normal workers 2¡BNo matter which profession, multiple job workers are the most laborious because they have more work hours than normal workers but less income than normal workers. 3¡BNo matter which industry, multiple job workers are the most laborious because they have more work hours than normal workers but less income than normal workers. 4¡BThere is an increase of the laborers in the service sector, and a decrease of those from the agricultural, forest, fish and pasture sector, not much change in the manufacturing and industry sector. From a comparison of the income of these sectors, those in manufacturing have the highest income, and those in industry are second ranking, from the level manufacturing gains the most and services the least.
