The mechanism analysis of service structure change affecting employment is the main part of the thesis. The mechanism is Under the condition, the organic connection mode, the action form, the structure function formed between each part of the thing, the most important is its the process of interaction and the inherent operation law thus embodied. In the process of economic development, due to demand structure, supply To the structural and technological progress and other factors, leading to the evolution and upgrading of industrial structure, resulting in changes in labor employment, The transformation of employment structure and the change and interaction of industrial structure have certain regularity. Process of internal structural changes in services With the optimization of the service industry structure, the internal structure of the service industry changes due to the turnover of the leading industrial sector, which is manifested as The development of the dominant mechanism industry which affects employment in the service industry itself needs to absorb labor force and thus drive employment. Only It is obviously not enough to analyze the absorption effect of service industry itself on employment explicit employment mechanism because, service industry and other industries There are various kinds of interaction, the development of service industry can promote the development of other industries, and then promote employment, this is service The hidden mechanism that the change of service structure affects employment is restricted by the multiplier effect, industry wave and effect of economic development should, labor supply and demand pairing effect, innovation effect and improve the livelihood effect. In addition, attention should be paid to technological progress The effects of technological progress on employment have both reduced employment in traditional jobs and increased employment Effect. The technological progress brought about by modern service industry and its compensation effect on employment are mainly stimulated in two ways The second is to stimulate the new investment needs of producers to promote employment. Employment In the whole system, the development of service industry is closely related to the expansion of employment. It is precisely Because of the existence of the mechanism of action, it shows the inevitable trend of vigorous development of service industry and expanding employment.
