International exchanges of knowledge, temporary skilled labour movements, and Australia's economic growth

众所周知，熟练劳动力是经济增长的重要来源，因为它创造了新的知识和创新，澳大利亚与其他国家一样，利用政策吸引技术移民。然而，鲜为人知的是，数以千计的熟练工人也会临时移民，通常是为了交流知识。虽然对永久移徙的影响进行了广泛的研究，但本项目将研究短期劳工流动的经济影响。该项目将利用DIMIA的数据和对临时移民的调查，分析临时劳动力流动对澳大利亚创新能力、生产率和经济增长的影响，为制定移民政策做出贡献。

It is known that skilled labour is a significant source of economic growth as it creates new knowledge and innovation, and that Australia, like other countries, uses policies to attract skilled migrants. It is less known however that thousands of skilled workers also migrate temporarily, often to exchange knowledge. Whilst the effect of permanent migration is widely researched, this project will examine the economic impact of short-term labour movements. Using data from DIMIA and surveying temporary migrants, this project will analyse the consequences of temporary labour movements on Australia's innovation ability, productivity and economic growth, contributing to develop migration policy.
