Innovation, internationalisation and the performance of microbusinesses
研究了英国微型企业（员工少于10人）中创新如何通过促进出口活动间接提升生产率，而非直接提高生产率。
This article integrates internationalisation, and specifically exporting, into a conceptualisation of how innovation production leads to productivity performance in microbusinesses employing fewer than 10 people. Innovation production is reframed for the microbusiness context by focusing on knowledge acquisition and formalisation rather than on research and development (R&D) activity. Propensity score matching analysis is used to investigate British microbusiness survey data. It finds a causal process in which innovation promotes exporting activity. This in turn leads to improved productivity. In contrast to research on larger businesses, this study finds no direct link between innovation production and productivity. These findings are robust to various checks for potential endogeneity arising from feedback into innovation from internationalisation and from self-selection of high productivity firms into exporting.
