公部門知識存量對就業的影響，較私部門知識存量對就業的影響大。此結果支持設立公部門研發中心的政策，改善基礎就業環境與整體國家技術水準，避免只補助單一產業。 This paper attempts to quantify the effects of public sector R&D and private sector R&D on employment of 29 OECD member countries over the period from 1981 to 2009. Apply System GMM to estimate the panel of dynamic employment equations. We find that public sector R&D indeed affect employment positively. So does private sector R&D as indicated by the previous literature.
However, public R&D and private R&D positively affect employment in the current period only. The negative effect on employment of lagged private R&D is significant over the last 2 years, but it converges over time. While the negative effect of lagged public R&D only last one period.
As for the employment effect of R&D stock, public sector reveals greater influence than the private sector. This result supports the policy of establishing public R&D centers, rather than granting R&D resources to a single industry, to improve basic employment environment and national technical standards.
