摘要:AbstractThe purpose of this study is to measure and compare the performance of the National Innovation Systems using the information available in IUS 2011 database. In order to fulfill this purpose, the variables describing the innovation process included in this database are used to estimate the technical efficiency of the EU27 Member States as well as Croatia, Iceland, Norway, Switzerland and Turkey.Thus the efficiency of the decision making units represented by National Innovation Systems is estimated using a nonparametri c frontier model: data envelopment analysis (DEA). Statistical inference for DEA estimators is based on bootstrap, a very well- known resampling method. Ranking the countries provide an interesting insight into the innovation system classification.
