As can be seen from the empirical results of the Table 5, all groups of hospitals achieved statistically significant (at the 5% level) increases in productivity between 2009 and 2013 with the exception of group B that is shown to exhibit a (non-statistically significant) slight decrease. It is interesting to note that the larger hospital set (group D) is shown to exhibit the greater (statistically significant) productivity change by 26.8%. However, when the total productivity change is decomposed into efficiency and technical change, it appears clearly that the growth in productivity is primarily attributed (20.2%) to a progressive shift of the efficient frontier and secondarily (5.5%) to efficiency improvement. The results indicate that the dominance of the technology versus efficiency change is reversed for the other groups of hospitals. Specifically, in groups A and B, the contribution of efficiency change in productivity is positive by 11.8% whilst the corresponding contribution of the technology change component is negative by 2.1% and 11.1% respectively. Similarly, the statistically significant productivity improvement by 7.1% in group C is mainly due to efficiency improvement (4.7%) rather than to technology progress (2.4%).
