influencing factors of research efficiency, it’s required to rule out those indicators
being used in thefirst stage DEA computations like number of teaching & research
Staff. Second, when using panel data to examine the influencing factors of uni-
versity research efficiency in 2006–2010, the long duration of time period would
lead to the missing values on some indicators, thus we have to rule out those
indicators which cannot cover the whole period. Third, in the computation of DEA
efficiency scores, we run the models for NEAM and HSS samples separately, thus
theoretically it would be better if we use separate indicator systems at the second
stage. However, some environmental factors are equal to NEAM and HSS disci-
plines, plus the difficulty of distinguishing the data of sectoral and institutional
factors and internal factors, we have no choice but to apply the same indicator
system to both NEAM and HSS. Thefinally selected indicators are presented in
Table6.2.
6.2.1.3 Descriptive Statistics of Explanatory Variables
Table6.3presents the distribution of 211Us. In thefirst stage of econometric
analysis, we need to estimate the DEA efficiency scores of NEAM and HSS dis-
ciplines separately. As we mentioned in previous chapters, the NEAM sample and
HSS sample are slightly different. We have 100 cases in the NEAM sample and 105
cases in the HSS sample.
Table6.4 presents the annually average of each indicator concerning the
influencing factors of 211Us research efficiency, as well as research efficiency
score, in each year of 2006–2010.
First, we analyze the annually average of efficiency score. To NEAM disciplines,
the annually average of efficiency scores are all around 0.8 over the period, without
