and the change of 211Us’research productivity? Does the improvement of research
productivity mainly come from technical progress or efficiency change? What about
the differences between 985Us and non-985Us? What about the differences
between 211Us located in eastern, central and western regions in China? What
about the differences between 211Us located in Jing-Jin-Ji areas, Hu-Su-Zhe areas
and other areas inside eastern China? We believe that, through answering these
questions we can provide valuable information to the planning and decision-making
of research production in the future.
This chapter is organized as below. Thefirst section gives a dynamic evaluation
on the research productivity of NEAM disciplines and HSS disciplines in 211Us
respectively, and then do the attribution analysis. The second section makes
comparison on the research productivity change between 985Us and non-985Us.
The third section follows this pattern and makes comparison between 211Us
located in different regions. The last section comes with some overview of results
and discussions.
5.1 Change of Research Productivity in 211Us..................
In this section, we compute research productivity index of every 211Us in 2006–
2010 in NEAM disciplines and HSS disciplines separately. MPI has some quality
properties as it can be decomposed into Technical Change (TC) index and
Technical Efficiency Change (TEC) index. TC reflects the production frontier
movement at the two periods and thus being named as“frontier movement effect”
or“growth effect”, which can be used to measure if the technical change exists in
the second period. If TC is larger than one, it visually presents that the technique
advances, and the production frontier moves upward. TEC index measures the
relative efficiency change of production units at the two periods. Furthermore, TEC
index can be further decomposed into Pure Technical Efficiency Change (PTEC)
index and Scale Efficiency Change (SEC) index. PTEC reflects that the change of
relative production efficiency at two periods under the given technique and scale,
which is named“catch-up effect”. If PTEC is larger than one, it means that in the
condition of no technical innovation and scale change, the production of DMU in
the second period gets closer to the production frontier with higher relative effi-
ciency due to better management. SEC index reflects the change of DMU’s returns
to scale at two periods, and measures if the scale efficiency of DMU improves,
which is thus called“scale effect”. If SEC is larger than one, it means that in the
second period, the DMU changes its inputs and improves its scale efficiency. Since
we use panel data of 211Us in our analysis, the detailed research productivity index
