Improving the accuracy of the green total
factor productivity (GTFP) calculation has certain
theoretical and practical value for sustainable development.
We use a slack-based directional distance
function (DDF) proposed by Färe and Grosskopf
(European Journal of Operational Research 200:320-
322, Färe and Grosskopf, European Journal of Operational
Research 200:320–322, 2010) to combine with
Malmquist-Luenberger Productivity Index (MLPI) to
re-examine the GTFP. This new GTFP index takes
inputs such as energy consumption, labor, and capital
stock into account, while considering the comprehensive
outputs of real GDP and three types of industrial
wastes (gas, solid, water). The proposed slack-basedMLPI is applied to access GTFP changes and compare
the results under the slack-based DDF measure
and original DDF measure over the period 2005–
2012. The primary results in this paper present the
average growth of GTFP for these 30 Chinese provinces
shows a downward trend until 2010 suggesting
that most provinces pay less attention on the productivity
growth. The downward trend results primarily
from no significant improvement in technical change.
We also discover that although the distributions of the
slack-based measure are roughly similar with that of
the original DDF, the decomposed component, efficiency change, shows a significant difference between them.
