Abstract
Green innovation is an important capability for an enterprise’s sustainable development. Evaluating the green innovation efficiency of China’s industrial enterprises can greatly affect its improvement. Considering the existing research results of green innovation efficiency evaluation, this paper added the impact of environmental factors in the technology industrialization stage. Various negative environmental externality indicators produced by industrial enterprise activities were incorporated into the undesired output, and an index system and model were constructed for evaluating the green innovation efficiency of China’s industrial enterprises. Combined with the actual data, a three-stage chain network SBM (slack-based measure) model was used to dynamically evaluate and analyze the industrial enterprises in 29 Chinese provinces. The results show that the overall efficiency of green innovation in China’s industrial enterprises has an upward trend, and the rise fluctuates during the technological development, achievement transformation, and industrialization stages. In the three major regions of China, industrial enterprises in the eastern area have the highest green innovation efficiency, and the industrial enterprises in the west and central regions have lower efficiencies. Based on the evaluation results, the corresponding countermeasures are proposed.
Highlights
Resource conservation and environmental protection are regarded as national policies in China. e 19th National Congress report clearly stated that people and nature should harmoniously coexist and the development principle of “lucid waters and lush mountains are invaluable assets” is to be implemented
During the ten-year period 2008 to 2017, the green innovation efficiency of China’s industrial enterprises generally showed an upward trend, with the green innovation efficiency of the technological development, achievement transformation, and industrialization stages rising among twists and turns
E results show that the efficiency of the scientific and technological innovation stage is 0.7150 and the efficiency of the achievement transformation stage is 0.7283, both of which are higher than the industrialization stage, which is 0.4890
Summary
Resource conservation and environmental protection are regarded as national policies in China. e 19th National Congress report clearly stated that people and nature should harmoniously coexist and the development principle of “lucid waters and lush mountains are invaluable assets” is to be implemented. Resource conservation and environmental protection are regarded as national policies in China. E “Kyoto Protocol” and “Paris Agreement” aim to control the total greenhouse gas amounts and degree of global warming. In this context, green innovation is gradually gaining importance. Does green technological innovation respond to the national calls for energy saving and emission reduction and fulfill the social responsibilities of enterprises, but it provides more services for enhancing enterprise competitiveness. The essence of green technological innovation is to implement the national environmental protection policy, eliminate backward production facilities, realize industrial structure upgrade, and enhance the requirements for increasing national industrial strength. Related studies rarely use nonradial models to calculate green innovation efficiency and generally regard the efficiency process within DEA as a “black box,” internal structure within the innovation process is ignored [2]
