Evaluating R&D efficiency of China’s listed lithium battery enterprises

Frontiers of Engineering Management Pages 473-485 doi: 10.1007/s42524-022-0213-5

Abstract: Results revealed little indication of a meaningful improvement in R&D efficiency throughout our samplewas 0.442, whereas the average pure technical efficiency was at 0.503, thus suggesting that they weresuffering from decreasing returns to scale (DRS).Moreover, they were experiencing increasing scale efficiency (IRS).that supporting technologically intensive sectors should be more than simply increasing investment scale
