“…Besides the national-level data, provincial statistics of China have also been extensively used to investigate regional disparity of productivity growth and patterns of technical efficiency in Chinese agriculture. These researches include the early works, see, e.g., Mao and Koo (1997), Lambert and Parker (1998) and Wu et al (2001), which measured China's regional agricultural productivity change and its components in terms of technical change and efficiency change mainly based on the nonparametric DEA approach and Malmquist Index, and the recent studies, see, e.g., Wang and Rungsuriyawiboon (2010), Ito (2010), Zhang and Brümmer (2011), Ma and Feng (2013), Zhou and Zhang (2013), which identified the sources of China's agricultural productivity change mostly by using the parametric methodology (viz., SFA) assuming Cobb-Douglas, separated Cobb-Douglas or translog production function, and meta-frontier approach. Nonetheless, despite the differences in research methodologies and periods covered in the aforementioned literature, the conclusions drawn in these papers are almost consistent, indicating that: (1) China has experienced an impressive improvement in agricultural TFP, which was mainly driven by technical progress (namely the outward movement of the production frontier), while efficiency change (namely the proximity to the production frontier) has acted against the improvement in TFP in most of the periods; (2) there have been significant regional disparities in productivity performance due to the differences in both technological innovations and efficiency enhancements.…”
