Thus, each component's profitability change can be analyzed based on technical efficiency change, scale efficiency change and allocative efficiency change.
Li, H., Zhang, W., Zhang, F., Du, F. & Li, L. Chemical fertilizer use and efficiency change of main grain crops in China (in Chinese).
The study found that the average TFP change is 1.4%, which is mainly due to the efficiency change of 3.3%.
The results suggest that pure technical efficiency change and the scale change of the technology explain most of the productivity growth observed during the period.
In addition to the spectral analysis, differences between two-terminal and three-terminal devices are discussed, showing the light emission efficiency change.
Furthermore, the index of efficiency change (EFFCH) is decomposed into pure efficiency change (PECH) and scale efficiency change (SECH) and therefore follows relationship (6).
The table reveals that the estimated pure efficiency change and scale efficiency change do not affect TFPC (both average scores are equal to 1).
The model applies for panel data and calculates indices of total factor productivity (TFP) change, technological change, technical efficiency change and scale efficiency change.
The growth is generated by the increase in efficiency change (1.77 %) and technological progress (11.83 %).
Germany, Hungary, and Latvia show above-average technical efficiency change scores.
Further decomposition of equation (5) provides measures of efficiency change and technical change separately.
