広西壮族自治区における工業企業の効率性と生産性の計測

抄録

China's economic growth is supported mainly by the growth of its industrial sector. Thus, the growth of the industrial sector is an important issue in Guangxi, which is still underdeveloped.
This paper measures efficiency and productivity of the industrial sector of Guangxi since 1995 using firm-level data. Despite various limitations, two kinds of input and output data are available, and efficiency is evaluated using the Data Envelopment Analysis (DEA). The calculated results show that the average efficiency value of Guangxi firms is less than 0.5 on the whole. This suggests that there are very large relatively inefficient firms. Also, change of the Malmquist productivity index does not show any improvement in productivity as a whole. These results do not change a lot when the sector is viewed by disaggregating into 12 industries.
Since the 9th five-year plan, transformation from growth based on intensive usages of inputs to growth based on improvements in efficiency and reforming state-owned enterprises has been emphasized. The results from this study however indicate that productivity improvements have not occurred in Guangxi, suggesting that development of the industrial sector in Guangxi through enhancement of efficiency will not be easy.
