Abstract:

[Objective] In order to provide evidences for judging the economic development pattern of forestry in China, China's forestry total factor productivity (FTFP) and its components under multiple targets of maximizing economic, ecological and social benefits are measured and analyzed. [Method] With input variables including forest area, year-end forestry employees of forestry and investment in fixed assets of forestry, and with output variables including primary-industry product of forestry, stock volume of forest and timber production,based on the panel data from provinces over the period from 2004 to 2012, FTFPs(Malmquist productivity indexes)and their components in China and in China's four main regions are measured and analyzed using the DEA-Malmquist index methods described in Färe et al.(1992; 1994), and calculated by the software DEAP Version 2.1. The components include technical progress change index, and technical efficiency change index (consisting of pure technical efficiency change index and scale efficiency change index). Every index minus 1 is its growth rate, and the sample averages are all geometric means. [Result] China's FTFP, technical progress, technical efficiency, pure technical efficiency and scale efficiency respectively exhibit average annual growth rates of 15.6%, 14.1%, 1.3%, 1.6% and -0.2% over the period from 2004 to 2012. China's four main regions are in descending order of average annual growth rate (AAGR) of FTFP: eastern region (at an AAGR of 21.8%), central region (18.4%), western region (10.7%) and northeastern region (10.1%). In descending order of AAGR of technical progress, they are eastern region (21.2%), central region (17.8%), northeastern region (9.0%) and western region (7.9%). In descending order of AAGR of technical efficiency, they are western region (2.5%), northeastern region (0.9%), central region (0.6%) and eastern region (0.4%). In descending order of AAGR of pure technical efficiency, they are western region (2.7%), central region (1.3%), northeastern region (1.2%) and eastern region (0.5%). In descending order of AAGR of scale efficiency, they are eastern region (0%), western region (-0.2%), northeastern region (-0.2%) and central region(-0.7%).[Conclusion] Based on the changes of all indexes during the period from 2004 to 2012, China's FTFP shows a growing trend, and technical progress is the primary momentum of FTFP growth. However, technical efficiency has a poor effect on the promotion of China's FTFP, for the growth of technical efficiency is restricted due to the non-synchronous growth of scale efficiency.The FTFPs in China's four main regions all have grown, but there are significantly regional variations in growth rate and there are also regional differences in growth momentum. Therefore, in order to promote FTFP and accelerate changing the economic development pattern of forestry, we should make forestry technical progress, improve forestry technical efficiency, and adopt the corresponding forestry development policies according to the regional features as well.
