Abstract
The aim of this paper is to evaluate the total factor productivity (TFP) growth of national parks in China. The method of Malmquist Productivity Index based on data enveloped analysis is used. The result shows that 58.33% of national parks in China improved their TFP, and their mean score reached 3.42 in 2001–2005. When the decompositions are considered, 90.28% of them decreased their efficiency and 98.59% of them increased their technology. Correlation analysis indicates that these national parks' TFP is more constrained by their efficiency change than technology change. The correlation coefficients of them with Malmquist Productivity Index (MPI) reach to 0.7834 and 0.9367, respectively. Overall, the authors hold the opinion that most national parks in China increased their TFP during this period, but hindered by their inputs scale for preservation function, the efficiency of them deteriorated but the technology increased, further influencing the TFP. Finally, some methods to improve the performance of national parks for the governments and managers are discussed.
