A Decade Trend of Total Factor Productivity of Key State-Owned Forestry Enterprises in China

Abstract

State-owned forestry enterprises are important elements of the forestry economy in China. The operational efficiency of such enterprises depends on technological progress and other input factors. Total factor productivity (TFP) is an important means to evaluate the efficiency of technical elements. The growth of production efficiency can be classified into efficiency variation and technical variation. The TFP of 135 key state-owned forestry enterprises in the northeast, southwest, and northwest regions of China in 2001-2011 was measured through Malmquist-data envelopment analysis. The technological progress of the state-owned forestry enterprises positively affected TFP variation, but technical efficiency only slightly increased and scale efficiency even negatively affected TFP variation. The average growth rate of TFP in the northwest region is higher than those in the northeast and southwest regions. The Western Development Program of China increasingly contributes to the economic development of western areas. The increasing investment of the government in science and technology accelerates the development of forestry economy in China.

Applying Data Envelopment Analysis and Grey Model for the Productivity Evaluation of Vietnamese Agroforestry Industry

“…For example, Briec et al [14] employed MPI to analyze the productivity growth and technological change of a Portuguese hydroelectric plant in 2001-2008. Yang et al [15] thought forestry enterprises were important elements of the forestry economy in China. The increasing investment of the government in science and technology accelerates the development of the forestry economy in China.…”

“…Referring to the operational characteristics of Vietnamese agroforestry companies and summarizing the DEA literature mentioned in Section 2 [11][12][13][14][15][16]22,23], this research selects total assets, liabilities, and equity as three input factors because they are key financial indicators contributing to the performance of DMUs in the agroforestry industry. On the other hand, net revenue and gross profit are selected as output factors, as they are important indices for measuring the performance of DMUs in the agroforestry industry.…”

“…MPI considers two-period efficiency and technological change in the geometric mean. MPI was defined in Equation (15) and was being used to estimate the change of overall productivity of a pharmaceutical company over time. If MPI > 1 it means overall productivity increases; if MPI = 1 it indicates no change; a MPI < 1, it indicates a decrease of overall productivity:…”

Measuring Eco-Efficiency of State-Owned Forestry Enterprises in Northeast China

“…The output indicators can be divided into desirable and undesirable outputs. According to Yang et al's research [23], desirable outputs include total output and the sale value, both of which can also be accessed from the China Forestry Statistical Yearbook. According to Zheng et al's research [3], undesirable outputs include effluent, exhaust, and solid-waste, all of which can be estimated using data from the China Statistical Yearbook on Environment and the China Forestry Statistical Yearbook.…”

Ethnobotany of Camptotheca Decaisne: New Discoveries of Old Medicinal Uses

“…Application of the leaves as green manure challenges current theory that the Chinese happytree is allelopathic and limits the growth of many crops [15][16][17][18]. According to Yang and Li (1992), in fact, the leaves of the Chinese happytree contain 2.62% N, 0.51% P, 2.56% K in dry weight. Therefore, 500 kg of dry leaves may have the same fertility as 12.75 kg superphosphate, or 65.5 kg ammonium phososphate, or 25.5 kg potassium sulfate [19].…”
