Study On The Scale Compensation Of Forestry Investment In Heilongjiang Reclamation Area

The Central Committee of the Communist Party of China, Heilongjiang province and Heilongjiang Reclamation Area have attached great importance to the development of ecological forestry, protecting forest resources and accelerating the construction of forestry economy. Under the background, the output elasticity value and the returns to scale value of three types of input factors(forestry area, fixed investment, forestry practitioners) are calculated in Heilongjiang Reclamation Area,which could make clear the sensitivity degree of the total output of forestry to the change of input factors and the influences of increasing or decreasing output, and the rationality of factor input is analyzed. Reference suggestions are provided from the aspects of adjusting the inputs of production factors for the forestry economic growth in Heilongjiang Reclamation Area.Based on the existing researches, using the C—D production function, according to the Heilongjiang reclamation area statistical yearbook(1993-2015) data(1993-2015), with the total output value of forestry as dependent variable, forestry land area, the forestry fixed assets investment and forestry professionals as the independent variable data, the elastic values(7.85607 p=0.00020; 0.40394 p=0.00152;1.43197 p=0.01519)of the three input factors are calculated respectively. The output elasticity of forest land area is the largest and the scale return value of three input factors of the total output is 9.69198 in the study period.The results of the study show that during the study period, the returns to scale of forestry input elements is increasing; three input factors(lagging of the forestry land area or current forestry area, lag a fixed assets of forestry investment and current forestry practitioners number) can increase the forestry output value. Among them,the forest land area is the largest contribution to the total output value of forestry.,followed by forestry practitioners and finally the forestry investment in fixed assets.
