Modelling Analysis of Forestry Input-Output Elasticity in China

Based on an extended economic model and space econometrics, this essay analyzed the spatial distributions and interdependent relationships of the production of forestry in China; also the input-output elasticity of forestry production were calculated. Results figure out there exists significant spatial correlation in forestry production in China. Spatial distribution is mainly manifested as spatial agglomeration. The output elasticity of labor force is equal to 0.6649, and that of capital is equal to 0.8412. The contribution of land is significantly negative. Labor and capital are the main determinants for the province-level forestry production in China. Thus, research on the province-level forestry production should not ignore the spatial effect. The policy-making process should take into consideration the effects between provinces on the production of forestry. This study provides some scientific technical support for forestry production.

Exchange Rate and Purchasing Power Parity in China Soybean Trading to USA, Argentina, and Brazil, 1999-2010

This article researches fluctuation of exchange rate has impacts on China import unit price of soybeans trading to USA, Argentina, and Brazil. Based on yearly and monthly bilateral soybeans trade data from 1999 to 2010, empirical results show that exchange rate is statistically significant to China import soybeans unit price changes in either a long run or a short run. Although dollar value of USA currency depreciation has negative impact on the exporting amount of USA soybeans, the pattern of trade in dollar values did not shift from 1999 to 2010 no matter how international trade organizations influence on trading coordination. Empirical analysis based on monthly USA-China bilateral soybeans trade data from 1999 to 2010 indicates that the volatility of the exchange rate faces a declining trend that may trigger threshold effect on China import unit price changes. Thus, trading large amount of heavy goods to China in a short period can consolidate purchasing power parity of dollar value of USA currency and affect Argentina and Brazil exporting unit price and world price changes even if it faces to a declining trend.
