Abstract: The environment deterioration has become a focus of concern with developing of the socio-economic. In this paper, taking Shandong Province as an example, the authors analyze the relationships between the economic growth and agricultural non-point source pollution mainly from the quantitative aspects. The density of agricultural inputs, the density of pollutants in livestock and poultry are selected as a measure of pollutant discharge agricultural non-point source pollution emissions target. The per GDP are selected as an indicator of economic growth. The result shows that the density of inputs is a unilateral Granger cause of economic growth. However, there is no obvious Granger causality between the density of pollutants in livestock and poultry and economic growth. With the development of the economy, we must pay attention to controlling the amount of chemical fertilizer, understanding the input of pesticides the contribution to economic growth.

Abstract: This paper analyzes the energy consumption of Shandong Province by the use of Complete Decomposition Model. We decompose three key factors: economic growth, structure and energy intensity, and study the impact on energy consumption results brought by changes in these variables. The corresponding effect coefficients is compared with national average level to identify the characteristics of energy consumption changes in Shandong and specific effect s of every stage of each factor, providing a scientific basis for the development of energy policy making.

Abstract: The relationship between energy consumption and economic growth has long been the focus at home and abroad. The general view is: energy consumption promotes economic growth; economic growth affects energy consumption on the other hand. In sight of the original theory, this paper adopts the statistical data of Shandong Province from 1980 to 2008, which include Gross Domestic Products (GDP), energy consumption, fixed asset investment and employees. Using unit root, co-integration and Granger causality test, we examined the relationship between energy consumption and economic growth in Shandong Province. The results show that energy consumption and economic growth have long-term trend relation, and there is two-way causality between them. The econometric model is estimated using Generalized Least Square (GLS) method. The conclusions are as follows: energy consumption and economic growth is positively correlated in Shandong province, and economic growth has highly depended on energy consumption.
