區(qū)域經(jīng)濟單位GDP能耗的解析研究
[Abstract]:Energy is an important strategic material. The scarcity and non-renewable of energy make it the most important material related to people's livelihood and social and economic development. The energy efficiency of regional economy has become a hot issue in recent years. This paper takes Liaoning Province as an example to analyze the energy consumption of regional economy unit GDP. In this paper, the relationship between economic growth and energy consumption is studied, in order to grasp the change law of energy consumption per unit GDP of regional economy, to construct reasonable and effective prediction, early warning method and system of unit GDP energy consumption, in order to change the mode of development. Promote regional economic and scientific development, build a resource-saving, environmental-friendly society to provide adequate protection. This paper mainly studies the influencing factors of unit GDP energy consumption. Based on the analysis and statistics of a large number of relevant data, the prediction and early warning model of unit GDP energy consumption in regional economy is established. The contents of the work are divided into the following five aspects: 1) according to the actual situation, the relevant data published and recorded by the Bureau of Statistics are analyzed, and the electricity consumption and production value closely related to the energy consumption per GDP are mainly studied. Based on the data of industrial structure and energy consumption structure, the correlation of data is analyzed, and the statistical value of electricity consumption, historical energy consumption and historical GDP are used as the basis of the prediction and early warning model. On this basis, the data is preprocessed to lay a data foundation for the construction of unit GDP energy consumption prediction model. (2) aiming at the problem of less data in the research, the support vector machine (SVM) algorithm is used to build the model. In order to further improve the accuracy of the established model, the particle swarm optimization algorithm (PSO) is used to optimize the parameters of the SVM algorithm. The experimental results show that the proposed algorithm can better follow the change of the actual situation, the prediction error is low, and it can meet the actual demand of 3. 3) the prediction results of unit GDP energy consumption can be analyzed. According to the given unit GDP energy consumption warning range, the unit GDP energy consumption warning is realized. The early warning of unit GDP energy consumption is another form of prediction results, which can more intuitively represent the predicted results and provide data support for decision makers.) the relevant factors that may affect the unit GDP energy consumption are studied. The relationship between industrial structure, energy consumption structure and energy consumption per unit of regional economy is analyzed qualitatively and quantitatively. The possible factors and ways of influencing energy consumption per unit GDP are analyzed, and the efficiency of energy utilization is improved. The theoretical direction of reducing the unit GDP energy consumption and providing operational direction 5) combined with the prediction and early warning algorithm proposed in this paper, a regional economic unit GDP energy consumption prediction system and its early warning subsystem are constructed. On the basis of realizing data management and other basic functions, the system has better prediction ability of unit GDP energy consumption, and the relative error between predicted value and actual value is small, which meets the management requirements of unit GDP energy consumption. At the same time, based on the prediction and analysis results, the system constructs a unit GDP energy consumption warning subsystem, and provides a variety of results display methods to achieve good human-computer interaction.
