Forecasting Natural Gas Demand in China : Logistic Modelling Analysis

Natural gas has increasingly appeared as an important policy choice for China's government to modify high carbon energy consumption structure and deal with environmental problems. This study is aimed to develop the logistic and logistic-population model based approach to forecast the medium- (2020) to long- (2035) term natural gas demand in China. The adopted modelling approach is relatively simple, compared with other forecasting approaches. In order to further improve the forecasting precision, the Levenberg–Marquardt Algorithm (LMA) has been implemented to estimate the parameters of the logistic model. The forecasting results show that China's natural gas demand will reach 330–370 billion m3 in the medium-term and 500–590 billion m3 in the long-term. Moreover, the forecasting results of this study were found close in studies conducted by the national and international institutions and scholars. The growing natural gas demand will cause significant increase in import requirements and will increase China's natural gas import dependency. The outcomes of this study are expected to assist the energy planners and policy makers to chalk out relevant natural gas supply and demand side management policies
