Optimization of Industrial Structure in Henan Province—Based on the "12 th FYP" Energy-Saving Goals *

It is an urgent problem that how to make the industrial structure adjustment beneficial to the achi- evement of the energy-saving goals. According to "the 12 th Five Years" economic development and industry planning in Henan province, bottom-up sector decomposition method was firstly used to predict energy con- sumption and energy intensity of various sectors and the added value and energy consumption of industry could be got under planning scenarios before the industrial structure optimization. Then the constraint condi- tions were chosen to build dynamic gray linear programming model for the optimization of industrial struc- ture. Finally, LMDI method was used to decompose energy consumption to verify whether it was more con- ducive to energy conservation by model optimized. The result showed that industrial structure optimized could ensure a reasonable economic growth and a completion of energy efficiency goals. From the perspective of decomposition results of energy consumption, the industrial structure after a grey linear programming model optimized showed a more obvious suppression on energy and it was more conducive for energy conservation.
