Metrics analysis of substitution elasticity of wheat seed input

In recent years, with deepening of supply side structural reform, wheat demand has shifted from quantity based to quality based．Improvement of wheat seeds can significantly enhance production quality．Using seeds as a starting point, based on panel data of various indicators from 14 major wheat producing areas from 2005 to 2020, a transcendental logarithmic cost function model was adopted to calculate demand price elasticity and substitution elasticity of wheat seed factors, and analyze differences among major wheat producing areas．
