ABSTRACT: In order to
improve the production efficiency of maize in Henan, China, the HP (High-Pass)
filter method is used to obtain the maize trend yield. Secondly, the Malmquist
index method is used to analyze the changes of TFP (Total Factor Productivity)
of maize in 18 cities in Henan Province in the past 11 years. Finally, the
amount of slack in maize input and output is analyzed. The results show that
the research and development level of advanced technology of maize production
in Henan Province has been improved to some extent in recent years; the
advanced technology in various regions has not been fully promoted and
utilized; there is a certain degree of relaxation in the input of various
elements of maize; the resource allocation is unreasonable, and there is a
certain amount of space for saving.
