Competition or Combination Between Grain and Cotton?Study on Utilization Efficiency and Economic Benefits of Grain and Cotton Cultivated Land in Modern North China
Taking Cotton cultivation industry as the starting point,this paper collated historical infor-mation such as Buck survey,Chen Hansheng survey and Manchurian Railway Rural survey.And it was found that the promotion of American cotton had changed cultivation structure to a certain extent in modern North China.There was a phenomenon of"land competition"between grain and cotton.Meanwhile,the cul-tivation pattern tended to be"grain and cotton combination".Using three indexes of land use intensity,land productivity and land profit rate,this paper analyzed the land economic efficiency of each crop,and then ex-plained the influence of cotton cultivation industry on the land resources utilization of peasants in North Chi-na.It was found that the land use intensity,land productivity and land profit rate of cotton cultivation were higher than that of grain.Compared with other grain,Cotton cultivation could promote peasants to make full use of family labor,improve land use intensity,and increase land productivity and land profit rate.From the perspectives of technical threshold,downstream industry and natural environment,it could explain the rea-son that peasants still choose to plant food crops under the drive of interests.
