Grain Consumption and Its Influence of Agricultural Transfer Labors in China: An Investigation on Migrant Workers

There is no statistical monitoring on the grain consumption of agricultural labors' transference in China's statistical system. Using data of migrant workers' grain consumption survey of China, this paper identifies the grain demand and its structure of migrant workers. Moreover, this paper employs a hybrid growth model of "power exponent + exponent", combining with Least Absolute Deviation, to estimate the number of migrant workers in China. And to quantify the impacts on grain consumption of agricultural labors' transference:the climbing grain demand from the perspectives of the pull effect caused by rapid increase of rural migrants and the possible underestimated grain consumption by them. This paper aims to provide comprehensive policy implications of rural-urban migration on grain consumption in China, firstly to ensure gain safety, secondly to stabilize rations product and expand the feed, then to guide gain consumption, and to strengthen monitoring of their gain consumption.
