Off‐Farm Employment and Grain Marketable Surplus in China
研究中国改革时期非农就业对农户粮食商品剩余供给的影响，发现非农收入对粮食商品剩余有显著负向作用，可能导致市场供给减少。
This paper examines the effects of off‐farm employment on grain marketable surplus supply during the reform period in China. A theoretical framework demonstrates that farm households' supply behaviour depends not only on the profitability of farm production but also on alternative off‐farm wage opportunities of household members. An empirical model, which assumes full income maximisation of farm households, simultaneously evaluates the effects of on‐farm and off‐farm income on their grain supply behaviour. Particular attention is paid to the effect of off‐farm income through a comparison of conditional and unconditional grain marketable surplus supply elasticities. Results show that off‐farm income had a strong negative effect on grain marketable surplus from farm households following liberalisation of factor markets in China and that this could lead to a loss of marketable surplus supply.
