Comparative and empirical analysis about input-output on suburban and rural areas

Based on the comparative analysis between suburban and rural vegetables in 2011-2012, the input-output relationship of suburban vegetable from 1998 to 2012 was analyzed using cointegration test, impulse response function and variance decomposition. The comparative analysis showed that: suburban vegetable input-output efficiency was in decline, rural vegetable input-output efficiency was rised; The empirical analysis shows that: vegetable planting labor costs and material costs existed long-term stable relationship with vegetable yields, but the vegetable yield itself had a certain lag effect, the second was material cost, the last was labor cost. So establish and improve the safeguard mechanism, enhance the quality and innovation ability , increase the technical inputs are important measures to improve the relations between input and output of suburban vegetable.
