Abstract:China's eastern area is at middle and later stage of industrialization during which the relation between ur ban and rural areas,industry and agriculture appears maladjusted The main problems are shrinkage in agricultural somparative earning and lack of driving force of agricultural development.Based on calculating agricultural labor productivity in east China from 1996 to 2005,this paper analyzes contributing degree of motive forces of agriculture develop in ten provinces and cities of east China applying GCA (Grey correlative analysis).The results show that there is no absolute correspondence between the level of industrialization and agricultural labor productivity in Chi,na's cotstern area.There is no synchronous development between industry and agricultural labor productivity in some areas.Fertilizer and agricultural machinery input had high contributing degree for ten years; however,contributing degree in land and irrigation work input was low.Non-materialization inputs became the leading role in most provinc,es and cities' increase of agricultural labor productivity.Modern agricultural development need non-materializationinputs as primary motive.force,at the same time,direct material input and facility input as guaranteed function.Forsome reasons,agricultural development is characterized by "more direct material input,less facility input" in east China now.Optimal driving force model of future agricultural development in east China is that non-materializatior inputs are dominant that perfected facilitv input are guarantee,and that certain substance inputs are necessary.
