This paper analyzes the current development of industry clusters of the industrial parks in Jiangxi. It is found that most of the industrial parks are in the stage of agglomeration, others are in the transitional phase from agglomeration to cluster and the remaining, namely about the one-third industrial parks, are still in the concentrated phase. There is a large gap between the development of the industrial parks in Jiangxi and the requirements of industry clusters, which is embodied in the fact that the industrial structures converge, the growth of industrial chain is incomplete and the supporting system of production is imperfect. Finally, the countermeasures are proposed from the perspective of the government to promote the development of industry clusters of the industrial parks in Jiangxi. These countermeasures mainly are to make the industrial orientation clear, to plan a good industrial layout, to develop the industrial parks based on the mechanism of industriy clusters, to actively explore appropriate development models, to strengthen the construction of industrial supporting system and to create an innovation environment for industry clusters in the industrial parks.
