Based on the geographic information system (GIS) technology, this paper tries to measure and analyze the changing trend of regional development equilibrium of Jiangsu Province since 1990. Firstly, we use the regional barycenter model, take a visible measurement on the temporal-spatial distribution and movement tendency of geometric centroid, population centroid, GDP centroid, foreign capital(FDI) centroid, and then combine them with related statistics indexes under the different dimensions to analyze the temporal-spatial characteristic of economic equilibrium in Jiangsu. The conclusions are drawn as follows: (1) Compared to the population centroid, Jiangsu's GDP centroid and the FDI centroid show a marked deviation. The population centroid moves from southeast to northwest, to southwest, and again back to northwest, showing a converse "U" moving trend. The GDP centroid shifts toward southeast. But the FDI centroid takes 2003 as an inflection point, moving towards the south before that and toward the northeast after that gradually. (2) The economic disequilibrium is mostly turning worse in Jiangsu. The relative development rates present south-north unbalance and county downtown unbalance. And the internal unbalance of the south, middle, north of Jiangsu also have their own characteristics. (3)The counties, which have an accelerating relative development rate in this century is mainly located in the four corners of the southern and middle of Jiangsu, showing a "口" shaped pattern, while those with a descending relative development rate mainly in the northern of Jiangsu. and (4) The convergence among the three spatial regions of Jiangsu and within every spatial unit is increasingly stregthened. Southeast Region of Jiangsu demonstrated a highly developed convergence zone at the core of Suzhou Wuxi, while Northern Regions of Jiangsu shows a rapidly developing convergence zone, which is represented by Yancheng municipality, and a slowly developing convergence zone, which is represented by Lianyungang municipality.
