consumer demand is the original stimulate pulling economic growth. Consumption, in the process of economy growth, plays an important role, and its main functions is embodied in the following aspects: From the demand of economy, consumption has direct and indirect to boost world economic growth;from supply, consumer can create human resources necessary for production development, so as to create social productive forces;From the structure, the change of consumption structure is the basic reasons of industrial structure change, which can guide constantly upgrading of industrial structure and promote economic growth. In this paper, we, at first, put forward the background and significance of the research on town residents’ consumption structure in Jiangxi Province. Second, we briefly introduced the basic principle of extended linear expenditure system model (ELES) what would be used in this paper. Then, we, according as the data of consumption structure in recent years, used ELES to made an empirical analysis. Finally, we made a summary.

The proposed algorithm relies on a group of new formulas for calculating tangent slope so as to address angle feature of edge curves of image. It can utilize tangent angle features to estimate automatically and fully the rotation parameters of geometric transform and enable rough matching of images with huge rotation difference. After angle compensation, it can search for matching point sets by correlation criterion, then calculate parameters of affine transform, enable higher-precision emendation of rotation and transferring. Finally, it fulfills precise matching for images with relax-tense iteration method. Compared with the registration approach based on wavelet direction-angle features, the matching algorithm with tangent feature of image edge is more robust and realizes precise registration of various images. Furthermore, it is also helpful in graphics matching.
