    研究表明，我國目標出口退稅機制需要從五個方面進行構建：即增值稅制度改革、退稅率設置、退稅管理辦法統一、退稅財政分擔優化和退稅管理的強化，最終方可達到總體退稅成本最低和退稅收益的最大化。更具體地說，一是改革現行增值稅制度，將我國增值稅制度由生產型逐步轉為消費型，並強化征稅管理，為退稅機制的優化奠定基礎；二是在綜合考慮國內國際實際情況的前提條件下，選擇適宜我國的「中性與非中性」相結合的退稅率，並建立一套具有相對穩定性和適時靈活性的彈性退稅率機制；三是伴隨著外貿體制改革的進一步深化和退稅管理能力的逐步提高，將現行兩種出口退稅管理辦法逐步過渡到以「免、抵、退」為主的單一管理辦法；四是改革現行增值稅共享辦法，建立「先退稅后共享」的新型退稅負擔機制；五是建立一套針對出口企業和稅務機關的激勵約束機制，有效強化出口退稅的管理。

But, pso convergence ' s speed become slow in latter iterative phase, and pso is easy to fall into local optimization. at present, some scholars improve base pso mostly using 3 methods : disperse algorithm, increase convergence speed, enhance particle ' kinds. in the paper, i put forward 2 methods aiming at local best resutl but not whole best result. i modify base pso using the last method. some scholars put forward times initializations, so i select best result after circulating some times to be a parameter of formula. first, put particle into some small region, and ensure every region having one paticle at least. second, every region ' s particle has probability transfer other regions. although increase running time, enhance particle ' kinds, decrese the probability of convergence far from whole best result. nerms ( network educational resource management system ) is one of the research projects in the science and technology development planning of jilin province. the aim of nerms is to organize and manage various twelve kinds of network educational resources effectively so that people can share and gain them easily and efficiently, so as to quicken the development of network education

    但粒子群演算法仍存在如下不足:首先在多峰的情況下，粒子群有可能錯過全局最優解，遠離最優解的空間，最終得到局部最優解;其次在演算法收斂的情況下，由於所有的粒子都向最優解的方向群游，所有的粒子趨向同一，失去了粒子間解的多樣性，使得後期的收斂速度明顯變慢，同時演算法收斂到一定精度時，演算法無法繼續優化，本文對原始粒子群演算法提出了二點改進方案: 1 .演算法迭代到一定代數后，把此時找到的全局最優解當作速度更新公式的另一參數（本文稱之為階段最優解）再進行迭代; 2 .每次迭代過程中除最優解以外的每個粒子都有一定概率「變異」到一個步長以外的區域，其中「變異」的粒子在每一維上都隨機生成一個步長。
