The surviveand development of CA law system can not leave the certain material life condition andcertain production pattern, so, different CA ecology reflects different economy foundation: Traditional accusatorial action based on the ethics order is co-related with the originaleconomy ecology; Traditional inquisitorial action based on the administrative order isco-related with developed cultural economy ecology. The difference of western economyecology and eastern economy ecology leads to the different genes though them faced thesame traditional inquisitorial action. The modern CA based on the law order lies on thedeveloped commercial economy, the mature market economy and modern citizen societybring about the modern CA ecology whose task is resolve the action contradiction withration.

刑事诉讼法律制度的生存和发展同样不能离开特定社会的物质生活条件,生产力水平与生产方式等条件,因此,不同的刑事诉讼生态反映的是完全不同的经济基础:以伦理秩序为特征的弹劾式诉讼与原始经济生态密不可分;而以行政秩序为特征的纠问式诉讼与较为发达的农业经济生态互为依存,当然也正是由于西方封建经济生态与东方社会封建经济生态的巨大差异导致同样的纠问式诉讼孕育着不同的系统突变基因;以法律秩序为特征的现代刑事诉讼则立基于高度发达的商品经济生态基础之上,比较成熟的市场经济环境和现代市民社会的形成不断地催生着以理性解决严重刑事冲突的现代刑事诉讼生态。
