讨论了复杂大系统，特别是经济系统的智能控制问题，把参与竞争的实体视为模糊可拓经济空间的一个点，把各种限制约束条件视为一个多维界壳，并定义了界壳的约束度。实体在参与竞争时，首先要获取信息，删除噪声，然后寻求界壳与界门，必要时调用可拓力，以达到预定目标。

This paper discussed the intelligence control of the complex large scale systems , especially of the economy system. The entity participated in competition is regarded as a point in the fuzzy extension economy space, and all kinds of restriction conditions as a N-dimensions' jieke. Then the definition of the jieke's restriction degree is given. When the entity participates in competition, it must get the information first, and wipe off the information yawp. In order to find the best jieke and jie-gate, the extension force can be used.
