Conditional information entropy was used to compute relevance of attributes and it was used in fitness function to assure reduction has fewer attributes and relevance of attributes.

利用条件墒计算属性问的相关性，并将其引入到适值函数中，可以保证所求约简含有较少的属性而且属性间的相关性较小。

At first, analyze the farmer's desire for the pension by Rough Set theory, construct the attribute reduction algorithm based on the conditional entropy for the computation and analysis of 8,410 questionnaire surveys data to make use of the advantage of rough set to deal with indefinite and incomplete data.

首先利用粗糙集理论理不确定和不完整数据的优势，基于改进的基于条件熵的属性约简理论对8410份问卷调查数据进行计算与分析，得出与农民参保意愿密切相关的几个因素，如年龄、性别、收入、行业等。

Using conditional entropy as the heuristic information, it does not compute the core attribute, attribute reduction starts from the condition attributes directly.

该算法利用条件熵度量属性的重要性，不计算条件属性的核，直接在条件属性的基础上约简。

The current real estate\'s industry tax policy\'s characteristic is, in the real estate sale, the hiring, in the transfer circuit levies the categories of taxes to be excessively many, the tax burden to be overweight, holds stage the tax burden to be relatively quite low, has provided the opportunity congenially for the real estate, under the appropriate external environment, easy to initiate the entire profession the congenial behavior.

合理的房地产税收政策应该具有前瞻性和导向性，我们通过立法改变地方政府对房地产企业乱收费的现状，通过在中央政府和地方政府之间重新分配税收收入，减少地方财政收入对房地产企业的依赖，通过简并税种适当降低房地产开发阶段的税负水平，通过实行差别税率来减少房地产投机行为，通过完善保有阶段的税(来源：ABC0e论文网www.abclunwen.com)种设置和房地产评估机制，使闲置不用的房产都能流入市场，解决供求矛盾问题，通过充实房地产业的税收优惠政策来体现我国政府对房地产行业发展的导向作用。
