rate of net output

In view of input-output method being generally acknowledged riper in the world, when we evaluate mulberry field with input-output method income price of mulberry field is mainly determined by silkworm net income and capitalization rate for the land.

鉴于投入产出法是国际上公认的比较成熟的土地估价方法之一，利用投入产出法对桑园估价，桑园收益价格主要由桑蚕净收益及土地还原利率决定。

Using the Back-Propagation ( BP) of Artificial Neural Net ( ANN), putting in the main effect-factors of capitalization rate, and then the BP net will train thousands of times till the result go steady, that is the output of the net, capitalization rate.

将人工神经网络用于确定资本化率，输入影响资本化率的主要因素，利用BP网络的自适应学习的特点进行反复训练和自我学习，可得出趋于稳定的输出，即资本化率。
