And it was followed by a choice experiment
之后還有一個選擇實驗
This was a choice experiment with price and taste randomization
實驗中價格和味道進行了隨機
We're then able to achieve statistical identification through
這讓我們之后能通過統計得出結論
having both price and breed, breed being tastes randomized in this slight randomized characteristics which are in red
這里價格和品種進行隨機，種類也就是味道隨機的內容用紅色顯示
And this choice experiment involved giving people a choice actually to the survey
選擇實驗中給每個實驗對象兩種禮物
They were given a choice between one of two gifts
二選一
And this gifts was two different discount vouchers that they could use to buy chicken
禮物是兩種不同購雞折扣券
with the vendors that were in the project that was working with
到我們的合作商販能得到對應折扣
So the first choice, we call option one that was always a random discount for safe crossbred chicken
第一個選項是安全雜交雞的隨機折扣
By safe, I mean the chicken that was produced the project that I talked about
安全，我指的是按照之前流程生產的雞
And option two was always a random discount for regular crossbred or local chicken
而選項二則是隨機折扣外加普通雜交雞或土雞隨機選擇
This was just the normal chicken that was sold on the market that didn't have anything to distinguish of
也就是市場上無法辨別是否安全的普通雞
So it's an example of how I did randomization
這就是進行隨機的例子
First of all, I can randomize the value of the discounts
我可以隨機化折扣值
And I could also randomize the value of discounts and the breed of option two
也可以像選項二，隨機化折扣，同時隨機化品種
So as my results, I found a willingness to pay for safety labeling is about 10 to 15% of current market prices which is quite significant
結果發現，人們愿意為安全標簽支付的錢，約占當前市場價格的10-15%，非常顯著
However, the willingness to pay for local breeds or for taste is actually higher than the willingness to pay for safety labeling
而人們對土雞或味道的意愿比對安全標簽的意愿更高
So taste and safety are both very important characteristics
味道和安全都是重要特征
