And it was followed by a choice experiment
之后还有一个选择实验
This was a choice experiment with price and taste randomization
实验中价格和味道进行了随机
We're then able to achieve statistical identification through
这让我们之后能通过统计得出结论
having both price and breed, breed being tastes randomized in this slight randomized characteristics which are in red
这里价格和品种进行随机，种类也就是味道随机的内容用红色显示
And this choice experiment involved giving people a choice actually to the survey
选择实验中给每个实验对象两种礼物
They were given a choice between one of two gifts
二选一
And this gifts was two different discount vouchers that they could use to buy chicken
礼物是两种不同购鸡折扣券
with the vendors that were in the project that was working with
到我们的合作商贩能得到对应折扣
So the first choice, we call option one that was always a random discount for safe crossbred chicken
第一个选项是安全杂交鸡的随机折扣
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产的鸡
And option two was always a random discount for regular crossbred or local chicken
而选项二则是随机折扣外加普通杂交鸡或土鸡随机选择
This was just the normal chicken that was sold on the market that didn't have anything to distinguish of
也就是市场上无法辨别是否安全的普通鸡
So it's an example of how I did randomization
这就是进行随机的例子
First of all, I can randomize the value of the discounts
我可以随机化折扣值
And I could also randomize the value of discounts and the breed of option two
也可以像选项二，随机化折扣，同时随机化品种
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
结果发现，人们愿意为安全标签支付的钱，约占当前市场价格的10-15%，非常显着
However, the willingness to pay for local breeds or for taste is actually higher than the willingness to pay for safety labeling
而人们对土鸡或味道的意愿比对安全标签的意愿更高
So taste and safety are both very important characteristics
味道和安全都是重要特征
