  • 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. They were given a choice between one of two gifts
  • 选择实验中给每个实验对象两种礼物。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
