问题如下：

Which of the following is most likely classified as secondary ESG data?

选项：

A.Surveys

B.News articles

C.ESG scores by rating agencies

解释：

C is correct because "many ESG databases provide secondary ESG data or ratings. These are assessments transformed by a process of scoring or a formula from a primary data source … Secondary data sources typically involve transforming the primary ESG data in some way and creating new scores, assessments or ratings based on these transformations. These are available from commercial organizations, both financial and non-financial, as well as regulators, NGOs and other non-profit or charitable bodies."

A is incorrect because "primary data can be sourced from companies directly: surveys … Indirect assessment can be via a third-party source (such as Glassdoor for employee satisfaction data and scores, which are directly sourced from employee surveys)."

B is incorrect because "primary data can be sourced from companies directly … Alternatively, the source may be indirect, via: news articles."

是不是可以理解为一手数据、二手(加工过）数据？

嗨，努力学习的PZer你好：


是的~同学的理解是正确的。

  • Primary Data: 这是直接从源头收集的数据，特别是为了特定的研究目的或项目而设计和收集的。例如，通过调查、实验或观察直接得到的数据。这类数据最大的优点是精确对应研究需求，但收集过程可能耗时且成本较高。
  • Secondary Data: 次级数据是指已经存在的数据，这些数据原本是为了其他目的收集的，但可以被用于新的研究。例如，政府统计数据、历史记录、以前的研究报告等。这类数据容易获取且成本较低，但可能不完全符合新研究的具体需求。
