Abstract
This project aims to use education on technology and market information as a treatment in a randomized controlled trial (RCT) in Hebei Province of China, covering approximately 1500 farm households. The goal is to investigate how technology and market information affect the adoption of HEWIT, and to examine the impacts of these advanced agricultural irrigation technologies on agricultural performance, including operational decisions and farm outputs.

Experimental Design

Experimental Design
There are two focused HEWITs, including Mobile Sprinkler Irrigation and Reel Irrigation Machine. Technology information and market information on them will be our information treatments.

Randomization Method
randomization done in office by a computer
Randomization Unit
Group level randomization for some treatment, and individual randomization for some treatments.
The RCT will be nested in a large-scale field household survey conducted in Hebei Province in China, designed to evaluate the policy impact of Chinese government’s police intervention for groundwater overexploitation control.
Two types of surveys will be conducted. The first type is “regular farm household survey”, which will be done at villages. 944 households in 148 villages will be surveyed. The second type is “professional farm survey”, which aims to interview the farmer with farm size larger than 50 mu. Around 500 professional large farmers will be surveyed. Randomization will be done in both of the surveys.
Village level randomization for “regular farm household survey”, and individual randomization for “professional farm survey”.
Was the treatment clustered?
Yes
