【文章內(nèi)容簡(jiǎn)介】 neously, researches on watersaving technology adoption in China by the academic circles are quite limited. The scarce documents available, which study the watersaving technology adoption, are mainly cases study and qualitative analysis, lacking in quantitative analvsis. Therefore, this paper employs data from ten provinces in China to carry out a quantitative analysis of the status quo of agricultural watersaving technology adoption and its determinants. What on earth is the current adoption extent of watersaving technology in China? Which factors may have remarkable effect on its adoption? What roles do shortage of water resources and governmental policy play? Specifically speaking, this paper has two purposes: firstly to describe the changing tendency of watersaving technology adoption and secondly to identify the determinants affecting this adoption This paper is anized as follows: introduction data sources, types, status quo and changing tendency of watersaving technology adoption。 descriptive analysis on watersaving technology adoption。 econometric analysis and results。 conclusion and policy implications. 2. Data, types, status quo and changing tendency of watersaving technology adoption The watersaving technology defined by us refers to perceptible watersaving irrigation technology at field level. Likewise, the definition of water use efficiency also means crop yield per unit water input measured at field level, for watersaving technology adoption is found not watersaving in some conditions when the water use amount is measured in the overall irrigation system or on the drainage area scale. This is because the watersaving nature of each technology is not only determined by technological characteristics but also by factors like hydrological system and economic adjustment of output . 2. l Data source Data employed in this paper derives from field investigation of three projects done by the Center for Chinese Agricultural Policy (CCAP) The first project was investigation on China39。s water right system and management panel data. This investigation is divided into two phases: during the first phase, investigation was done in Henan, Hebei and Ningxia in 2021 and the investigation period was respectively 1990, 1995 and 2021。 during the second phase, followup investigation was performed in Henan and Hebei in September, 2021. To add data to2021, another followup investigation was pleted in Ningxia in August, 2021. The investigation of this project randomly sampled 77 villages based on the scarcity degree of water resources. The second project was investigation on water resources of Northern China in December, 2021. 6 provinces were investigated, including Henan, Hebei, Shannxi, Shanxi, Inner Mongolia, and Liaoning. The invested periods were 1995 and 2021 make the research more representative, we adopted the way of randomly stratified sampling to select sample villages in Northern China. Firstly, we selected counties in each sample province and then divided them into 4 categories in accordance with their irrigation area, namely sever water shortage, partial water shortage, normal and absolute water shortage (mountain areas and deserts). We randomly sampled 2 townships in each county and 4 villages in each county. The second investigation collected 401 sample villages. The third project was investigation on waterconsuming consortiums of 3 provinces in July, 2021, including Gansu, Hubei and Hunan. We adopted the randomly stratified sampling based on scarcity degree of water resources in 1995 and 2021 respectively. Altogether 60 sample villages were selected. Investigation of the first and second projects collected 478 sample villages and investigation of the third obtained 60 sample villages. Therefore, there are a total of 538 samples from the three investigations. As samples of the final investigation are data of 2021, we deal with all data of 2021 in accordance with those of 2021 in consideration of consistency. Types of adopted watersaving technologies Based on investigation of 538 villages in 10 provinces, we have found that there are various types of watersaving technologies in the rural area. To facilitate analysis, we categorize them into three types in accordance with capital needed, separability and time of adoption. The first type is traditional watersaving technologies including border irrigation, furrow irrigation and land leveling. We categorize these technologies into the same type as they were adopted rather early and some were adopted in 1980s prior to agricultural reform as most village leaders reflected. Besides, these technologies have relatively low fixed cost and are separable for each household to operate independently. The second type is householdbased watersaving technologies which include ground pipes (film plastic pipe or water bags), plastic film cover, leaving stubble to avoid plough (wheat straw covering), intermittent irrigation and antidrought breeds. Normally this type of technologies can be adopted by a single household (rather than village mittees or farmer household group). In addition, they have relatively low fixed cost but high separability. In parison with traditional technologies, these types of technologies were adopted later. The third type is munitybased watersaving technologies which include underground pipes, sprinkler irrigation, drip irrigation and antiseepage channel. These types of technologies are usually adopted by the munity or farmer group instead of individual farmer household as they demand equipment with relatively high fixed cost and require cooperation of the collective or the majority of farmer households. Compared with the previous two types, these technologies were not adopted by farmers until recent years. Status quo and
