Land rental market, off-farm employment and agricultural production in Southeast China: A plot-level case study

This paper performs a plot-level analysis of the impact of land rental market participation and off-farm employment on land investment, input use, and rice yields for 215 plots cultivated by 52 households in three villages in Northeast Jiangxi Province. Our findings show that households that rent extra land are relatively more productive, but contradict results of earlier studies which found that tenure status of plots affects the level of land investments. We further find that off-farm employment does not significantly affect rice yields. This result contradicts those of earlier studies which found that the negative lost-labor effect of off-farm employment dominates the positive income effect. Another novel finding is that people working locally off-farm tend to switch from green manure planting towards the use of organic manure on their rice plots. We conclude that policies that will further stimulate the development of land rental markets, which is still in its infancy, can contribute significantly to higher rice production in Southeast China. Another implication of our results is that worries about the negative impact that the continuously growing off-farm employment may have on China's goal to remain self-sufficient in grain production are less relevant at the moment for the region examined in our study.     

The impact of perceived security and consumer innovativeness on e-loyalty in online travel shopping

ABSTRACT

This study investigates the impacts of perceived security and consumer innovativeness on online travel shopping. A survey questionnaire was used to collect data and a total of 283 questionnaires were used for data analysis. The mechanism of perceived security and consumer innovativeness was then identified. The study results indicate that: (1) higher perceived security increases the perception of website image and trust; (2) consumers with a higher level of innovativeness tend to trust travel websites; (3) website image has a mediating effect between perceived security and trust; and (4) trust has a mediating effect between website image and e-loyalty.
