Effects on green production technology adoption on high-quality development of Zhangqiu onionwith moderating variables of operating scale and human capital

Based on survey data of 124 onion growers in Zhangqiu District, Jinan City, Shandong Province, an integrated model of technology adoption, moderating variables and high-quality development was constructed, to explore impact mechanism of green production technology adoption on Zhangqiu onion's high-quality development and test moderating effects of operating scale and human capital．Results showed that green production technology adoption significantly promoted Zhangqiu onion's high-quality development．Operating scale had a negative moderating effect on impact of green production technology, with scale expansion leading to diminishing marginal benefits．Human capital had a positive moderating effect on impact of green production technology．Among control variables, risk preference and irrigation conditions had a significant positive impacts on high-quality development, while age and cooperative participation exhibited negative effects．Based on these findings, it was suggested to build a trinity promotion system integrating demonstration-training-subsidy, implement differentiated scale operation management policies, and strengthen human capital cultivation mechanism．
