High-dimensional covariates often admit linear factor structure. To effectively screen correlated covariates in high-dimension, we propose a conditional variable screening test based on non-parametric regression using neural networks due to their representation power. We ask the question whether...

Low-input production systems aim at mitigating agriculture's environmental impact with a lower level of chemical inputs. However, comparing the performance of low-input systems to conventional ones, particularly in terms of productivity and yield, is challenging due to selection bias. First, we...

This study employs panel data encompassing 31 provinces in China, spanning the period from 2010 to 2020, to investigate the distributional impact of foreign direct investment (FDI) on green innovation (GI). Employing a panel quantile regression model, the research finds the close association...
