摘要：
The performance of Bt cotton in India is analyzed on the basis of field trial data from 2001. The amounts of pesticides applied during the trials were reduced to one-third of what was used in conventional cotton, while-under severe pest pressure-yield gains were 80%. Productivity effects are modeled econometrically with a damage-control specification. The first approval for the commercial cultivation of Bt hybrids was given in 2002. By 2005, the technology is expected to cover one-quarter of total Indian cotton area. Medium-term projections show sizeable welfare gains for the overall economy, with farmers being the main beneficiaries. (C) 2003 Elsevier Ltd. All rights reserved.
