题目一：The Brazilian Model to Feed the World: Implications for China

摘要：In just over fifty years, Brazil moved from being a net-importer of food to the world’s largest agricultural exporter. This talk analyzes the key drivers and consequences of that process by focusing on what I call the “Brazilian model to feed the world”. The model of Brazilian agriculture is considered in relation to the broader globalization of agriculture and, in particular, how the Brazilian model benefitted from the global circulation of agricultural technologies and the emergence of lucrative markets for key commodities. I will present empirical data on the evolutionary development of Brazilian agriculture by drawing on those two cases of soybeans and beef as illustrative examples. Lastly, I will analyze the implications of the Brazilian model to feed the world for food security and economic development in China. This analysis will center around the analytical categories of: scale and integration; inequality and equity and; environmental sustainability.

题目二：Impact of specialized agricultural services on the adoption of biopesticide: Evidence from Jiangsu Province of China

主讲人：邹凯，博士生

摘要：Pesticide residue is emerging as a worldwide issue with a great threat to the ecological environment, human health, and sustainable use of cultivated land. The promotion of biopesticides, environmentally-friendly substitutes for chemical pesticides, shapes an irresistible but tortuous trend. By using panel data of 3143 rural households from 2020 to 2021 in Jiangsu Province, this paper builds a theoretical framework of whether and how specialized agricultural service (SAS) for specialized pest control affects farmers’ biopesticide application, and then employs an Endogenous Switching Probit model to verify this effect and its channels empirically. The empirical results show that the SAS purchase can increase significantly the probability of smallholders’ biopesticide adoption by 30.8 percent. Without consideration of the self-selection bias, this probability would drop to 16.2 percent. The potential channels of the SAS influencing farmers’ biopesticide application are technology popularization (training) and machinery substitution resulting from SAS. Moreover, our findings also indicate that the effects of SAS on biopesticide adoption are heterogeneous, and vary with farmers’ education level, the identity of cooperative members, and land size. Generally, this paper provides the first empirical evidence for the effect of SAS on biopesticide promotion, which is expected to contribute to agricultural sustainable development and food safety in most developing countries.

题目三：电子商务对县域内城乡收入差距的动态影响——来自农村电子商务综合示范政策的经验证据

主讲人：秦秋霞，博士生

摘要：发展电子商务是中国乡村振兴战略的重要举措，而电子商务发展能否真正有效地惠及农民病缩小县域内城乡收入差距？在理论分析的基础上，本文基于2011-2018年全国县域面板数据，考察了在电子商务进农村综合示范政策下，电子商务发展对县域内城乡收入差距的影响。研究发现，电子商务示范县政策使县域内城乡收入差距显著缩小3.5%，且电子商务示范县政策实施年限对县域内城乡收入差距产生非线性影响，即电子商务政策实施对县域内城乡收入差距产生“倒U型”影响，初期会扩大城乡收入差距，而在实施2-3年后开始缩小城乡收入差距。电子商务示范县政策对县域内城乡收入差距的动态影响存在地区间的异质性。机制检验结果表明，电子商务示范县政策导致其非农就业水平、产业规模化程度先减后增，且非农就业水平、产业规模化程度在电子商务示范县政策对县域内城乡收入差距的影响中发挥部分中介效应。本研究为电子商务发展促进中国乡村振兴、实现共同富裕提供了有力的经验证据支持。
