Firm Innovation Under Trade War: The Rise in Quantity and the Imbalance in Quality
主讲人:
陈泽 博士生
摘要:
This paper investigates why China’s systemic innovation policies underperformed during the U.S.-China trade war, focusing on firm responses to policy incentives. Using tariff lists matched with export data from Chinese listed firms, we measure trade war exposure and apply a difference-in-differences analysis. Results show that while the total number of patents increased by 10.1%, this growth was driven by an 18.4% rise in incremental patents, with no significant change in breakthrough patents. To offset reduced profits, higher costs, and increased trade uncertainty, firms prioritized incremental patents to secure government subsidies, access bank loans, and improve capital market performance. These findings highlight how quantity-based innovation policies incentivize opportunistic behaviors, increasing government burdens without enhancing firms’ resilience or competitiveness under external shocks.

Government Innovation Targets、End-of-year Patenting Rush and Innovative Bubbles in Chinese Agricultural University
主讲人:
王海军 博士后
摘要:
Many governments set innovation targets, but few studies have assessed the policy impacts of these targets. Agricultural universities in particular, as a core part of the innovation system, are usually expected to meet targets that the government sets. Thus, the following question arises: do government-set innovation targets encourage agricultural university innovation? To answer this question, we manually collected data on research and development (R&D) investment targets from 3091 work reports of Chinese city-level governments and obtained patent data from 813 universities from 2007 to 2017. Employing quasi natural experimental methods and a dual machine learning approach, we explored how innovation targets set by local governments impact agricultural university innovation outputs and identified a few key underlying mechanisms. Notably, we present novel evidence that innovation targets lead to more innovation but have no significant effect on quality. We refer to this phenomenon as "innovation bubbles." The mechanism found that the government's innovation targets led to the agricultural universities' end-of-year rush to apply for patents, thus creating an innovation bubbles. Moreover, while targets that deviate from actual endowments do not increase the number of innovations in universities, continuous government innovation target setting can increase the number of innovations in universities.

中国家庭居民收入流动性：结构性分解、区域差异与动态演进——基于2010—2022年CFPS数据的微观证据
主讲人:
林立 博士生
摘要：
增强居民收入流动性是防止家庭收入阶层固化的重要表征。本文利用中国家庭追踪调查（CFPS）2010—2022年共7轮调查数据，在主要使用收入转移矩阵，结合惯性率、Shorrocks指数、平均流动指数和向上/向下流动比率等指标测度和分解了家庭人均纯收入及四项结构性收入流动性水平的基础上，然后使用Kernel密度估计和区域间基尼系数分别从全国和地区层面全面分析了中国家庭居民收入流动性的区域差异及动态演进趋势。研究发现，中国家庭居民收入流动性水平总体呈稳步下降态势，这表明自2010年以来家庭居民收入流动呈现相对固化现象；结构性收入的流动性水平总体上呈现“财产性收入>经营性收入>转移性收入>工资性收入”的局面；西部地区的低收入阶层和高收入阶层的转移概率高于中部地区和东部地区；农村地区的低收入阶层和高收入阶层的转移概率均高于城镇地区；区域间的家庭居民收入流动性绝对差异呈现明显缩小的趋势。
