北京地区月季综合评价体系的建立

对4个类型的月季(茶香月季、丰花月季、藤本月季和微型月季)，共计238个品种的植株性状、花部性状和抗性等27个性状进行详细观测，结合月季在北京园林绿化中的应用形式，利用主成分分析方法，筛选出了13个性状指标。以准确筛选适合北京地区栽植的新优月季品种为目标，基于植株性状、花部性状、和抗性3个层面，利用层次分析法，分别构建了针对四大类群月季的综合评价体系。应用该评价体系，筛选出综合性状优秀的杂交茶香月季品种20个、丰花月季品种11个、藤本月季品种3个、微型月季品种8个。为今后合理筛选适宜北京地区栽植的月季品种提供了一条有效的途径。     

Impact of Outward Foreign Direct Investment on Chinese Manufacturing Firms' Financialization and Servitization

This study examines the impact of outward foreign direct investment (OFDI) on Chinese manufacturing firms' financialization and servitization. Using a difference-in-differences approach with propensity score matching, we found that OFDI encouraged firms' financial and service activities. The effects of OFDI on financialization were stronger for firms specializing in short-term financial assets, operating in labor and technology-intensive sectors, investing overseas to pursue production, resources and markets there, and investing in non-OECD and Belt and Road Initiative (BRI) countries. Meanwhile, firms investing overseas were more likely to provide services at the sale or postsale stages. Outward foreign direct investment has also boosted the service activities of firms operating in the technology-intensive sector by investing overseas to seek resources and markets, as well as investing in non-OECD and BRI countries. Finally, OFDI partially influenced the extent of financialization and servitization of firms by affecting their profit-making ability.     

乡村振兴背景下河南省农业供应链应收账款融资发展研究

基于河南省4个省辖市农业供应链应收账款融资情况,研究发现,农业供应链应收账款融资整体呈全产业链发展态势;传统农业生产企业规模占比较大;质押模式为主,线上业务发展良好;跨区域融资缓解了异地厂商融资难;试点城市发展明显优于非试点城市.但也存在一些问题,如企业债务困境制约应收账款融资发展;贴合需求的金融服务和金融产品较少;农村金融机构服务农业供应链能力偏弱;农业供应链应收账款融资推进缓慢等.对此建议,以企业品牌为支撑提高战略发展水平,以创新为抓手探索应收账款融资新模式,以资产盘活为重点助力金融机构增强实力,以规范为标尺推动融资模式的建设和应用等.
