农业绿色发展模式的农业保险需求引致效应——基于荔枝种植户的经验分析

目的 研究农业绿色发展模式引致的农业风险规避需求及其特点,提出完善和推广农业保险、推进农业绿色发展的政策启示。方法 文章将农户农业保险需求分为5个等级,以采用生物防控和非化学生长调节技术来衡量农业绿色发展模式,然后构建排序Logit模型,利用2018—2019年国家荔枝龙眼产业技术体系的调查数据证明农业绿色发展模式和农业保险需求之间引致效应,并借助OLS、2SLS、LIML和分位数回归法检验了模型的稳健性。结果 （1）排序模型中农业绿色发展模式的系数均在1%的显著性水平上显著,说明农户的农业绿色发展模式会引致显著的农业保险需求,年龄、种植经验、合作组织、种植规模的系数也显著不为0,体现出种植规模较大、种植时间较长、参加合作组织的非老年人农户对农业保险需求影响较明显;（2）0.50分位数回归的农业绿色发展模式系数值最大,表明农业绿色发展模式引致的农业保险需求往往处于中等水平。结论 政府政策应充分考虑和满足农户农业绿色发展模式中的风险规避需求,才能深入推进农业绿色发展;而促进农业绿色发展的农业保险费率标准与推广策略也需要充分考虑农户种植规模、种植经验、合作组织、农户年龄和中等水平的农业保险需求等因素。     

浙江省农户获得贷款影响因素的实证分析

利用317份浙江农户调查数据,采用二元Logit模型研究了影响农户是否获得贷款(贷款意愿)的因素。发现城郊农户更倾向于贷款;年龄越大,农户越不倾向于贷款;农业收入越多,越倾向于贷款;参加合作社的农户比不参加合作社的农户更倾向于贷款。从影响程度看,农业收入对农户是否贷款决策的影响大于年龄的影响。性别,教育年限,是否外出打工,劳动力数量,学生人数,总收入,总面积,主要收入来源是否为农业等变量系数不显著。     

An experimental study of costly coordination

This paper reports data for coordination game experiments with random matching. The experimental design is based on changes in an effort-cost parameter, which do not alter the set of Nash equilibria nor do they alter the predictions of adjustment theories based on imitation or best response dynamics. As expected, however, increasing the effort cost lowers effort levels. Maximization of a stochastic potential function, a concept that generalizes risk dominance to continuous games, predicts this reduction in efforts. An error parameter estimated from initial two-person, minimum-effort games is used to predict behavior in other three-person coordination games.     

通道货运分担率预测的LOGIT模型特性变量选取

文章基于效用函数理论和Logit模型,结合影响通道内各种运输方式选择的影响因素分析,以及各种运输方式的特性,认为通道内影响货运分担率预测的特型变量选取了安全性、快速性、用户成本、方便性、准时性以及货物价值6个特型变量,并分析了各个特性变量的的取值标定方法。     

中小城市居民对生鲜蔬菜零售终端的选择行为研究——基于排序多元Logit模型的实证分析

随着经济的不断发展,超市逐渐成为消费者购买生鲜农产品的重要场所。文章利用对山东省烟台、潍坊、济宁、临沂四市510名消费者的问卷调查数据,运用排序多元Logit模型,深入分析了影响消费者选择生鲜农产品零售终端的各种因素。研究结果表明,家庭人均收入、零售终端的净距离及消费者对价格和质量的偏好程度对消费者零售终端的选择有显著的影响。根据研究结论,认为蔬菜的三种零售终端在未来较长的时间内将长期并存,在对农产品零售终端进行布局规划时要充分考虑经济距离的合理性,同时对农产品零售终端的升级改造要采取循序渐进的原则。     

中国对外反倾销影响因素研究

利用1999-2009年中国对外反倾销申诉数据,本文运用Logit模型和经典线性模型,实证测量了行业企业单位数、全部从业人员年平均数、总资产贡献率、资本密集度、工业成本费用利润率、竞争力指数、进口渗透率,对中国对外反倾销行为在发起阶段的影响程度,提出行业企业单位数、总资产密集度和进口渗透率是发起反倾销申诉的重要影响因素,进口渗透率和全部从业人员年平均是影响申诉频率的主要因素。     

政治风险规避与中国企业的 OFDI 策略选择

政治风险已经成为中国企业对外直接投资(OFDI )遭受损失最重要的原因之一,但是企业可以通过选择合理的投资策略来规避风险,降低损失。文章基于2004－2013年?中国境外投资企业(机构)名录?提供的 OFDI 企业数据,利用二值选择模型、倾向得分匹配(PSM )法和条件 Logit 固定效应模型分别考察了我国企业面临东道国政治风险时的策略选择问题以及投资经验对政治风险的调节作用。结果发现：东道国政治风险越高,企业越倾向于采取序贯式投资,投资经验可帮助企业规避和降低部分政治风险,提高企业在高政治风险东道国 OFDI 的概率;与生产性 OFDI 企业相比,销售宣传类 OFDI 企业对东道国政治风险的反应弹性较大,在具备投资经验后,对政治风险的敏感性降低。文章为中国企业“走出去”过程中如何有效地规避东道国的政治风险和提高成功并购的概率提供了有益的思路和借鉴。     

Business group affiliation and SMEs’ international sales intensity and diversification: A multi-country study

This study examines the impact of business group (BG) affiliation on international sales intensity and diversification in small and medium-sized enterprises (SMEs) by using a multi-country sample of over 13,000 SMEs from 34 European countries. Drawing on the revised Uppsala internationalization model and network theory, this paper suggests that the effects of BG affiliation on international sales intensity and diversification depend on the geographical dispersion of the BG network ties, the size and the age of the firm, and the institutional support in the home country. Thus, we find that interfirm networks in the form of BGs are a double-edged sword that can have both favorable and unfavorable consequences for international sales, depending on the geographical dispersion of the BG’s ties. In addition, the results reveal that BG affiliation is more beneficial for smaller SMEs and SMEs in countries with lower institutional support that are more dependent on the network resources embedded within BG networks.     

Influences of consumer characteristics on fairness perceptions of revenue management pricing in the hotel industry

Fairness perceptions play an important role in customers’ behavior, and this study explores which consumer characteristics influence fairness perceptions of revenue management (RM) pricing in the hotel context. To examine such differentiating characteristics, the study conducts a logit analysis by comparing two groups: one group of customers who consider hotels’ RM practices to be fair and the other group considers the practices to be unfair. The findings provide an opportunity for hotel managers to identify customers’ particular characteristics that affect customer's perceptions of the fairness of hotels’ RM pricing practices.     

Capacity retirement in the dry bulk market: A vessel based logit model

The paper investigates the effect of vessel specific and market variables on the probability of scrapping dry bulk ships. Using a dataset from 2012 to 2015, we find that the probability of scrapping increases with age, but that the relation between vessel size and scrapping probability varies across the different segments. In addition, while the relation between earnings and probability of scrapping ships is negative, bunker prices seem to affect only the scrapping rate of smaller tonnage. Scrapping probability also increases with an increase in interest rates, freight market volatility and scrap steel prices.
