保障性住房、社会身份与公平感*——来自社区实地实验的证据

2020年中央经济工作会议指出要重视保障性租赁住房建设，同时明确提出要逐步使租购住房在享受公共服务上具有同等权利。长期租购权利的不平等容易使得人们在心理认知上给予租房与购房不同的价值权重，这种认知上的差异进一步造成了租、购两类住户社会身份上的差异。因此，探究租购身份差异是否会影响人们日常交往时的公平感，对于改善人民居住条件，避免租购不同群体之间的社会分割，促进全体人民共同富裕有重要意义。为控制其他因素的干扰，我们运用实地实验方法，以同一社区的经济适用房住户和公租房住户为实验对象，以是否公开租购身份信息为干预手段，将租购身份外生地引入最后通牒博弈中，从自我认知和对他人的认知两个角度考察租购身份是否会影响租、购住户之间的公平分配行为。结果显示，公开租购身份会唤醒租房者的自我认知，长期的租购权利不平等使得租房者渴望更公平的资源分配。同时，公开租购身份也会改变人们对他人的认知，相比于面对购房者，人们在面对租房者时会提出更加公平的分配方案。     

顺北1号断裂带洞穴型储集体地震表征方法

顺北油气田1号断裂带奥陶系储层为碳酸盐岩断控缝洞型储集体，储集体在三维空间内差异较大，非均质性极强。1号断裂带以串珠地震反射特征为主，实钻证实储集体以洞穴为主，常规的波阻抗反演方法在刻画洞顶具有很好的效果，但是在刻画洞底和洞的宽度误差较大，不能精准刻画出洞穴的外轮廓，钻井轨迹设计靶点会出现偏差，钻进过程中不发生放空与漏失，需要酸压完井，增加完井成本的同时还有可能打出失利井，因此对该类储集体的有效识别和精细表征是油田增储上产的关键。基于正演模拟，针对串珠反射储集体开展了地震表征方法探索与地震属性敏感分析；对于串珠反射特征的洞穴型储集体，利用微分振幅与瞬时能量融合属性能够较好刻画顺北1号断裂带洞穴的顶底及宽度。实际资料的预测结果与实钻井特征吻合程度高，预测与实钻吻合率达89%，验证了顺北1号断裂带洞穴型储集体表征方法的可靠性。     

“双循环”场域特征下我国体育用品制造业的机遇、挑战与应对

借助 CiteSpace 软件工具，以中国知网收录的 CSSCI 来源期刊论文为数据来源，绘制知识图谱，对我国城市社区自治相关研究的基本情况、研究热点和研究发展态势进行可视化分析。研究结果表明，以我国城市社区自治为主题的理论研究虽未一直保持较高的增长率但总体发表量仍保持较高水平；研究主题主要涉及我国城市社区自治主体及其关系、当前自治过程中所面临的困境和相应的自治策略与模式的探索；我国城市社区自治的研究从宏观层面的自治思想研究逐渐过渡到微观自治问题的讨论，研究内容与国家政策和社会现状紧密结合，但研究预见性还有待加强，在党建引领、数据治理和服务创新等方面仍有较大研究发展空间。     

资本与地方发展的研究述评——基于发展地理与社会文化地理的整合框架

目前学界对于"资本"大致持两种研究视角,即将其视为一种生产要素或一种生产关系,由此,资本作用于地方发展的地理学研究也存在发展地理学和社会文化地理学两种对应的研究视角。随着关于地方发展的研究不断深进,两种研究视角逐渐非线性地交互作用,亟待在一个整合框架下提出新的综合范式,以推进地方发展研究的理论创新和实践分析。基于此,文章重新梳理了发展地理学和社会文化地理学两个学科视角下的资本与地方发展之间的相关研究,认为可以在场域空间视阈下将两个视角整合在同一个诠释框架之中,并基于该整合框架提出三个未来应关注的研究要点。文章的相关分析有利于推进当前中国发展战略的实施,且尝试提高中国人文地理学对于空间—区域发展问题的理论解释力。     

知识场活性、资源拼凑与新创企业创新绩效

基于对小微企业双创基地入驻企业的调查数据，构建出以知识场活性为自变量、新创企业创新绩效为因变量的概念模型，并将资源拼凑作为中介变量来分析。结果表明：知识场活跃度和知识场开放度均对新创企业创新绩效具有正向影响，资源拼凑具有中介作用；定制化服务对资源拼凑与新创企业创新绩效具有正向调节作用。研究结论丰富了“知识场活性→资源拼凑→新创企业创新绩效”这一逻辑主线的研究，对如何提升新创企业创新绩效具有一定的指导意义。     

What makes green persuasion effective? Evidence from a community-financed sanitation program in Indonesia

Understanding when and where face-to-face communication affects pro-environmental decisions is important for policymakers. We study a data set collected in a solicitation project intended to increase participation in a community-financed waste collection program in Indonesia. Two types of messages are developed and randomly assigned to 748 households. In addition, solicitors are randomly assigned to a control group or one of two treatment groups, and these groups are shuffled further midway through the project. These two orthogonal randomizations allow us to assess the impact of a combination of messages, solicitors and households. We find that the “help the children” message increases the probability of participation for households with a young child. Solicitor personality is associated with immediate participation but becomes nonsignificant after three months. Furthermore, a household is more likely to participate if a solicitor knows the respondent personally. These results suggest that, at least in the short term, important factors in encouraging behavioral changes include not only the contents of messages but also the type of sender of such messages. This paper highlights the possible impact of targeting and content-sender-receiver matching when persuasive communication is used as an environmental policy instrument.     

Do Jobseekers Value Diversity Information? Evidence from a Field Experiment and Human Capital Disclosures

We examine how information about the diversity of a potential employer's workforce affects individuals’ job-seeking behavior. We embed a field experiment in job recommendation emails from a leading career advice agency in the United States. The experimental treatment involves highlighting a diversity metric to jobseekers. Our results indicate that disclosing diversity scores in job postings leads jobseekers to click on firms with higher diversity scores, with such effects varying across jobseeker demographics. A follow-up survey provides evidence on potential explanations for why jobseekers value diversity information. We then examine how jobseekers’ preferences for diversity relate to disclosure choices under the U.S. SEC Human Capital Disclosure requirement. We find that firms in industries characterized by higher jobseeker responsiveness to diversity information tend to voluntarily disclose diversity metrics in their 10-Ks under these new disclosure requirements.     

Building smallholder farmers' capacity to adopt climate-smart agricultural practices in flood prone areas: Lessons from Bangladesh

Currently, there is an increased interest in promoting climate-smart agricultural practices (CSAPs) around the globe, however, application of these practices may vary for different climate risk hotspots. Although, climate field schools (CFS) are conducted with the aim of empowering farmers with knowledge on the various agricultural practices, little attention has been devoted to building the capacity of smallholder farmers to facilitate adoption of appropriate CSAPs. Given the effects of climate change on agriculture, it is fundamental for agricultural sustainability to answer the question that has hardly benefited from empirical analysis in previous land use studies, which is: Do CFS build farmers' capacity to adopt CSA in flood prone areas? Cross-sectional data from 600 rural farm households in south Bangladesh is used and the recursive bivariate probit (RBP) is applied to address this knowledge gap. The results reveal that participation in CFS increases the probability of a farmer's soil salinity consciousness by 25% and eventually improves the probability to adopt climate-smart agricultural practices by 20%. We also analyzed the spillover effects of CFS participation on CSA adoption and found that there is a strong spillover effect which has important implications on the cost effectiveness and sustainability of the program. Overall, the study provides empirical evidence demonstrating that participatory approaches stimulate adoption of appropriate CSAPs by building farmers' capacity in recognizing the existing climate risk hotspots.
