新基建发展对产业升级的影响机制研究

新基建作为现代化基础设施体系的重要组成部分，已经成为中国经济高质量发展的重要支撑。基于2015—2021年中国71个城市的面板数据，构建双向固定效应、中介效应和调节效应三种回归模型，实证检验新基建发展对城市产业结构水平的影响及内在机制。研究发现：新基建发展能促进产业高级化水平，改善不合理的产业结构状态，提升产业合理化水平；新基建通过发展物联网和激励城市研发创新两种间接路径对产业结构转型升级产生积极影响；新基建对产业结构水平的影响受到地方政府干预行为的调节作用，在地方政府合理的行政管理下，新基建对产业转型升级的积极作用更为明显；新基建发展对产业结构水平的提升作用具有区域异质性和城市规模异质性，在中西部地区和大城市地区的作用效果更为明显。     

土地市场扭曲如何影响制造业出口产品质量升级*——基于土地市场交易数据和制造业企业数据的实证分析

地方政府“以地谋发展”的策略在促进各地区制造业大规模集聚和出口贸易快速增长的同时，也势必会给企业出口产品质量带来深刻影响。本文综合利用中国土地市场网城市土地交易数据、中国工业企业数据、中国海关进出口产品数据和中国城市面板数据，实证检验了土地市场扭曲对企业出口产品质量升级的影响，并对其内在机制进行了探讨。研究发现：中国城市建设用地配置存在明显的工业偏向性，进而导致工业用地价格被低估，产生工业用地应得收益大于实际价格的反向扭曲问题。这种反向扭曲可通过抑制技术进步、阻碍产业结构高级化、弱化集聚经济效应等机制显著降低制造业企业出口产品质量。土地市场扭曲对企业出口产品质量升级的影响具有明显的异质性特征。具体而言，土地市场扭曲不利于一般贸易企业与混合贸易企业出口产品质量提升，但对加工贸易企业出口产品质量提升具有促进作用。土地市场扭曲对企业出口产品质量升级的抑制作用由东到西依次递增。土地市场扭曲不利于外资企业和国有企业出口产品质量提升，对集体企业及民营企业的影响不显著。     

“绿色矿业”的逻辑机理、实践探索与推进策略

发展“绿色矿业”是人类进入生态文明社会的必然选择，绿色发展理念指导下的“绿色矿业”发展具有主旨统一性和实践多样性、国家主导性和企业渐进性，需要完善的理论指导、体系构建和政策支持。“绿色矿业”的运行体系是由相关主体（绿色政府、绿色企业、绿色社会、绿色市场）及其功能共同形成的网络结构，各主体多元化、多维度的相互作用共同促进“绿色矿业”的有序发展，最终实现“矿业经济发展、生态环境良好、发展成果共享”的目标。我国发展“绿色矿业”的实践取得了显著成效，各地不同的发展模式既有目标的同一性，又有方式的差异性。当前，我国“绿色矿业”发展还存在标准体系不健全、政策法规不完善、发展格局不协调、协同监管不到位等问题，需要进一步发挥政府的主导作用、企业的主体作用、行业协会及社会的协调支撑作用，并构建和优化“绿色矿业链”和“绿色矿业区域板块网络”，推动“绿色矿业”健康有序发展。     

Measuring Farm and Market Level Economic Impacts of Improved Maize Production Technologies in Ethiopia: Evidence from Panel Data

While it is often recognised that agricultural technology adoption decisions are intertwined and best characterised by multivariate models, typical approaches to examining adoption and impacts of agricultural technology have focused on single technology adoption choice and ignored interdependence among technologies. We examine farm‐ and market‐level impacts of multiple technology adoption choices using comprehensive household survey data collected in 2010/11 and 2012/13 in Ethiopia. Economic surplus analysis combined with panel data switching endogenous regression models are used to compute the supply shift parameter (K‐shift parameter), while at the same time controlling for the endogeneity inherent in agricultural technology adoption among farmers. We find that our improved technology set choices have significant impacts on farm‐level maize yield and maize production costs, where the greatest effect appears to be generated when various technologies are combined. The change in maize yield and production costs results in an average 26.4% cost reduction per kilogram of maize output (the K‐shift parameter). This increases the producer and consumer surpluses by US$ 140 and US$ 105 million per annum, respectively. These changes in economic surplus help to reduce the number of poor people by an estimated 788 thousand per year. We conclude that deliberate extension efforts and other policies that encourage integration of technologies are important for maize technologies to yield their full potential at both farm and market levels.     

Business marketing in France: can the case be made for “French exceptionalism” or is it just a slight variation?

Purpose: The aim of this article is to elucidate the state of B-to-B marketing research in France by conducting a review of theoretical and empirical studies in this field that have been published over the last three decades.

Methodology/approach: Authors identified relevant literature sources, and proceeded with classifying the publications according to their main theme of study (as determined by reviewing the topic, the abstract, and/or keywords). To extract the main articles, authors explored multiple electronic databases, including Source Premier (EBSCO), Elsevier Science Direct, Google Scholar, and Cairn.info. This methodology has allowed comparisons both in time and in relation to similar works done in other countries. The analysis focuses on the main contributions of French literature in the B-to-B domain and establishes that progress has been made in understanding the issues of B-to-B marketing in France, as well as in the development of the theory in this field.

Findings: The review shows that B-to-B marketing research in France, although under-represented in relation to its B-to-C counterparts, is gradually emerging from the shadows and covers important topics that are increasingly diverse and varied. By identifying the main topics studied by French B-to-B marketing researchers, this work advances this academic discipline while also providing valuable information.

Originality/value: This study is the first attempt to conduct an in-depth examination of the state of B-to-B marketing research in France. Findings yielded by this literature review would be beneficial to both B-to-B marketing researchers and practitioners and promotes this research field.     

普惠金融与县域资金外流：减贫还是致贫*——基于中国592个国家级贫困县的研究

本文利用全国592个国家级贫困县的数据，采用空间计量模型实证分析了普惠金融对县域资金外流的影响，并验证了贫困县资金外流是否会产生致贫效应。本文研究发现：如果普惠金融只注重解决贫困地区对金融机构的接触性排斥，会进一步加剧资金外流，对减贫产生负向影响，即存在显著的致贫效应。这种致贫效应具有明显的空间外溢性，邻近县域的贫困状况在很大程度上会彼此“传染”，并具有空间衰减特征的地理边界。因而需要客观认识普惠金融的本质，有针对性地选择恰当有效的实施载体，解决好对信贷产品等关键金融服务的使用性排斥问题。

FDI and Welfare Dynamics in Africa

This article examines the welfare impact of foreign direct investment (FDI) in a panel of 20 African countries over the period 2000–2013. We explore the multifactor and nonmonetary measures of welfare and the nonlinear effect of FDI on welfare. We used the Driscoll and Kraay standard errors and augmented mean group (AMG) estimator by Eberhardt and Teal (2010) to account for cross‐sectional dependency, endogeneity, and heterogeneity within panel units. The results indicate that although FDI is welfare enhancing, the nonlinear terms report mixed findings. When a multifactor indicator is employed, the increase in the nonlinear term is lower than the linear part. However, there is strong evidence that FDI is ultimately welfare enhancing when a nonmonetary indicator is employed. From an international business perspective, the findings have unlocked the welfare effects of international business on African host economies. International businesses through FDI can enhance welfare in Africa countries. However, the optimal efficacy of FDI‐welfare impact differs across the various dimensions of welfare. © 2017 Wiley Periodicals, Inc.     

Who benefit from government-led microfinance projects? Evidence from rural China

Drawing from a unique dataset of 2356 Chinese villages, this paper assesses the anti-poverty effect of the largest government-led microfinance project in the developing world. We find that the project can significantly increase the income level in the targeted villages. The main engine of the project lies in the expansion of access to nonfarm activities. We also highlight the importance of institutional circumstance in the effectiveness of the project. Specifically, a more democratized village with less political connection to local governments reaps more benefits from its participation.
