乡村振兴战略下要素国际流动的环境效果

乡村振兴战略和环境保护是当前经济工作中的重点。伴随经济全球化和“一带一路”战略的不断深入,生产要素国际流动日趋频繁。乡村振兴是国家重要发展战略,其重要抓手是实现农业现代化。因此,在小农户与现代农业共存的经济背景下,分析要素国际流动的环境效果,并根据现代农业发展的不同特征,对乡村振兴战略实施初始阶段和全面实施阶段分别进行分析后发现:在战略实施初始阶段,劳动流入加剧污染,反之改善环境;在战略全面实施阶段,资本流入改善环境,反之恶化环境。     

城乡炫耀性消费差异的根源探索

运用中国家庭追踪调查数据,研究发现:农村家庭的炫耀性消费支出比例显著高于城镇家庭,且这一结果随时间变化比较稳健。进一步研究发现,在考虑了家庭参照群体的平均收入之后,城乡炫耀性消费差异不再显著,且参照群体的平均收入对家庭炫耀性消费的影响显著为负。这很可能来源于家庭为寻求社会地位而消费的动机,更高的社会地位意味着更多的财富和带来更高的收益。炫耀性消费充当了家庭社会地位的信号,向其参照群体传递了自身的收入水平状况,参照群体的平均收入越低,消费者寻求社会地位的消费动机越强。农村家庭参照群体的平均收入较低,所以其寻求社会地位的动机更强、炫耀性消费水平更高。因此,寻求社会地位的消费动机是城乡炫耀性消费差异的主要原因。

Research on a diagnostic system of rural vitalization based on development elements in China

In 2017, the Chinese government implemented a national strategy of "Rural Vitalization" that sought to realize full-scale rural vitalization. However, is it possible to achieve vitalization for all the villages in China? How should their development potential be determined? This paper identified and analyzed the "element-composite" messages of rural development based on 99 exemplary sites of “Beautiful Villages” in China. Combined with the projection pursuit classification method, a diagnostic system of rural vitalization was established; then, Dehua County was taken as a case study for an in-depth analysis. Based on national data analysis, the final results indicated that livelihood resources (LR), agglomeration effects (AE), location and transportation (LT), cultural/natural landscapes (CN), and economic circumstance (EC) are essential elements for successful rural development. Additionally, EC was the only exogenous element, while the remaining elements were endogenous. Furthermore, the villages with better EC presented urbanization rates of 38∼82 % and Engel coefficients of 29∼41 % in their counties; exemplary sites lacking LR, CN, LT, and AE account for 13.13 %, 19.19 %, 26.26 %, and 60.61 % respectively, so the indispensability of these elements decreases progressively in sequence. Only 2 % of villages rely on single element for success, therefore, the composite pattern of development element was also critical; 10 out of 16 types were found to successfully facilitate village development, among which, the type of R-a-L-C (32.32 %) and R-A-L-C (15.15 %) were considered as the greatest potential patterns for vitalization. Finally, by means of the diagnostic system, the ratio of representative villages for high-low potential in Dehua County is evenly split; then, development paths, and land use policies that match with paths were proposed, on the basis of development potential and “element-composite” condition of themselves.     

The trade-offs between economic efficiency and job creation in olive grove smallholdings

Cooperation among farmers is an effective alternative to reduce production costs in smallholdings of traditional olive groves and increase their low profitability. However, an increase in efficiency reduces working hours and the labour required for the management of farms. This fact can lead to negative effects in rural areas, especially considering the importance of the social aspect of the crop. Therefore, to contribute to the global discussion on the transition towards more sustainable farming, it is important to know, ex ante, what level of employment is generated by olive groves and what could be lost under more competitive and efficient scenarios. The purpose of the work is to quantify the expected impact on employment by the implementation of cooperative management methods in order to generate true and accurate information that can be used in the design of future policies that aim to increase the economic profitability of small olive farms. The results make clear that this way of managing farms, by increasing the efficiency of agricultural work, has a significant negative impact on employment. However, this management formula does encourage the professionalisation of the sector by generating quality employment, in addition to contributing to the preservation of small farms and the socio-cultural and territorial benefits they generate.     

Rural Residential Land Transition in the Beijing-Tianjin-Hebei Region: Spatial-Temporal Patterns and Policy Implications

Rural residential land transition (RRLT) dominates rural land use transition. Therefore, analysing the laws of transition and differentiation of land use is not only the basis for the differential management of rural residential areas but key to the sustainable use of rural land. This study constructs a conceptual model of RRLT using multi-period remote sensing monitoring data based on a comprehensive index method, ArcGIS, and FRAGSTATS landscape pattern analysis, among others. It also analyses the characteristics of the transition extent, transition trend, transition morphology, and transition intensity of rural residential land in the Beijing-Tianjin-Hebei (BTH) region from 1980 to 2018. The results show that, from a vertical comparison of long time series, the transition extent is characterised by a process of ‘slow growth—expanding start—fast expansion—slowing down’; the transition trend is characterised by an increase in the amount of cultivated land occupied by rural residential land, followed by a large number of rural residential land is reclaimed as cultivated land; the transition morphology is characterised by an increase in mean patch size and degree of irregularity, as well as aggregation; and the transition intensity is characterised by fluctuations in the process of ‘small-scale reduction—small-scale growth—substantial growth—small-scale growth and reduction’. A horizontal comparison of counties in the BTH region reveals a long-lasting and active growth trend in transition extent and transition intensity in the Beijing-Tianjin region, and a gradually slowing trend in the areas around the region. The transition morphology features of the northwest Hebei region are more prominent, and show that the scale of rural settlements is small, the plaques fragmented and irregular, and the layout more scattered. The BTH region should formulate a differentiated transition direction for rural residential areas based on the different functional areas, and play into the agglomeration, scale, and synergy effects of urban agglomerations. It should also coordinate and improve the human–land relationship in rural areas, and construct an orderly and densely distributed pattern of urban and rural spatial development with a reasonable layout and complementary functions.     

农村劳动力流动对脱贫的影响文献综述

关于农村劳动力流动与贫困之间的关系一直是社会各界广泛关注的焦点。本研究通过对相关文献的梳理，针对劳动力外出务工的减贫效应，从贫困缓解论、贫困加剧论以及不确定论三方面进行概述，重点分析劳动力流动对我国农村贫困的影响及机制。结果表明，农村劳动力外出务工通过提高农户非农收入和改善整个社会的资源配置效率在收入维度上对农村贫困具有一定减缓作用，但同时，受农村劳动力过量流失的影响，外出务工在农户生活照料及社会保障等多维贫困上并未表现出显著作用，甚至存在一定负面影响。因此，应把握好劳动力外出之度，促进劳动力就近就业，同时加强对农村留守人员的社会保障，以实现多维脱贫、乡村繁荣。     

Employment Dynamics and Linkages in the Rural Economy: Insights from Senegal

Evidence on rural wage employment is thin and lacks nuance for different employment sources, insights on dynamic effects, and an understanding of the channels of effects. We assess conceptually and empirically the direct and indirect welfare effects of entry and continuation in different types of wage employment in rural Senegal. Using panel data, fixed effects and first-difference estimation, we show substantial positive welfare and linkage effects. We find that participation in wage employment increases per capita income by 143%, and reduces poverty, poverty gap and food insecurity by, respectively, 63%, 89% and 48%. While the direct effect on income is larger for non-agricultural and contractual wage employment, the indirect income effects through self-employment are more pronounced for agricultural and casual wage employment. Our results imply that job creation is important for rural development, that wage employment in agriculture can lead to considerable growth multiplier effects, and that synergies exist between large-scale and small-scale agriculture.     

制度变迁下国有商业银行农村服务网络演化——以农业银行兰考县支行为例

经济转轨背景下农村的银行服务网络呈现出不同于城市的演化特征。从制度变迁角度建构分析框架,基于历史、调查与访谈数据,以农业银行兰考县支行为例,探讨我国商业银行农村服务网络演化动力机制。研究表明:国有商业银行农村服务网络经历了恢复成立后的快速扩张和密集的人工网点服务,市场化改革中农村业务收缩和大规模网点撤并,到新时期人工、自助、电子、代理等多元服务渠道扩张;农村银行服务网络演化是商业银行和制度环境相互作用的空间过程,普惠金融战略下我国特别强调金融服务的均等化和基础金融网点的全覆盖,商业银行不断借助新的伙伴关系开拓农村市场,其中合作代理日益发挥重要作用。不同地区、不同商业银行农村服务网络模式的差异,农村银行服务网络转型对农村社会经济发展、金融生态环境改善、农民金融素养提升的影响等还需进一步研究。     

旅游产业与农村可持续生计耦合的空间格局及驱动机制——以张家界为例

通过构建乡村旅游与农村可持续生计系统指标体系,运用变异系数和耦合协调度模型对2005—2018年张家界乡村旅游与农村可持续生计的耦合度和协调度进行测算,分析耦合协调度的空间格局,并运用地理探测器方法对其驱动机制进行分析。研究表明:①2005—2018年耦合协调度保持连续上升的趋势;②乡村旅游发展初期呈现东部高西部低的分布格局,中期呈现东南部滞后于西部的分布格局,但最终张家界整个区县达到优质协调;③耦合协调度空间分异的主要影响因素有人均GDP、旅游收入占GDP比重、农业机械化水平和人均财政收入等,且具有明显的时间异质性特征。
