金融自由化、资源配置偏向与城乡收入差距——基于省级面板数据的经验证据

文章运用主成分分析法,重测了我国金融自由化指数值,同时采用31个省级面板数据,实证分析了金融自由化、资源配置偏向对我国城乡收入差距的影响。结果表明,金融自由化弱化了金融资源配置偏向对城乡收入差距的抑制作用;财政、固定资产投入偏向,均拉大了城乡收入差距;而FDI则一定程度上缩小了城乡收入差距。此外,金融自由化、资源配置偏向对城乡收入差距的影响,具有区域差异性。     

我国收入分配对消费需求的影响

现阶段我国收入分配差距不断扩大,具体表现在城乡之间、地区之间以及劳资之间。通过对社会总消费函数和人均消费函数进行非线性回归分析可以发现,社会总消费函数的边际消费倾向大大低于人均消费函数的边际消费倾向。收入分配差距造成了社会总消费函数的边际消费倾向对人均消费函数的边际消费倾向的大幅偏离。因此,要提高整个社会的边际消费倾向,必须努力缩小我国的收入分配差距,改善地区之间收入分配状况,加强收入再分配的调节作用。     

自然资源依赖对城乡收入差距的影响研究

［目的］针对全国31个省（市、区）（不含港澳台地区）、自然资源依赖度高的地区和自然资源依赖度低的地区,从整体和分区域研究自然资源依赖对城乡收入差距的影响,探究不同区域其影响程度的差异性,进而为弱化各区域城乡收入差距,解决由城乡收入差距拉大造成的各类社会矛盾具有重要的现实意义。［方法］从理论上分析了自然资源依赖对城乡收入差距的影响,并利用1999—2017年的省级面板数据,运用固定效应模型,从全国和分区域实证分析了自然资源依赖对城乡收入差距的影响。［结果］针对全国,自然资源依赖会拉大城乡收入差距; 分区域结果,针对自然资源依赖度高的地区,自然资源依赖拉大城乡收入差距; 针对自然资源依赖度低的地区,自然资源依赖对城乡收入差距影响不显著。［结论］为缩小城乡收入差距,需要降低经济体对自然资源的依赖,针对自然资源依赖度高的地区,政府通过将部分自然资源收益转化为农业创新基金和农村基础设施投入,促进自然资源收益向农村公共资本转化,完善现有的自然资源收益分配及转化制度; 鼓励资源型产业技术创新,加大研发投入,延长资源产业链; 加大农村教育投入、提升农村人力资本质量。     

Accounting for the Gender Technology Gap Amongst Smallholder Rice Farmers in Northern Ghana

Narrowing the gender technology gap in agricultural production has become a critical policy issue in sub‐Saharan Africa. A better understanding of the gender technology gap is essential for policy formulation and programme planning to ensure equity in resource allocation, and household‐level food security in low and middle income countries, such as Ghana. We employ a metafrontier approach to analyse the differences in the efficiency of male and female farmers, recognising the endogeneity of some of the variables in the inefficiency effects model, in particular the credit constraints of the rice farmers under study. Our findings show that while the rice farms themselves are very similar, average yields for male managed farms tend to be significantly higher than female managed farms reflecting higher seeding and fertiliser application rates on male managed farms. However, there is no significant difference between the genders in either land used for rice or total output per farm household. We find some evidence that relative to the metafrontier, male managed farms are less efficient than female managed farms. The results further show gender technology gap amongst the smallholder rice farmers with females’ technology gap ratio being significantly greater than that of males, with females operating on a production frontier closer to the metafrontier. Policies that provide females more access to productive resources and other agricultural services could assist in the generation of relatively higher output.

Further participatory adaptation is required for community leaders to champion conservation agriculture in Africa

There is a recognized need for the participation of local communities in designing and implementing agricultural interventions for the sustainable intensification in smallholder systems. This study examines the perspectives of local community leaders towards the widely promoted, but not widely adopted, practice of Conservation Agriculture (CA) in African smallholder systems. Perceptions from 47 community leaders (both from traditional local authorities and farmer organizations) across six African countries are documented regarding how CA matches the wants, needs and capabilities of farmers in their communities. While community leaders generally perceived CA as potentially beneficial, they also indicated that CA is not currently perceived as feasible within their communities and hence has limited relevance. Three key themes were identified that limit both CA use and sustainable intensification more generally: [1] a perceived reluctance of farmers to engage with the community platform as part of a higher input, market-oriented production system; [2] informational constraints due to non-functional exchange mechanisms; and [3] a lack of local adaptation of CA underscored by the persistence of top-down, linear research and extension approaches. Through greater understanding of local perspectives, a clearer picture emerges of the need for greater participatory engagement and local adaptation if sustainable intensification of African smallholder agricultural systems is to be achieved.     

Learning-by-importing in emerging innovation systems: evidence from Ecuador

Using data from the population of Ecuadorian importers, we examine the extent to which the characteristics of their imports relate to their labor productivity. Results indicate that the technological intensity of imports does not explain differences in labor productivity, although the region of origin of imports explains differences in the manufacturing sector, as imported technologies from advanced regions are associated with superior labor productivity. Nevertheless, as technology intensive imports are not associated with superior performance, we argue that importers from developing countries may use foreign technology inexpertly due to the lack of absorptive capacity and the emerging nature of their national innovation system.     

Technology gap,imported capital goods and productivity of manufacturing plants in Sub-Saharan Africa

This paper uses firm-level data from Ghana, Tanzania and Kenya to examine the effect of capital goods imports on domestic firms' productivity, and the role firms' technology gap plays in aiding the transmission of knowledge embodied in capital goods to domestic firms. The results show that increasing imports of capital goods and closing technology gaps have positive effects on productivity. Furthermore, domestic firms with technology standards farther from international best practices benefit more from capital goods imports. The results also imply that trade liberalization policy aimed at eliminating tariffs on capital goods will significantly improve the performance of technically incompetent firms in the African manufacturing sector.

Unethical use of wildlife in tourism: what's the problem,who is responsible,and what can be done?

Wildlife tourism is a huge global market, the revenue from which can promote local livelihoods and tourist education, enact conservation, and improve animal welfare. Such benefits arise if wildlife tourist attractions (WTAs) prioritise ethical deliverables above financial profit, but recent work has shown that the majority of WTAs have substantial negative animal welfare and conservation impacts. In the absence of global regulatory authorities, tourist revenue has become the ultimate arbiter of what constitutes acceptable use of animals in WTAs. Tourists, however, are not adequate assessors of WTAs’ animal welfare and conservation impacts: they lack the specialist knowledge required and are subject to a number of psychological biases that obscure the ethical dimensions of decisions to attend particular WTAs. This inadequacy is evidenced, and compounded, by overwhelmingly positive reviews on TripAdvisor (the industry-leading review site), even for WTAs with objectively poor ethical standards. Our suggested solution is to empower tourists by presenting unequivocal assessments of WTAs' animal welfare and conservation impacts, hosted in the fora that tourists already use to make their travel decisions. We would thereby promote a subjective norm that tourists should consider and limit their individual negative impacts when choosing which WTAs to visit.
