货币政策、企业家信心与上市公司投资效率*

企业、企业家等微观主体对货币政策的反应，在较大程度上影响货币政策的效果。货币政策可通过对企业家信心的影响，进而对公司投资效率产生作用。基于中国2007—2016年40个季度A股上市公司样本的实证研究表明：企业家信心在货币政策传导过程中有不可忽视的作用。企业家信心增强或者货币政策宽松时会加剧过度投资，减轻投资不足；企业家信心减弱或者货币政策紧缩时可以有效抑制过度投资，但会加剧投资不足。其中，国有企业对企业家信心和货币政策松紧的敏感性更强。进一步，货币政策对企业投资效率的影响，也会通过货币政策和企业家信心的交互作用而发挥作用。这种作用在国有企业和非国有企业之间无显著差异。     

国有林场改革成效评价——职工获得感的统计分析

利用国有林场职工监测数据,基于物质维度和精神维度,从改革后职工自身的收益情况、职工对林场的整体评价、职工对林场管理方式的评价等方面,采用比较分析法和主成分分析法对国有林场改革职工获得感进行分析。研究结果表明:国有林场改革后职工获得感有所提升,改革进程与职工获得感呈强正相关性,改革促进了林场的可持续发展。但林场整体基础设施环境一般,场部相对较好,管护站点则较差。同时,在领导班子建设方面应注重自主、公平,仍需提高领导水平。     

Land outsourcing and labour contracting: Labour management in China's capitalist farms

Difficulty in labour supervision has been considered to be one of the obstacles to the development of capitalist agriculture. This paper presents two distinctive labour management strategies in China's large‐scale agriculture, which contribute to the development of agrarian capitalism in China. As shown in these cases, agribusiness companies engaged in grain crop production retreat from direct labour management by outsourcing crop cultivation, while acquiring profits from upstream and downstream activities. On the other hand, capitalist producers, who are involved in the labour‐intensive and capital‐intensive crop production, tend to mobilize local elites to manage the farmworkers. Although independent labour contracting services have not emerged, a specialized group of labour contractors is being cultivated. Rural social resources are utilized in labour recruitment and supervision to minimize the labour management costs in both strategies. However, the conflicts between capital and labour are covered or replaced instead of being settled.     

国有林场贫困测定与差异性研究

基于2008—2017年国家林业局对中国28个省(市、区)国有林场的调研数据,运用等价性检验的方法从地理位置、经济状况、可持续经营和发展能力层面上对国有林场的贫困测度和差异性进行实证分析。研究结果表明:国有贫困林场不一定位于贫困县,并且与国有非贫困林场之间的差异逐渐缩小;国有贫困林场区域异质性强,经济发展水平较低;国有贫困林场在森林资源基础、人力资源基础、基础设施和生产条件等方面的可持续发展能力较差。因此,提出了相关林业部门应该鼓励国有贫困林场发展特色林产品;加大扶贫资金投入;改善职工生计条件;加强资金管理意识等政策建议。     

Are Social Costs the Outcome of Struggles over Truth?

Abstract:

This article critically examines the institutional economics theory of social costs by way of reviewing The Dark Places of Business Enterprise: Reinstating Social Costs in Institutional-Economics (2019). In particular, the article assesses the proposal to re-root institutional economics in the theoretical synthesis of “Veblen-Kapp-Mirowski” to better understand the social costs of neoliberalism. One of the findings is that while such a synthesis seems justified on the grounds of significant commonalities and the merits of deeper insights, it nevertheless runs into difficulties due to divergent philosophical foundations. One of the conclusions is that further philosophic clarification is needed on how an alternative economy would understand the relationship between “social costs” and Truth.

Feed use intensification and technical efficiency of dairy farms in New Zealand

In recent years, the traditionally pasture‐based dairy farms in New Zealand have become more intensive by using higher proportions of supplementary feed. This trend has been attributed to a range of factors, such as productivity enhancement, overcoming pasture deficits and the improvement of body condition scores. However, there is a lack of knowledge as to how feed use intensification affects the technical efficiency of dairy farms in New Zealand. This paper addresses the research gap by estimating the impact of feed use intensification on the technical efficiency of New Zealand dairy farms, using a fixed effects stochastic production frontier model and a balanced panel of 257 farms from 2010 to 2013. The empirical results show that technical efficiency on New Zealand dairy farms is positively and significantly influenced by feed use intensification, herd size and milking frequency.     

Public acceptance of and heterogeneity in behavioral beach trip responses to offshore wind farm development in Catalonia (Spain)

A combined travel cost – contingent behaviour survey of residents and tourists in Catalonia is conducted on-site to examine the effects on beach recreational demand of developing an offshore wind farm (OWF) project. The survey considers four potential OWF scenarios with different degrees of visual impact. We allow for heterogeneity in trip preferences among individuals and control for on-site sampling through the use of a random parameters negative binomial (RPNB) model and a Multivariate Poisson log-normal (MPLN) model, respectively. The welfare measures derived from the RPNB model relate to the current beach users only, whereas those from the MPLN model refer to the general population of residents and tourists in Catalonia. The results show the importance of the specific place of location of the OWF project and how the installation of wind turbines would significantly decrease the demand for trips, depending on their degree of visual impacts, leading to a substantial welfare loss. However, the results also show that the project mainly would cause a displacement of trips to other beaches within Catalonia rather than outside Catalonia and that the welfare per trip measures generated by the RPNB and MPLN models substantially differ. Policy implications of these findings are discussed.     

家庭农场经营效率及其差异分析*——基于山东234个示范家庭农场的调查

[目的]文章通过对山东省家庭农场经营效率的实证分析,旨在厘清技术、规模对农场经营效率的促进作用,通过比较分析找出各类型家庭农场短板,针对性地提出政策建议。[方法]以山东234个家庭农场数据为例,运用DEA模型对家庭农场全样本及纯种植、种养结合、种植兼休闲、种养兼休闲4类家庭农场的经营效率进行了测算和分解。[结果]首先,家庭农场综合技术效率仅为0. 170,纯技术效率和规模效率分别为0. 235和0. 786,规模效率相对充分纯技术效率不足是经营效率较低的主要原因;其次,种养结合类农场发展势头较好,纯种植类家庭农场发展滞后且综合技术效率和纯技术效率最低,种养兼休闲类农场的规模效率最低。[结论] 4类农场差异明显,应降低生产技术使用门槛,引导农场主参加职业教育,提升纯种植类农场纯技术效率,同时出台相关政策,实现土地流转的降费提效,改善种养兼休闲类农场规模效率。     

Firm adoption of international standards: evidence from the Ethiopian floriculture sector

Global trade in agriculture and food products is increasingly governed by an array of standards. In order to continue exporting, developing countries have little choice but to comply with the new requirements. This study uses a census based panel data set from the nascent floriculture industry in Ethiopia to empirically examine the determinants of firms’ adoption of international private standards in fresh horticulture produce in large‐scale estate farms. The econometric analysis shows that larger size, older, and foreign owned firms are more likely to adopt the private standards. Moreover, this study analyzes the overall industry level efforts and public–private partnership to launch and implement a national scheme GAP and build a firm's capacity to comply with the standards.
