农机服务规模经营对粮食生产效率的影响机理研究

依据2009—2019年全国31个省（自治区、直辖市）的省级面板数据,运用随机前沿分析方法和Tobit模型,考量农机服务规模经营对粮食生产效率的影响及其作用机理。结果显示：2009—2019年,中国粮食生产效率总体递增,但区域间发展不平衡;农机服务规模经营通过技术引入效应和劳动力替代效应提高粮食生产效率,其中,技术引入效应的发挥受限于农业研发支出水平及其增速,劳动力替代效应在农业劳动力成本高的区域发挥的影响效用更佳。鉴于此,应加快农业科技创新,发展粮食生产全程机械化服务,完善农机社会化服务体系。     

积极发展我国对外服务贸易——基于规避货物贸易争端的视角

加入WTO五年来,我国经济持续快速增长,很大程度得益于我国对外贸易的强劲增长.2005年我国货物进出口总额达到14221亿美元而使中国成为世界第三贸易大国,但贸易摩擦也急剧上升.随着中国经济结构的转换,有效规避不断升级的货物贸易争端,积极发展对外服务贸易必将作为我国未来对外贸易的突破口和主力军.     

以治理理论重塑我国公共服务市场化的进路

以治理理论重塑我国的公共服务市场化，其实质在于培育多元化、多渠道的公共服务主体。从而对服务的“生产职能”与“安排职能”实现相对分离。首先，鉴于公共服务领域存在着严重的“政府失灵”。应该打破政府垄断公共服务的格局，明确政府只是服务的提供者，并非一定是生产者的角色，在市场化进程中应慎用政府机制；其次。市场机制可以促进服务质量的提高、服务成本的降低、提高服务效率。充分发挥市场作用。然而。政府机制和市场机制都存在着固有的缺陷。公民社会在分担服务职能等方面也起到了十分重要的作用。培育公民社会也是市场化不可缺少的环节。

Outsourcing, Imports and Labour Demand

This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.

非审计服务、盈余管理与审计质量——来自中国证券市场的经验证据

本文以2001～2004年A股上市公司为研究对象,在国内首次验证了会计师事务所向审计客户同时提供审计与非审计服务,是否会允许管理当局有较大的盈余操纵空间,以探讨非审计服务的提供是否会影响注册会计师独立审计的质量。实证研究结果显示:在我国,控制了其他影响因素后,非审计服务的提供与异常应计数正相关,但不具有统计显著性。这表明,在我国,没有证据显示,非审计服务会的提供会损害注册会计师审计独立性及审计质量。     

In search of marginal environmental valuations — ecosystem services in Finnish forest accounting

There is currently substantial interest in valuing various services provided by different ecosystems. Concurrently economists have ascribed substantial effort on expanding traditional forest accounting systems by environmental services. This paper contributes to curtailing the existing gap between green accounting theory and applications for valuing forest ecosystem services. The multitude of links between forest ecosystem services and economy are characterized by the theoretical model for forest-economy interactions. By utilizing recently updated data we also incorporate empirical value estimates of these services comparable to other goods into Finnish forest accounting system. Finally, we discuss some problems encountered and clarify the interpretation of some value estimates incorporated to national forest account.

Feminist Ecological Economics and Sustainability

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.
