基于耗散结构的高技术虚拟产业集群准入退出机制研究

高技术虚拟产业集群是网络经济时代下的新型组织模式,其准入退出机制通过约束成员的进入与退出来有效保障集群内环境。在分析高技术虚拟产业集群具备形成耗散结构条件的基础上,建立了高技术虚拟产业集群形成耗散结构的演化模型,设计了基于耗散结构的高技术虚拟产业集群准入退出机制,从而推动集群不断地从一个耗散结构跃升到新的耗散结构,促使集群稳步有序地成长。

Dynamics of youth access to agricultural land under the customary tenure regime in the Techiman traditional area of Ghana

This paper investigated youth access to agricultural land under customary land tenure in Ghana. Using Techiman Traditional Area as a case study, the study applied multiple sampling techniques in a multi-stage sampling process to select the study communities and respondents. A total sample of 455 youth respondents and 23 elders were covered in twenty peri-urban and rural communities. The study revealed that irrespective of whichever mode (market or non-market) the youth employed to access agricultural land, in rural or peri-urban areas, there were constraints to their land sizes. Majority of the youth, both indigenes and migrants, held small land sizes of 1–3 acres for farming purposes. The underlying causes were two-fold: demand-related such as high cost of accessing land and competition from residential developers and supply-related such as unwillingness of the elders to release land and increasing scarcity of productive family land, among others. It is thus the conclusion of the paper that more research should be conducted across the country into youth access to agricultural land under customary tenure as a means of formulating an evidence-based youth agricultural land access policy for the country. There is also the need for public education of customary authorities to sensitize them on the need for making land accessible to the youth for agricultural purpose.     

Financing Small and Medium Enterprises (SMEs) in Ghana

Abstract

Issues of finance and small and medium-sized enterprises (SMEs) in developing countries have dominated the research agenda at various policy levels. However, very little empirical analysis, that is, hypothesis testing has been carried out to ascertain the relationship between finance and enterprise performance. Although a few studies have attempted to examine this relationship, yet there remain large gaps in our knowledge concerning the relationship between finance and SME development. This paper attempts to fill this gap by providing information on the relationship between finance and enterprise growth in Ghana.
