摘要：The New Institutional and Transaction Costs Economics framework is incorporated to transitional Bulgarian agriculture, and level of sustainability of dominating subsistent farming, production cooperatives, small-scare commercial farms, and large agro-firms assessed. New framework for assessing sustainability of farms and for governing of sustainable development is suggested taking into account: role of specific institutional environment, comparative efficiency of various market, private, public and hybrid governing modes, transaction costs and critical factors (frequency, uncertainty, asset specificity, and appropriability) of farm transactions. Analysis of sustainability of different types of Bulgarian farms is made, and further domination of subsistence farming, cooperatives, large agrofirms, and some part of small commercial farms projected.
