The method proceeds from natural crop yield of Ukrainian lands provided that crops rotation is observed and lands are operated only mechanically with the use of no fertilizer. Nature-resource potential of Ukraine and its Carpathian Region are assessed in the aspect of administrative oblasts. Specificities of nature-resource potential’s use by farming enterprises are characterized. Peculiarities that effected upon formation of farming in Ukraine are reviewed.

Axioms of the classical Shapley value are extended to Shapley values with fuzzy payoffs by using fuzzy sets theory. Fuzzy Shapley function is defined based on these extended axioms. From the viewpoint the allocation for each partner should be a crisp value rather a fuzzy membership function at the end of cooperation, a crisp allocation scheme based on fuzzy Shapley values is proposed.展开更多

The results show that customer concentration plays a mediating effect in the relationship between strategic deviance and enterprise value. The strategic deviance is positively correlated with customer concentration and negatively correlated with enterprise value. The management of agricultural enterprises must pay attention to the customer relationship problems caused by strategic deviance,reduce the risk of enterprises,and gradually enhance the value of enterprises.展开更多

There were three innovation points as follows: first of all,two key demands of apparel companies to existing brand value were summarized through investigation; then,the concept of rapid brand value evaluation and multi-dimensional factors( MDFs) was presented; finally,the relationship between apparel corporate brand value and the sales revenue in apparel market with the sales revenue was proven by empirical research.During the process of empirical study,the sales revenue data of 66 apparel enterprises domestic and abroad were collected,and the regression analysis has been done on the relationship between the corporate brand value and the apparel market sales revenue of apparel enterprise. The empirical research showed that they were positively correlated to each other. This conclusion presented a method of judging brand value development trend quickly by single indicator.展开更多

However, the adaption of RE-technologies for Swiss enterprises relies on tangible financial returns, based on complex calculations. This article analyses business opportunities(BOs) of eight Swiss SMEs considering the net present value of RE-investments in an uncertain economic environment. We identify two profitable BOs for Swiss SMEs and three which are not profitable. Further, the article demonstrates that the profitability of such investments remains mostly positive even under economic uncertainties. Surprisingly the profitability does not change significantly if the SME receives a subsidy or not. The support instrument of the Swiss Government has not a ponderous impact on the decision to invest in RE-technologies or not. Therefore, the article emphasizes the importance of including SME in the Swiss attempt to decentralize the energy market.展开更多

文摘Fuzzy Shapley values are developed based on classical Shapley values and used to allocate profit among partners in virtual enterprises (VE). Axioms of the classical Shapley value are extended to Shapley values with fuzzy payoffs by using fuzzy sets theory. Fuzzy Shapley function is defined based on these extended axioms. From the viewpoint the allocation for each partner should be a crisp value rather a fuzzy membership function at the end of cooperation, a crisp allocation scheme based on fuzzy Shapley values is proposed.
文摘From the perspective of strategy,this paper uses A-share agricultural listed companies( 2011-2016) as samples to study the impact of strategic deviance on enterprise value,to explore whether customer concentration plays a mediating effect. The results show that customer concentration plays a mediating effect in the relationship between strategic deviance and enterprise value. The strategic deviance is positively correlated with customer concentration and negatively correlated with enterprise value. The management of agricultural enterprises must pay attention to the customer relationship problems caused by strategic deviance,reduce the risk of enterprises,and gradually enhance the value of enterprises.
