Multi - element production capacity , closely related to corporate earnings , is a key indicator to determine the input - output ratio of economic activities 摘要多要素生產率是衡量經濟活動過程中投入產出效率的一個重要指標,與企業的盈利能力密切相關。
The principal factors affecting the stimulating effects of the field tests are shown . 341 above tests have been made with additional output of 28375t and input - output ratio of 1 : 2 微生物吞吐、微生物清防蠟、微生物堵水調剖和激活本源菌共進行341井次,增加原油產量28375t ,投入產出比均大于1 : 2 。
So that , one consideration on the optimal scales of industrial clusters comes out , that is , is there a best scale in which the total benefits , input - output ratio , is maximum or not 這樣就引發了對產業集群演化發展過程中合理規模的思考:是否存在一個最佳的規模(資產總量) ,使得集群整體的效益最大,即資金產出率(總產值/總資產)達到最大
( 2 ) the maximum of input - output ratio is strikingly promoted by the level of technical developing and unrestraint of resourses . and at the same time , it ’ s positively and distinctly influenced by the factors of natural resourses amount , techological support , govenment policies , labor supply , public foundation , intermediary service , maket overlay ( from high influence to low ) ( 2 )集群的資金產出率的峰值(最大值)受到集群的自然資源非限制性、技術發展水平的影響顯著;同時也受到外部環境因素的明顯影響,由影響程度從高到低排序如下:自然資源、技術支撐、政府政策、勞動力供給、公共基礎、中介服務、市場輻射的提供能力。
