各個生物族群數(shù)量的計數(shù)、地理區(qū)域的分佈狀況。 ? 生態(tài)研究的第一步工作。 分佈構面的子構面 ? 族群的強度 ? 族群強度在衡量不同族群之間的相對強度 , 藉以分析族群間的強弱關係並可定義它們之間的行為關係 。 一般而言 , 族群的強度可以利用族群的種類 、 族群內生物體的個數(shù) 、 分佈區(qū)域 、 及在食物鏈上的關係等構面來衡量 , 可用來描繪群落內族群的分佈輪廓 。 ? 物種的多樣性 ? 衡量群落內物種的豐富程度,生態(tài)系統(tǒng)的一個重要觀察 指標。 ? 多樣性與穩(wěn)定性關係法則( Diversitystability principle) A Knowledge Ecology ? Basic species in a knowledge ecology is different types of knowledge that belong to the anization. ? The goal of KM is to build a mechanism by which a healthy balance of knowledge can be maintained for achieving superior performance. Diversity vs. Stability ? In ecological rules, the diversitystability relationship is a major principal, which says an ecology is more stable if it maintains a certain level of diversity. ? Similarly, we would like to examine whether the same rule holds in a knowledge ecology, ie, anizations with more diversified knowledge are more stable in performance.

H1: Relationship Between IT and Knowledge Ecology ? H11: Higher IT capabilities support higher knowledge ecology ? H12: Higher IT capabilities support higher knowledge diversity Hypotheses (2) ? Relationship between Knowledge diversity and firm performance ? H21: Higher knowledge intensity results in higher average performance ? H22: Higher knowledge intensity results in lower performance variations Hypotheses (3) ? Relationship between knowledge diversity and firm performance ? Higher knowledge diversity results in lower average performance ? Higher knowledge diversity results in lower performance variations Criteria for Choosing Industries ? Four industries were chosen based on their knowledge intensity and environmental uncertainty. ? Knowledge intensity is measured as the ratio of product price by the tangible costs (including material costs and depreciation of fixed asse
