電子化跨域治理成效指標之設計與衡量：主觀性測量指標的應用與比較

The Design and Measure of Electronic Cross-boundary Governance Performance Indicators: The Application and Comparison of Subjective Measure Methods

跨機關資訊分享成效的評估，是當代電子化跨域治理的核心議題之一，但，如何進行有效的衡量，在研究上仍有缺口。是以，本研究嘗試從研究方法中的測量角度，探討何種指標設計較能適用於跨機關資訊分享成效之評估，以作為未來公共組織評估電子化跨域治理成效之參考。本研究經由次級資料分析，以「全國商工服務行政系統」和「國稅資訊系統」之內部系統使用者的觀點進行探討。一方面，評估不同主觀性指標測量結果的相似性，即比較「態度性」和「事實性」評價指標之個別題項的衡量結果在內容效度、建構效度及信度等結果的異同；另一方面，分析不同主觀性指標測量結果與效標的關聯性，即檢視「態度性」和「事實性」評價指標之整體構面衡量結果與外部變項的效標關聯效度，這是過去研究鮮少著墨的部分。在現有的資料條件下，本研究發現，在指標相似性部分，態度性評價指標題項的內容效度、建構效度及信度相對良好與穩定，而事實性評價指標的結果則是優劣參半；在指標關聯性的部分，態度性評價指標的效標關聯效度同樣較佳，較能反映出與關鍵變項之間的關係及強度，事實性評價指標的結果就顯得差強人意。就此而論，未來在評估跨機關資料分享成效時，本研究建議以態度性評價指標為優先考量，事實性評價指標次之。

While evaluating the performance of information sharing between public organizations is a critical issue in electronic cross-boundary governance, there is still a research gap in the development of measurement instruments. It is our objective to develop several performance indicators and compare their results through two representative cases (i.e., the Commerce Industrial Service Portal and the eTax Portal ). We conducted a secondary data research using the data collected from the perspectives of internal system users. On the one hand, this research focused on the similarity of two kinds of subjective performance indicators (i.e., attitudinal measures indicator and factual measures indicator) in terms of the indicators’ variances within each item on the results of content validity, construct validity and reliability. On the other hand, this research examined the relationships between the subjective performance indicators and other variables in terms of their criterion-related validity, an area of study which is seldom mentioned in the current literature. Based on the existing data, we found that attitudinal measure indicators are more delicate and stable than factual measure indicators for most of the estimations. Accordingly, we suggest that further study should give priority to attitudinal measure indicators for evaluating the performance of information sharing between different organizations.
