Core Viewpoint - The article emphasizes the necessity of in-depth field research to obtain accurate and comprehensive insights into industry conditions, as relying solely on public data is insufficient in a rapidly changing global market [1]. Group 1: Methodology Core Concepts - The field research methodology of QYResearch is based on two core concepts: vertical penetration and horizontal validation [3]. - Vertical penetration involves comprehensive research along the value chain, from upstream suppliers to downstream end-users, to capture subtle changes in cost structures, technological barriers, and supply-demand relationships [3]. - Horizontal validation entails comparing and verifying information across similar companies in different regional markets or segments to enhance the robustness of market size, share, and growth rate predictions [4]. Group 2: Key Steps in Field Research - QYResearch's field research process is systematized into four interconnected stages, starting with in-depth corporate interviews and factory visits to gather critical insights from key functional leaders [5]. - The second step involves market channel and end-user visits to understand how products reach final users, which is crucial for predicting market prospects [5]. - The third step includes data cross-validation and insight extraction, where information obtained is systematically verified and integrated to identify anomalies and enhance predictive accuracy [7][8]. Group 3: Unique Value of Field Research - The rigorous methodology allows QYResearch to provide unique value in its reports, combining solid field insights with robust data models to support clients' strategic decision-making [9]. - The research offers real cost structure analysis, uncovering raw material, labor, and manufacturing costs to forecast industry profit trends [10]. - It also reveals unpublished technological developments and provides a precise view of capacity layouts, identifying actual production rhythms and scales [10].
