摘 要:晶片一直是中國半導體產業的痛中之痛,常常被國外半導體巨頭掐住脖子。在中國晶片被美國限制之後,中國政府開始意識到晶片是重中之重,對國產晶片的支持力度逐漸加大,大基金扶持,IC 產業園建設,各種項目孵化推進,可謂熱火朝天,湧現了一大批從事晶片設計、生產、銷售的公司。作為一個初創的晶片領域公司,市場的預測和庫存的優化成為一個關鍵的問題。創新型晶片產品具有生產週期長、生產成本高等特點,對相關市場進行精確預測可避免庫存過高造成的損失。本文提出基於遺傳演算法進行參數估計,改進 BASS 模型以分析創新型晶片市場擴散。與考慮季節因素的最小二乘法參數估計的BASS 模型相比,驗證了本文的創新模型具有更精確的預測效果。進而採用實例數據實證了本模型在晶片為重要組件的高新技術產品市場中的適應性。研究表明晶片市場在前期主要由內在創新推動消費者購買,而在擴散過程中,逐步過渡以用戶的口碑傳播為主。晶片生產和使用企業可運用該模型,根據不同階段的預測結果,進行經營策略的調整從而實現企業利潤的最大化。

Abstract: Innovative chip products have a long production cycle and high production costs.Accurate prediction of relevant markets can avoid losses caused by excessive inventory.This paper improves the BASS model with parameter estimation based on genetic algorithm to analyze the market diffusion of innovative chips.Compared to the BASS model with least squares parameter estimation considering seasonal factors,the novel model proposed in this paper has a more accurate prediction.Furthermore,the adap tability of this model in the market of high-tech product with chips as important components is demonstrated by example data.Research shows that the chip market mainly promotes consumer purchases through internal innovation in the early stage,and in the process of diffusion,the gradual transition is mainly based on word-of-mouth communication of users.Chip production and application companies can use this model to adjust their business strategies based on the prediction results at different stages to maximize corporate profits.
