1、原文:The Choice of Cost Drivers in Activity-Based Costing: Application at a Chinese Oil Well Cementing CompanyIn recent years, activity-based costing (ABC) has become a popular cost and operations management technique to improve the accuracy of product or service costs for firms to stay competitive. T

2、wo authors went to Xian area to collect a sample data on fuel overhead cost, number of wells, well-depth, distance, weight, and ton-kilometers at a Chinese oil well cementing company. We also verified the data accuracy with the company controller. This study investigates how to choose the appropriat

3、e cost driver of fuel overhead costs when adopting ABC . Using the linear regression analysis and the maximum r-square improvement (MAXR) model selection method, the empirical results show that among the five possible cost drivers of the number of wells, the distance from the office to the field, th

4、e weight of the cement and additive materials, the depth of well cementing, and the ton-kilometers measured by the product of the distance and the weight, the best cost driver is the product of the distance and the weight. Thus, by applying the ABC system and using the product of the distance and th
