基于“中国健康与养老追踪调查”(CHARLS)数据,运用双边随机边界模型,测度了信息不对称条件下我国中老年人群的医疗议价能力。主要结论有:医生和中老年患者的议价能力对医疗价格的形成具有重要影响,医生议价能力对医疗价格的影响程度高达72.28%,而中老年患者议价能力的影响仅占27.72%;医生与中老年患者的议价能力差别,使实际医疗服务价格比基准价格高出10.94个百分点;中老年患者的议价能力随着年龄的增加呈现出明显下降趋势,而且,在实际医疗价格的不同分位数上,医患双方的议价能力也有所不同。
Based on the data of “China Health and Elderly Tracing Survey” (CHARLS), we use the bilateral random boundary model to measure the medical bargaining power of the middle-aged and elderly population under the condition of information asymmetry. The main conclusions are as follows: the bargaining power of doctors and middle-aged and elderly patients have an important impact on the formation of medical prices, the bargaining power of doctors has a high impact on medical prices as high as 72.28%, while the bargaining power of middle-aged and elderly patients accounts for only 27.72% The bargaining power of elderly patients makes the actual medical service price 10.94 percentage points higher than the benchmark price. The bargaining power of middle-aged and elderly patients shows a significant downward trend with age, and in different quantiles of the actual medical price The bargaining power of both doctors and patients is also different.
