This paper analyzes two competing explanations for the ownership of ancillary facilities by referring physicians: indirect demand inducement and quality assurance. Consistent with the demand-inducement explanation we find physician-owned clinics treat patients for 50 percent more visits than do independent clinics and the differential is directly related to factors facilitating demand inducement. We find no difference in quality of care across ownership structures, however. In further support of the demand-inducement hypothesis we find that physical therapists are less likely to work in physician-owned clinics in states where therapists are allowed to practice independently.
间接需求诱导和质量保证。与需求诱导的解释一致，我们发现医生拥有的诊所治疗的患者就诊次数比独立诊所多50%，且这种差异与促进需求诱导的因素直接相关。然而，我们发现不同所有制结构的医疗质量并无差异。为进一步支持需求诱导假说，我们发现，在允许物理治疗师独立执业的州，他们在医生拥有的诊所工作的可能性较小。
