摘　　要：运用基于似不相关回归系统和自举临界值沃德检验的新方法研究中国高技术产业五大行业创新投入和创新产出之间的格兰杰因果关系。结果表明,电子计算机及办公设备制造业明显存在从创新产出到创新投入方向的格兰杰因果关系,尤其是存在新产品开发经费和新产品销售收入之间的双向格兰杰因果关系;医药制造业明显存在从创新投入到专利申请和从新产品销售收入到新产品开发经费的单向因果关系;医疗设备及仪器仪表制造业存在从新产品开发经费到专利申请和从新产品销售收入到新产品开发经费的单向因果关系;航空航天器制造业和电子及通信设备制造业不存在任何方向的格兰杰因果关系。This paper examines the causal relationships between the logarithms of real innovation input and real innovation output in 5 industries. A new panel cau- sality analysis is used which is based on SUR systems and Wald tests with industry specific bootstrap critical values. The results indicate one-way causality from inno- vation output to innovation input in Manufacture of Computers and Office Equip- ments, one-way causality from innovation input to Patent Applications and from Sales Revenue of New Products to Expenditure on new Products Development in Manufacture of Medical Equipments and Measuring Instrument, one-way causality from Expenditure on new Products Development to Patent Applications and from Sales Revenue of New Products to Expenditure on new Products Development in Manufacture of Medicines, while in the case of the other industries there is no evi- dence of causal relationships in either direction.
