A foreign firm has a patent on a technological innovation that reduces the costs of all firms. The foreign firm can license the innovation to one or both domestic firms. The authors consider two standard licensing policies： （1） auction policy and （2） unit royalty policy. The foreign firm can license the innovation either by staying outside the domestic market, or it can enter the market, license the innovation and compete with the domestic firms. The authors show that （1） when the foreign firm stays outside, it is never optimal for it to use royalties, （2） if it licenses the innovation by entering the industry, then royalties could be optimal and （3） when it decides on its entry strategy by taking its optimal licensing policies into account, it always finds it optimal to enter the domestic market.展开更多

It is the basis of the study on the quan-titative remote sensing. In this paper, the radiative characteristics of soil, vegetation, and atmosphere were described respectively. The numerical solution of radiative transfer was accomplished by Successive Orders of Scattering (SOS). A radiative transfer model for simulating microwave brightness temperature over land surfaces was constructed, de-signed, and implemented. Analyzing the database generated from soil-vegetation-atmosphere radiative transfer model under Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) configuration showed that the atmospheric effects on microwave brightness temperature should not be neglected, particularly for higher frequency, and can be parameterized. At the same time, the relationship between the emissivities of the different channels was developed. The study results will promote the development of algorithm to retrieve geophysical parameters from mi-crowave remotely sensed data.展开更多
