Internal Drivers and the Specialization Status of Under-developed Countries: Evidence from China's High-tech Industry

This study incorporates value-added ratio （VAR） and productivity into the analytical framework of intra-product specialization （IPS） as a globally comparable index for international specialization status （ISS）, to analyze the effect of domestic technological innovation, labor force investment, capital investment and foreign direct investment （FDI） spillovers on the ISS of developing countries. It also tests the effects empirically against the data from Chinese high-tech industries and enterprises. The results show that domestic technological innovation and the improved coordination of material capital and human capital are key internal drivers in the improvement of the ISS of Chinese high-tech industries, whereas FDI spillovers play a relatively limited role therein. Therefore, the key to China＇s industry upgrading is to tap and nurture the internal motive forces rather than to rely on FDI spillovers.

Objectifying Research on Special Region Corresponding to Five Internal Organs in Colour Inspections of Chinese Medicine

Objective：To study the differences in a special region（SR） corresponding to five internal organs between the young and the elderly and to verify the effectiveness of a developed system for objectifying research in colour inspections of Chinese medicine（CICM）.Methods：An image acquisition device imitating daylight to meet the requirement of CICM was designed.Image processing software based on CICM theory was developed.A total of 83 normal people were sampled and assigned to two groups.The first group（Group I）included 30 people with an average age of 24 ±2,and the second group（Group Ⅱ） included 53 people with an average age of 74 ±4.After image processing,the chromaticity of 10 SRs corresponding to five internal organs was calculated.R,G,and B represent the chromaticity of color red,green,and blue,L indicates color brightness,whereas a and b denote red and yellow respectively.The difference between the young and the elderly was analyzed.Results：（1） The chromaticity of each SR corresponding to five organs was obtained.The average R,G,B,L,a,and b of the sample were 194.4,147.6,119.3,65.2,15.5,and 22.3,respectively.（2） The R,G,B,and L of the young were greater than those of the elderly,but the a and b of the young were less than those of the elderly.（3） A statistically significant difference in each SR was found between the young and the elderly（P0.05）.The total differences for the Lung（Fei）,Heart（Xin）,Liver（Gan）,Spleen（Pi）,and Kidney（Shen） were 50%（3/6）,66.7%（4/6）,66.7%（4/6）,83.3%（5/6）,and 91.7%（33/36）,respectively.However,the Kidney SR had the greatest statistical discrepancy.Conclusion：The old Chinese saying that human Kidney deficiency worsens with age was verified by the results.The objectifying system used to examine CICM was effective.Thus,this system may be used as a basis for further research.
