Study on the comprehensive advantage evaluation method of high-tech enterprises based on RBF artificial neural network

This paper designs an intelligent evaluation approach using a Radial Basis Function （RBF） Artificial Neural Network. We based our approach on establishing a comprehensive advantage evaluating index system that offers scientific substance for creating a development plan and the strategic management of high-tech industry and regional clusters of high-tech enterprises. Furnhermore, this paper selects some typical high-tech enterprises＇ data to make comprehensive training on the network system. Meanwhile, the paper chooses some enterprises as testing samples to test the method, the result of which proves that this method is truly effective. The research of this paper provides a comprehensive advantage evaluating and managing method for high-tech enterprise.

Comparative Advantage of Maize Production in Jilin Province

The comparative advantage of maize production in Jilin Province was analyzed based on the sow area index,unit yield index,benefit index and comprehensive comparative advantage index in this study.The results showed that compared with other provinces in China,there was obvious comparative advantage in sow area index and unit yield index of maize in Jilin,the average of which stood for the first and the fourth in China from 2002 to 2006;there was no comparative advantage of benefit index compared with the average value of the whole countries,the average of which stood for the 14th in China from 2002 to 2006;the comprehensive comparative advantage in Jilin provincial maize production showed significant comparative advantage,the average of which stood for the fourth in China from 2002 to 2006.On the basis of the above,the suggestions to develop maize production in Jilin province had been put forward.

Human Capital Comparative Advantage n Large Developing Countries

With human capital levels.Jar lower when compared to developed countries, large developing countries derive their comparative advantages from the coupling between heterogeneous human capital and a diverse industrial structure, physical capital investment and technological level. This theory explains that despite low levels of human capital, large developing countries can still achieve rapid economic growth. Empirical research using the coupling factor model has supported this theoretical hypothesis. The policy implications are obvious： Large developing countries should enhance the adaptation of human capital to diversify their industrial structure, physical capital investment and technological level while constantly increasing human capital investment. This approach will tap their full potential, avert their weaknesses and promote rapid and sustained economic development.

Competitiveness of the Kelp Industry Cluster in Rongcheng City,Shandong Province

In order to study the development status of kelp industry in Rongcheng in recent years, the centralization degree of kelp industry clusters and the comparative advantage of kelp industry in Rongcheng, Xiapu and Jinpu from 2010 to 2020 were compared and analyzed by indicators such as location quotient index, industrial agglomeration index, coefficient of concentration, scale advantage index, efficiency advantage index, and comprehensive advantage index, and the deep-seated factors affecting the competitiveness of kelp industry in Rongcheng were analyzed. Meanwhile, measures of improving the competitiveness of the kelp industry cluster in Rongcheng were put forward.
