As to the first research topic, we present a 'Noble Brand Positioning Four Master Phases Theory': Brand Space Theory, Brand Capital Theory, Brand Value Theory and Brand Circle Theory in advance. Following based on the Principal Component Analysis of statistical theory, we implemented the quantitative research in the 'Noble Brand Positioning Four Master Phases Theory'. We used the most famous fast food brand 'McDonald' s' as the sample space. The simulation test result shows that the Overall Index Explanatory Power is 83% under the Cronbath' s a is 0.88 through the quantitative verification. This result gives a strong support in defining the Noble Four Niche Phases Theory as the important strategic factor in establishing brand positioning index. After completing the quantitative research, the Principal Weight of each Sub-Niche is positive. This also implies that the Noble Brand Positioning Four master Phases Theory represents positive affection to brand positioning index. We also created the following Sub-Niches those are rarely mentioned in the past literatures. The Sub-Niches are:'Endless Running Strategy, Business Environment Strategy, Physical Capital Strategy, Brand Logo, Brand Music, Business Life Strategy, Personnel Capital Strategy, Life Cycle Strategy, Trust Mask Strategy, Re-Positioning Strategy, Word-Power Strategy, Globalization Strategy, Network Revolution Strategy and Green Brand Strategy'. The quantitative verification model can classify the responses of the sampling space into groups. After that, we used the quantitative verification process to classify the Target Consumer. And through the Principal Component Analysis, the group that owns the biggest average value consists of the Master Target Consumers for the business. This result would become the best suggestion for the business to adjust its strategies and to upgrade the productivity efficiency and create higher profit. As to the second research topic, we focused on finding the best corresponding characteristics attributes of the Brand Music for the Brand Log.

Secondly, by linearizing the system at the unique positive equilibrium solution and analyzing the associated characteristic equation, it is found that the positive equilibrium solution is asymptotically stable when the delay equals to zero and when it is increased to certain critical value, the positive equilibrium solution will loss the stability and a spatially heterohomogeneous periodic solution will bifurcate from this positive equilibrium solution.

1Niche construction can lead to stable coexistence of diverse genotypes in spatially structured population, which supports a stable polymorphism even without heterozygote superiority.(2)With habitat deterioration, niche construction accelerates the formation of steady polymorphism and hence impedes the harmful influences of environment on the population, which might embody a life-history strategy of organism under the unfavorable environment.(3)Niche construction results in the coexistence with alternative polymorphism through genotype-environment feedback and limited gene flow.(4)The niche-constructing organism is an active force to alter its environment and hence the direction of natural selection in order to better survival.(5)Spatial dynamics and distribution pattern of metapopulation are profoundly influenced by time-lagged niche construction.(6)Metapopulation size can reach a fixed level in the recency effect and equal weighting of time lag but is statistical stability in primacy effect, which implies the primacy effect is most remarkable.(7)The increment in the relative weightingof each generation\' niche construction and the length of time lag are significant factors for system destabilization.(8)Moderate capacity of positive niche construction benefits the metapopulation persistence.(9)The narrowing of niche breadth can decrease the metapopulation size and thereby increase the extinction risk.(10)The coupled function of time lag and niche construction make the system oscillation and generate the spiral wave, spiral-broken and circular wave in heterogeneous habitat.The spatial distributions of metapopulation and resource content are complementary due to a phase lag of their both frequencies.(12)Metapopulation persistence with niche construction depends not only on the balance between colonization and extinction, but also on the balance between the ability of niche construction and natural dissipation of habitat.(13)Metapopula-tion can survive under certain condition when the percent of suitable patches in habitat is lower than the ration of extinction to colonization.(14)Two thresholds exist in the process of transition of habitat quality dynamics from unsuitable to suitable, which include the intensity of niche construction and the initial condition of system.(15)Metapopulation size is positive correlated with the ability of positive niche construction, which means that organism or population who has strongly positive influences on their environment plays an important role to maintain the available habitat.
