Abstract The nations & regions GDP (gross domestic product) will represent their comprehensive strength in views of economy level and quality, so searching it may have an important effectiveness for us to process statistic with the national producing amount every month, season and year. In the meantime, the value with y-y has also a significant meaning that reflects the economy growth step because we should clarify the increasing change so as to evaluate the increasement and declination value preciously. The positive y-y value may mean the good and rapid economy developing status whilst the minus one may state the bad and slow economy step. So we judge the economy developing enhancement and decreasement through that y-y value for a certain period. Meantime, the toughness of national economy developing force will be shown by the y-y value because some regions remained a low economy situation but its y-y value had high one explained the high toughness with such regions besides the low GDP value. So that the new-quality productivity will be sought by us continuously special by those scientist, senior engineer, experts because they can lead to new feasible energy and dynamic force to drive the new one into realizing new-quality productivity producing a certain effectiveness to GDP enhancement as last. In the meantime, the new-high-technology product will be formed accordingly that can create the industrial chains to support the high-knowledge skill transformed into the more comprehensive and complicated product for the sake of serving our citizen with modernization. The emerging technology would be driven the new energy force that includes the low -carbon and low-contamination electricity generator which may form the new quality productivity protected our earth from carbon-oxide and nitric-oxide etc. release. So that some the high-tech products would aware that the transformation and positively prepare the futural product producing and application. Thereby, the nations GDP will reflect the whole economy special in new high-tech-field maker and products will play a significant influence on that value increasement and control the y-y value under our consideration.
