Public choice on coordinated development of border regions and its empirical research:a case study of Wuling mountain area

Due to the difficult segmentation of land destiny, popularity destiny, industry destiny on the platform of common interests demand, the regional governance of production and living for the needs of the people in cross-regional areas, such as in the aspects of security, education, assignment and management of water resources, transportation, energy, environment protection and public health, the administrative border regional cooperation is relatively easy. These aspects are equivalent to public products. Just because of this, it leads to problems that nobody will not control. The governments, in order to realize regional economic coordinated development and to eliminate the regional interests parties of administrative regions economy in microcosmic, were adapting various self-protection measures, even including that "you may have your policy but I have my countermeasures" that is derived from inter-regional economic relations. The action of market segmentation has limited the flow of various economic development elements, especially the condition of "dead end highway", resource exploitation and use, difficult social security work in social living of the administrative boundary zone. This paper studies the typical economical district of Wuling mountain area in the obvious strategic position at the junction of Chongqing, Guizhou, Hunan, Hubei provinces from the angle of regional public management and public choice to present issue awareness and academic purpose.

The Spatio-temporal Evolution and Influencing Factors ofCommon Prosperity Level in the Wuling Mountain Area

As China successfully won the tough battle against poverty,advancing common prosperity on all frontshas gradually become an important task in realizing Chinese modernization.The evaluation index system forcommon prosperity is constructed of four dimensions of“affluence,sharing,commonality,and sustainability”,andthe Entropy weight-TOPSIS method,Theil index,and Multiscale geographically weighted regression are applied toanalyzing the spatio-temporal evolution and influencing factors of common prosperity level in the Wuling Mountainarea.The results show that the level of common prosperity in the Wuling Mountain area was low but slowly increased from 2011 to 2021.The spatial development pattern of common prosperity in the Wuling Mountain areashows an evolutionary trend of being“fast in the north and east,and slow in the south and west".The core countieshave a positive spillover effect on the neighboring counties.The overall gap in the level of common prosperity in theWuling Mountain area displays a trend of“weakly fluctuating and slightly declining”,with the main source of development differences within the Hunan region.Each factor shows various impact intensit on the level of commonprosperity in the Wuling Mountain area and its fluctuation directions at different times.Among these factors,GDPper capita has the strongest impact and always plays a positive role.The conclusions of this study can provide atheoretical basis and scientific reference for the less developed regions to effectively articulate rural revitalizationand realize common prosperity.

Composition Analysis of Grape Wine from Different Brewing Technology and Its Nutrition Constituent

[Objective] The aim was to to enhance the technology to brew better the traditional grape wine, which provided theoretical basis for the development of Wuling Mountain grape wine. [Method] Taking grapes in Wuling Mountain as the row materials, Saccharomyces cerevisiae of different wines was chosen and brewed. The quality of grape wine was studied and the sensory evaluation was analyzed by dint of GC-MS. [Result] Result illustrated that the ethanol concentration of the wine brewed by exploration craft A was 68.5 g/L and that brewed by exploration craft B was 59.5 g/L; the higher alcohol content of craft A was 37.86% while that of craft B is 35.99%; craft A's percentage content of esters was 28.82% while that of B was 27.10%; craft A's percentage content of acids was 2.20% while that of B was 1.24%; the gamma-aminobutyric acid content of craft A was 33.2 g/100 ml while that of craft B was 35.4 g/100 ml. the essential amino-acid content of craft A was 11.8 g/100 ml while that of craft B was 13.9 g/100 ml .The result indicates that the wine brewed by craft A was aromatic and had special flavor. [Conclusion] In this case, the grape wine has particular flavor and has good property, which can be exploited.
