大北京：波核影响下双环-掌状网络发展模式研究

大北京城市圈的发展遵循聚集经济理论与波核理论，即在北京经济核的影响下按照影响强度逐渐降低的规则由中心向外围呈环状拓展，在这种发展模式下，大北京将呈现双环掌状网络发展趋势。由于区域内不同方向上的经济发展状态不同，大北京向外围空间的拓展呈现差异发展态势，沿石家庄-保定-北京-承德一线，东南区域是大北京的主发展区域，西北区域是次发展区域。在掌状发展模式下有选择地刺激大北京腹地内次一级的经济核的发展，会改善北京与周边的次级城市之间的联系，并实现大北京腹地经济的协同发展。

Big Beijing Rim:Double- ring- palm Network Development Mode under Impact of Wave- core

The development of Big Beijing Rim conforms to conglomeration theory and wave-core theory.In other words,Big Beijing Rim expands outward from its economic center with the influential intensity reducing from the core area to the peripheral area.Under such trend,Big Beijing Rim is to develop in double-ring-palm mode.As different directions in this region tend to develop to various extents,expansion of Big Beijing Rim toward peripheral area exhibits asymmetrical trend in terms of development.The whole region can be divided by the line of Shijiazhuang-Baoding-Beijing-Chengde,defining southeast area to this line as main developing area,and northwest to this line as subordinate developing area.Under DRP mode,to strengthen the development subordinate core can enhance the relationship between Beijing and its peripheral second-tier cities and realize the consistently economic development of Big Beijing Rim.
