作者： hu senlin

After last year CNOOC＇s bidding for buy the US energy company Unocal Corp lost out to the Chevron Corporation, it conducted the crossing-border asset-acquirement again in the beginning of this year. On Jan. 9, 2006,CNOOC Ltd signed a definitive agreement with Nigeria South Atlantic Petroleum Limited （SAPETRO） to acquire a 45 % working interest in an offshore oil developing license OML 130 in Nigeria for US$2.268 billion cash. The purchase will be funded by the internal capital resources of CNOOC Ltd. In which, US$1.75 billion will pay for buying SAPETRO, and the remaining cash will be used to pay for the early operation cost.

在经历百年未有之大变局的当下,我国区域发展总体格局演变的态势如何?哪些地域担当了区域增长极角色?推动区域发展的核心动力是什么?这些都是经济地理学者关心的问题。文章从科技创新、产业结构、经济发展三个方面入手,借助地理联系率、双变量Moran指数等分析工具,刻画2006—2019年中国区域发展格局的演变过程,分析内部作用机理,导出政策启示。研究发现:(1)2006—2019年,中国东西部发展差异呈现逐渐缩小态势,但南北发展差异却逐渐增大,我国东西"单向"发展不平衡的总体格局呈现出向东西、南北"双向"发展不平衡的方向演变。(2)城市群和中心城市对我国区域发展的支撑作用巨大,我国城乡"单向"发展不平衡格局向城乡、大城市与中小城市"双向"发展不平衡的方向转变。2006—2019年,19大城市群汇集了全国88%的GDP、93%的专利。(3)经济发展质量越来越高。"创新驱动、转型发展"政策效益呈现显现。2006年以来,科技创新、先进制造、经济发展三者空间关联关系不断增强。此外,针对中国区域发展现实问题,提出了加大支持东北地区、边缘地区中小城市创新能力建设、高质量发展,扶持"双向飞地"建设等对策建议。

山东的无棣大山和栖霞方山是两个以霞石岩为主的新生代火山,含有大量的地幔橄榄岩捕掳体,橄榄岩捕掳体中的尖晶石常见黑色反应边。在BSE图像上,这些反应边根据结构的不同又可以进一步分为两种:筛状边和均一边。有时两种反应边在同一颗尖晶石中共存并相互过渡。尖晶石捕掳晶和捕掳体中与寄主岩直接接触的尖晶石常发育均一边;发育筛状边的尖晶石则一般不直接与寄主岩接触,但位于捕掳体的边缘。尖晶石的筛状边呈多孔状,为富Cr尖晶石或铬铁矿。筛状边成分上与核部(Cr_2O_3=7.52%~36.75%,Cr#=7.80~44.20,Mg#=44.70~74.48)区别明显,具有高的Cr_2O_3含量(23.42%~65.96%)、Cr#值(78.97~92.49)以及低的Mg#值(17.22~43.02)。另外,筛状边相对其核部(TiO 2=0.00%~0.53%,MnO=0.04%~0.35%)还显示偏高的TiO 2(0.20%~3.60%)和MnO(0.29%~1.93%)。在筛状边附近存在富Al_2O_3(8.00%~17.57%)和MgO(17.89%~26.02%)的玻璃。尖晶石的均一边无孔洞但多发育裂理,成分上与核部突变,并以富TiO 2(20.90%~6.64%)和FeO T(70.79%~53.92%)为特征,最外部为钛磁铁矿。均一边具有明显的成分分带,表现为由内至外TiO 2、FeO T含量逐渐增高,Al_2O_3(0.04%~16.34%)、Cr_2O_3(0.77%~25.69%)和MgO(0.50%~7.16%)含量逐渐降低。尖晶石的两种反应边与寄主岩密切的空间关系说明其成因与寄主岩浆有关。虽然尖晶石筛状边的Cr#值(79.0~92.5)明显高于核部(7.8~44.2),但是其相对核部偏高的TiO 2和MnO含量,以及显著降低的Mg#值均与单纯的部分熔融趋势不吻合。根据尖晶石两种反应边的结构特征、成分特征和相互的空间关系,我们认为筛状边与均一边是岩浆与尖晶石反应不同阶段的产物。当橄榄岩捕掳体被岩浆捕获后,由于成分上的不均衡两者之间将发生溶解反应。反应过程中,尖晶石中不同元素向熔体迁移的速率区别明显,其中Cr是最难熔的元素也是迁移最慢的元素。在反应的初始阶段,由于易溶组份Al、Mg等元素随熔体迁出,尖晶石发育筛状边,并同时伴随Cr#值的显著升高和Mg#值的显著降低。此时,寄主岩浆中的Ti、Mn等元素也部分扩散进入筛状边中的残留尖晶石。如果熔体足够多,反应得以持续进行,筛状边中的Cr最终也将被熔体带走。在反应产生的混合熔体中金属氧化物最早达到饱和并结晶。随着反应的持续进行,结晶出的矿物将继续生长、变粗,并相互连接,直至孔洞消失形成均一边。同时伴随着矿物的不断结晶,溶解界面上的熔体成分也不断变化,从而使均一边具有明显的成分分带。在橄榄岩捕掳体内部,由于渗进捕掳体中的岩浆有限,渗透岩浆与尖晶石之间的反应多限于早期阶段,反应产物为筛状边。在捕掳体边缘,与寄主岩浆直接接触的尖晶石由于参与反应的岩浆量足够多,因此一般产生反应的终端产物———均一边。

创新是推动黄河流域高质量发展的重要途径之一。利用2006—2018年黄河流域79个地级以上城市的面板数据,首先构建指标体系对各城市技术创新及绿色发展水平进行分析,其次通过面板计量模型深入探究技术创新对城市绿色发展的作用机理。研究表明:①2006—2018年,黄河流域城市技术创新与绿色发展水平均得到明显提升,但空间差异显著,总体呈“下游>中游>上游”阶梯式递减特征。②黄河流域城市技术创新对绿色发展总体上没有显著影响,但在加入技术创新的二次项后,两者之间呈现显著的“U”型非线性关系,即技术创新先抑制后促进城市绿色发展,这也验证了技术的“回弹效应”假说;③技术创新对黄河流域城市绿色发展的影响可以通过直接效应和间接效应共同体现,但这两种效应正好相反,即一个城市技术创新能力的提升对该城市绿色发展存在显著的“U”型(先抑制后促进)关系,但对邻近城市的作用呈现倒“U”型相反的关系。根据研究结论,从技术创新对城市绿色发展的直接效应和间接效应2个方面提出了相应的政策建议。
