论政府包办型生态建设补偿机制的低效性成因及应对策略

政府主导型生态建设的资金投入通过政府委托代理链最终到达“种树人”环节。由于链条本身存在重复性大规模剥蚀资金的缺陷,当资金到达最终环节时,往往因数量的大幅减少而陷入高成本低收益困境。即使那些能够到达最终环节的资金,也会因补偿机制的不适当而缺乏效率。如何克服这种由政府包办而形成的低效率补偿机制?基本途径是让资金运动绕开政府委托代理链,直接到达最终环节,实行治理成果与补偿机制直接挂钩的激励与约束机制。

Money as Social Exergy

Synopsis It has been proposed that open thermodynamic systems will act to dissipate available energy gradients by self-organizing into coherent structures that, with time, evolve and develop into nested hierarchies – panarchies – that adapt to internal and external changes according to a characteristic adaptive cycle. This paper seeks to apply these ideas in the purely societal realm by investigating the role of money in economic systems. Money represents the value embodied in goods; a value that is separate from the exact nature of those goods. We suggest that money thereby liberates the ‘free value’ of economic desire and that this free value has properties analogous to energy. The result is the self-organization of structures and systems (‘econosystems’) that dissipate this ‘free value’. Econosystems act at different scales, and nested levels of econosystems form a panarchy, having effects that can be observed. In particular, it appears that money facilitates the creation of relationships between econosystem actors, increasing the connectedness of the econosystems that envelop those actors. We have identified a phenomenon whereby freed social value (i.e. money) can aggregate, or pool, at a larger econosystem scale in structures such as banks. These pools act as gradients that actors at the neighborhood scale can exploit for self-organization in the econosystem. Thus, econosystem actors appear to be freed from thermodynamic constraints by using money as a means of self-organization. However, because of these pools of aggregated social exergy, connectedness is increased at the larger scale of the econosystem. The potential consequence of this dynamic is that money may act to push larger scale econosystems toward a state of heightened vulnerability to collapse, while freeing smaller scale actors from apparent constraints. In this way, we propose that money acts to skew information feedback loops between econosystem actors and larger scale structures such as economies and ecosystems.      

北部湾城市群自然资本利用状况、空间分析与驱动因素

以北部湾城市群为例用三维生态足迹模型、偏最小二乘法、空间计量模型分析了其自然资本利用状况、空间相关性、驱动因素。结论:(1)城市群自然资本利用处于不可持续状态;(2)自然资本利用程度划分为低、中、高三类,城市也相应分成三类;(3)自然资本利用的主要驱动因素是人口因素、社会经济;(4)空间分析显示全局莫兰指数为正,空间集聚显著,表明自然资本利用存在空间正相关;空间误差模型拟合度最好,并证明自然资本存量占用与人口总量正相关,与GDP总额负相关。

我国粮食市场价格波动及应对措施——基于物流成本的视角

造成我国粮价波动的影响因素很多,包括国际粮食市场环境、国家粮食政策、国内粮食产量、粮食生产和流通成本等.在粮食行业中,物流成本的“效益背反”存在于企业物流活动的方方面面,如物流成本与服务水平“效益背反”、物流各功能之间(运输、储存、包装、装卸等)“效益背反”、全社会物流资源“效益背反”.针对目前我国粮食物流成本占粮食销售价格比重过大且一直居高不下的情况,必须制订科学合理的方案,对我国粮食仓储节点布局和粮食物流过程进行优化,通过信息共享平台削弱粮食供应链中的“牛鞭效应”,整合资源降低“效益背反”对粮食物流成本的负面影响,积极推广第三方粮食物流外包,完善基础性建设,以稳定粮食市场价格波动.
