共享平台在构建和完善自身生态品牌时,通过与相关企业或其他平台合作共同创造生态价值,这一模式被称为“共享+”模式。本文首先考虑平台价值独创情形,分析该情形下的最优策略。接着,本文进一步考虑平台作为主创者和多个共创者之间的微分博弈,并在该情形下决策最优努力水平的Nash均衡。最后,本文考虑平台根据共创者努力水平给予激励的Stackelberg主从博弈。本文在分析平台价值独创策略、价值共创策略和共创激励策略时发现,共创激励策略下平台的价值产量和最优收益均最高,且该策略下平台付出的努力最少;其次为无激励的价值共创策略,而价值独创策略表现最差。创造者的最优收益和价值产量在三种策略下均关于时间单调递增,但增速越来越慢,最后趋于收敛值。参数弹性分析表明,共创者的变现能力和价值产出率正向影响均衡解,而边际成本、价值自然损失率、折扣因子均负面影响均衡解。本文结论解释了抖音、拼多多等平台的补贴机制,印证了价值共创是平台和共创者的双赢策略。

大气压低温等离子体可以利用空气直接进行氧化固氮,具有反应条件温和、参数灵活可控、避免温室气体排放等优点.本文利用双针-板电极在水中形成气泡放电等离子体,以空气为放电气体进行了固氮研究,分析了产物浓度和固氮能耗的影响因素.研究结果表明,等离子体中含有丰富的氮原子、氧原子、氢原子、激发态氮分子等活性物种,可高效合成硝态含氮产物.研究发现,脉冲参数、电极间隙、工作气体组分对气泡放电等离子体的固氮性能有重要影响.装置最高NO~-_x合成速率为19.2μmol/min,最小能耗约为11 MJ/mol.此外还发现,电极间隙为6 mm时,固氮性能最优;空气中增加适量氧气(氧气/氮气比例为0.4)可以增强产物合成,降低能耗.

随着社会经济的发展和人口结构的深刻调整,中国女性劳动参与率发生了显著变化。改革开放初期,中国女性劳动参与率显著高于欧美主要发达国家的水平,但近年来大幅下降,已接近其平均值。研究发现,已生育女性劳动参与率的下降是整体趋势的主要驱动力,而婚育模式的转变在一定程度上对这一趋势起到了缓冲作用。对于已婚女性而言,学龄前子女的照料负担逐渐成为劳动市场参与的核心制约因素。女性教育水平的提升通过禀赋和系数效应显著促进了劳动参与,但配偶教育水平的影响由正向转为负向,说明家庭收入能力的提高减弱了女性劳动参与的经济动机,强化了性别分工的传统趋势。优化育儿支持体系、促进性别平等以及营造职场友好环境,是缓解婚育负担对女性劳动市场参与约束的关键政策方向。

Double carbohelicenes have attracted considerable attention due to their aesthetic structures, distinct π-conjugation extension, inherent chirality, and intriguing optical and electronic properties. Herein, the concise de novo synthesis of a new double[5]carbohelicene 1 together with its chiroptical properties, isomerization process and lasing application is presented. 1 was synthesized by a simple protocol involving the formation of a 6,6′-bipentacene as the key intermediate. It is worth noting that1 existed as two diastereomers 1-PP/MM and 1-PM, which were successfully isolated and unambiguously confirmed by Xray crystallography. The optical resolution of the racemic 1-PP/MM was successfully achieved by chiral-phase highperformance liquid chromatography（HPLC）, and 1-PP and 1-MM were characterized by circular dichroism. Interestingly, it was found that 1-PP/MM could be completely isomerized to 1-PM upon heating, and the detailed thermodynamics and kinetics of the isomerization process were systematically investigated. 1-PM exhibited deep-red luminescence with emission maximum at 723 nm and fluorescence quantum yield as high as 32.95%. Consequently, we can showcase the lasing application of 1-PM by doping with epoxy resin to assemble a bottle microlaser spontaneously, which the lasing wavelength is 796.6 nm at a threshold of 0.8 m J cm-2. We believe that our studies, including the facile synthesis methodology, detailed isomerization studies, and lasing application, will shed some light on the design and synthesis of novel carbohelical systems with more functions.
