System Change of Collective Forest Tenure Oriented to Deepening the Reform

We firstly introduce development background of new collective forest tenure reform.The situations indicate that the collective forest tenure reform has already stepped into comprehensive and in-depth stage.However,due to neglect of local demands and actual conditions,there appear problems of low operating efficiency of supporting measures and relevant policies and little effect of in-depth reform.Therefore,it is required to strictly distinguish the relation between system change of collective forest tenure and the in-depth reform.For the purpose of in-depth reform,in accordance with local situations of forest farmers and forestry organizations,requirements for system,as well as local reform conditions,we strictly divide system change of collective forest tenure into three types:induced institutional change,hidden induced institutional change and imposed institutional change.Then,we divide the imposed institutional change into weak institutional change and pure strong institutional change.

Ecological Hidden Troubles and Countermeasures under Reform of Collective Forest Tenure

Three stages of reform of collective forest tenure after reform and opening up are reviewed.The reform of forest tenure brings sharp increase of economic benefit.However,due to forest farmers' subjective pursuit for economic benefit and objective lack of necessary economic,financial and technical support,ecological hidden troubles are created.Based on these,we put forward countermeasures,including strengthening forest farmers' awareness of ecological protection and solving ecological problems in accordance with actual conditions of the region.

Forest Tenure and Sustainable Forest Management

We reviewed the principles and key literature related to forest tenure and sustainable forest management, and then examined the status of sustainable forestry and land ownership at the aggregate national level for major forested countries. The institutional design principles suggested by Ostrom are well accepted for applications to public, communal, and private lands. The analyses of countries as a whole suggest that problems of forest land loss and sustainable forest management are related to the amount of public lands owned, as well as the difference between developed and developing countries. Developed countries have largely achieved a stable level of land use and resource extraction after centuries of exploitation of forests and natural resources. Many developed countries do have greater amounts of private forest land than developing countries, which have occurred as the countries transfer lands to private owners in the course of development. Public lands and management approaches require diligence, but can be developed to meet the design criteria suggested by tenure rights theorists. Private or communal ownership is often considered superior, but also must meet the criteria suggested above in order to foster sustainable forest management in poor countries.

Land tenure security,place satisfaction and loyalty in the peri-urban area of Ibadan City,Nigeria

Land tenure security is pertinent to achieving the sustainable development agenda in cities where land is needed and useful for development purposes.Sufficient empirical research has been done to prove the importance of tenure security for investment,resilience,conservation,food security,as well as health and well-being,but it has not been clarified if and how land tenure security could adequately influence place loyalty and satisfaction with the residential environment,as it is clear that place loyalty and satisfaction are pertinent to inclusive development.Using the case of Ibadan City,the study examined how different dimensions of tenure security could determine residents’place loyalty and satisfaction.The study employed a survey cross-sectional research design to distribute 514 structured questionnaires to household heads across 4 sampled peri-urban local government areas while 452 were retrieved for analysis.Hierarchical regression analysis model was employed to understand the association between tenure security dimensions and satisfaction(as model I)and loyalty(as model II).For model I,F=8.640,P=0.000,R=0.555,and R^(2)=0.308 were obtained;while for model II,F=9.157,P=0.001,R=0.415,and R^(2)=0.173 were acquired.This thus means that residents’place loyalty and satisfaction can partly be explained by tenure security.In particular,respondents with no eviction experience,recognized property rights,and invulnerable to eviction have higher odds of being satisfied and loyal.Therefore,we recommend protection,improvement,and upgrading of land tenure security as one of the means to promote place loyalty and satisfaction,which is essential to achieving inclusive and sustainable development.

隐性契约——董事长和总经理老乡关系如何影响公司创新?

老乡关系普遍存在于中国上市公司高管团队内部,通过影响人际交往中的互动原则,以一种非正式契约形式作用于公司战略决策,但对其影响机制研究仅停留在基于信任和规范角度的理论探索和推理层面。基于社会交换理论和关系交换理论,以董事长—总经理老乡关系为切入点,探讨董事长与总经理老乡关系对公司创新的影响。研究发现:董事长—总经理老乡关系正向影响公司创新;任期重叠作为一种内部资本,在董事长—总经理老乡关系对公司创新的影响中起中介作用;环境不确定性负向调节董事长—总经理老乡关系对公司创新的影响。研究剖析了中国独特的“同乡抱团”文化现象背后的公司治理效应,提出的董事长和总经理老乡关系影响公司创新的理论模型,是对非正式关系影响机理研究与创新前因研究的有益补充,也为公司利益相关者各方洞悉我国独特的“关系型社会”制度背景对公司治理的规制作用提供新的实证依据。

CEO任期、薪酬激励与企业双元创新

双元创新是企业可持续发展的重要途径,CEO任期对企业双元创新会产生何种影响尚未得到统一结论。以我国2017—2022年沪深A股上市公司为样本,运用固定效应模型探究CEO任期与企业双元创新之间的关系。研究结果显示:CEO任期对探索式创新产生负向影响,对开发式创新产生正向影响;薪酬激励在CEO任期与开发式创新之间起到显著正向调节作用,在CEO任期与探索式创新之间的正向调节作用不显著;CEO任期通过降低企业风险承担水平抑制探索式创新,通过缓解融资约束促进企业开发式创新;CEO任期与双元创新之间的关系在国有企业中更为明显。这些研究结论在丰富双元创新领域文献的同时,对企业科学完善CEO聘任制度和激励制度具有一定的启示意义。

基于k-means的动态多组织PBFT算法

联盟区块链系统被广泛用于金融和物流等场景。现有应用于区块链系统的实用拜占庭算法(practical Byzantine fault tolerance,PBFT)存在可扩展性较低及通信成本较高等问题,阻碍了区块链系统在大规模场景中的应用。针对上述问题,提出了一种动态多组织实用拜占庭容错算法(k-means-practical Byzantine fault tolerance,k-PBFT)。通过改进k-means算法,根据节点的时延以及节点间通信距离将节点分为多个自治组织,各组织之间通过组织代表节点进行通信。当新节点加入时,根据其特点将其分配到最合理的组织。同时,引入信誉机制以辨别系统中的诚实节点与恶意节点,从而提高系统的安全性。此外,该算法还引入节点任期机制,使区块链中每个诚实节点都有机会充当组织代表节点或主节点。实验结果表明,与PBFT算法相比,k-PBFT算法通信复杂度降低了75%;当节点数为100时,相比于PBFT算法,时延降低了210 ms,吞吐量提高了100%。在高延迟环境下,相较于基于信誉分组的PBFT改进算法,当节点数为100时,时延降低了20%,吞吐量提高了17%。
