建筑企业如何开展人才管理

建筑企业实施人才管理十分重要，建筑企业是否成功，很重要的因素是企业经理是否具有丰富的领导才能，负责日常运营的企业管理是否具有高素质的“将才”，基层第一线生产是否成为冲锋陷阵的先锋。建筑企业必须切实制度好人才管理策略，建立健全人才储备库，善于控制人才，吸引高素质人才，并引入竞争机制，优胜劣汰。     

“营改增”影响地方政府税收努力研究

基于随机前沿分析法（SFA）测算2011-2015年我国地方政府税收努力程度,并运用双重差分法考察“营改增”对地方征税行为的影响。研究发现：“营改增”将地方税（营业税）变为共享税（增值税）,显著降低了地方政府税收努力程度;改革对税收努力的冲击受经济发展水平、转移支付额度和税收返还的影响,获取转移支付收入和税收返还越多的地区税收努力下降速度越快。后“营改增”时期,如何提高税收效率,缓解地方财政收入对转移支付和债务收入的依赖性,是理顺中央和地方财税关系,完善财税收入体系的重要问题。     

Carbon taxes and the double dividend hypothesis in a recursive-dynamic CGE model for Spain

A carbon tax is potentially a policy that can reduce CO₂ emissions and mitigate climate risks, at lowest economy-wide costs. We develop a dynamic CGE model for Spain to assess the economic and environmental effects of a carbon tax, and test the double dividend (DD) hypothesis. We simulate the impact of three carbon taxes: €10, €20 and €30 per ton of CO₂. For each tax, four ‘revenue recycling’ scenarios are examined: a reduction of taxes on capital, on labor, on value-added tax, and a scenario in which revenues are not recycled. We find a DD for taxes of €10/ton and lower, within five to seven years of implementation. We estimate an annual CO₂ emissions reduction of around 10% with this tax. Under some circumstances, the DD can be achieved for a tax of €20/ton. In any case, recycling revenues to cut pre-existing taxes reduces costs of imposing carbon taxes.     

双线螺纹带轮套的加工对车工高级人才培养的探析

双线螺纹加工方法较多,用数控机床加工相对简单,普通车床加工双线螺纹也比较普遍,这不仅可以锻炼机加工者的水平也是高级车工必备的技能,是一项难度大的加工工艺。以C6140型普通车床为加工设备,对带有双线螺纹带轮套的加工方法做一详细的分析,通过对双线螺纹带轮的加工分析,可以充分发挥此项加工项目在普通车工高级人才培养中的作用,对当今社会极需的高级车工人才培养具有一定的帮助。     

Oil risk contracts,business conduct and performance patterns: Data panel analysis

Using the economic and financial performance data of international companies for the exploration, and exploration–extraction (E&E) of oil, as well as the patterns of institutional situation and orientation with the government market and national oil companies or NOCs that receive project offers, we analyze the institutional development and behavior patterns by type of E&E contract, following the strategic actor approach, or the so-called agency theory. Additionally, in light of Mexico's energy reform being implemented between 2015 and 2019, we analyzed the types of license contracts compared to those for production and shared profit. Subsequently, it was determined-through panel data methods in the analysis of 17 companies between 2005 and 2015-that global companies present bigger yields and commitments compared to specialized companies, confirmed by their net income and returns on equity or ROE.     

反腐倡廉环境下创新国有企业领导人员经济责任审计内容探讨

反腐倡廉环境下创新国有企业领导人员经济责任审计内容是一项新的课题。本文对探索创新国有企业领导人员经济责任审计内容的必要性和我国法律规定的国有企业领导人员经济责任审计内容进行了综述，并根据审计实践，提出了“探索开展国有企业绩效审计”等5项审计内容，对创新国有企业领导人员经济责任审计内容进行了探讨，并针对目前创新国有企业领导人员经济责任审计内容面临的困难提出了健全绩效审计法律法规和评价指标、完善企业增资扩股行为的法律法规、加强对基层审计人员的培训学习等3条对策。     

因材施教——声乐教学的重要法则

声乐与其它的艺术形式存在着明显的区别，由于难以形象地对声乐的乐理、思想等进行表达，因此在声乐教学的过程中如何有效地让学生更好地理解声乐知识，更好地掌握发声技巧等一直是广大声乐教师关注的重点。鉴于此，文章主要就声乐教学中的因材施教进行研究，通过努力在声乐教学中推动因材施教，学生才能对此会产生更浓厚的兴趣，更好地用声乐来表达内心的思想与情感。     

客户协同创新维度及构成实证研究

客户协同创新是开放网络环境下企业创新能力提升的重要途径。基于协同理论、关系嵌入理论及客户参与创新等理论基础，对客户协同创新要素进行理论分析。采用探索性案例分析法，归纳客户协同创新要素特征，包括由互惠利益、关系质量和持续意愿构成的协同关系嵌入，由程序化协调、人际关系协调构成的协调协作机制，以及由信息资源分享、协同任务分担构成的协同资源投入。以案例研究结论为基础，进行量表开发，选择知识密集型服务业为实证对象，验证客户协同创新维度构成，可为客户协同创新机理研究与应用实践提供理论基础。     

Strong Nash equilibrium in games with common and complementary local utilities

A rather general class of strategic games is described where the coalitional improvements are acyclic and hence strong Nash equilibria exist: The players derive their utilities from the use of certain facilities; all players using a facility extract the same amount of local utility therefrom, which amount depends both on the set of users and on their actions, and is decreasing in the set of users; the ultimate utility of each player is the minimum of the local utilities at all relevant facilities. Two important subclasses are “games with structured utilities,” basic properties of which were discovered in 1970s and 1980s, and “bottleneck congestion games,” which attracted researchers’ attention quite recently. The former games are representative in the sense that every game from the whole class is isomorphic to one of them. The necessity of the minimum aggregation for the existence of strong Nash equilibria, actually, just Pareto optimal Nash equilibria, in all games of this type is established.     

The substitutes condition and the lattice structure of the set of stable allocations

In the many-to-one matching model with contracts, I show that there is no restriction on preferences weaker than substitutable preferences which guarantees that the set of stable allocations is a lattice. Thus, when contracts are not substitutes, removing agents from the economy may decrease the payoffs to existing agents on both sides of the market.
