Research on the Investment Mode and Path of China’s Construction Waste Resourceization Industry

At present,China’s construction waste accounts for about 40%of the total municipal solid waste,with a large stock,a large increment,and a low rate of resource utilization,which is still a big gap compared with developed countries.However,the market prospect of the construction waste industry is relatively broad,the reuse value of the construction waste is high,so these resources should be fully utilized.This paper presents an in-depth analysis of projects in the construction waste resourceization industry,examining the industrial chain,development history,current status,investment and financing modes,and case studies.It proposes targeted strategies for companies to focus on the upstream and downstream segments of the construction industry’s value chain and explores the implementation of investment opportunities in construction waste resourceization.

Cost Control Strategies in the Pre-Construction Period of Highway Construction

Effective cost control in the investment and design phases of highway construction is crucial for managing project expenses.However,current management practices often overlook pre-construction cost management,leading to budget overruns and project delays during later stages.To ensure the smooth execution and cost control of highway construction projects,this paper examines the significance of cost control,evaluates the current state and challenges of highway construction,and proposes strategies for cost management.These strategies aim to establish a robust foundation for cost management in highway projects.

Multi-Criteria Decision-Making for Power Grid Construction Project Investment Ranking Based on the Prospect Theory Improved by Rewarding Good and Punishing Bad Linear Transformation

Using the improved prospect theory with the linear transformations of rewarding good and punishing bad(RGPBIT),a new investment ranking model for power grid construction projects(PGCPs)is proposed.Given the uncertainty of each index value under the market environment,fuzzy numbers are used to describe qualitative indicators and interval numbers are used to describe quantitative ones.Taking into account decision-maker’s subjective risk attitudes,a multi-criteria decision-making(MCDM)method based on improved prospect theory is proposed.First,the[−1,1]RGPBIT operator is proposed to normalize the original data,to obtain the best andworst schemes of PGCPs.Furthermore,the correlation coefficients between interval/fuzzy numbers and the best/worst schemes are defined and introduced to the prospect theory to improve its value function and loss function,and the positive and negative prospect value matrices of the project are obtained.Then,the optimization model with the maximum comprehensive prospect value is constructed,the optimal attribute weight is determined,and the PGCPs are ranked accordingly.Taking four PGCPs of the IEEERTS-79 node system as examples,an illustration of the feasibility and effectiveness of the proposed method is provided.

Current Situations and Problems of Investment in Agricultural Capital Construction from the Perspective of Investment of Different Ministries and Commissions and Recommendations

Investment in agricultural capital construction is an important factor in improving China's agricultural productivity and international competitiveness. In recent years,the attention to the investment in agricultural capital construction has been lifted to a strategic height. However,there is still little research on the investment in agricultural capital construction. From the perspective of investment of different ministries and commissions,this paper systematically analyzed current situations,problems,and came up with recommendations for the investment in the agricultural capital construction. According to the results,( i) from 1983 to the present,China's investment in agricultural capital construction experienced three stages. Especially after 2010,the scale of investment in agricultural capital construction was huge,and it showed a rapid increasing trend;( ii) the investment in agricultural capital construction is characterized by " multi-sector investment,different departments having different investment priorities and investment scale in different periods";( iii) some investment projects are overlapping between departments,local areas are weak in providing support funds,project construction standard is single,and there are problems of attaching importance to the application,belittling the management,stressing the construction,belittling the maintenance,and serious brain drain;( iv) different departments have accumulated certain experience in long-term exploration. For example,they pay more attention to the refinement and differentiation of projects,focus on the development of targeted poverty alleviation,pay more attention to the " quality" of investment,and pay more attention to the transformation of agricultural production methods. Based on current situations and problems,it came up with recommendations including promoting the integration of funds for investment and project integration,strengthening the personnel cultivation,ensuring simultaneous construction and management of projects,stressing the maintenance after project construction,exploring new modes for project design,management,investment,and financing,and enhancing the support for special investment projects.

The Impact of State Policies on Investment Project Management in Polish Industrial Construction Sector

In this paper,we discuss the influence of economic,environmental and legal policies of the state on the management of investment projects in the area of industrial construction in Poland.Our empirical study relies on conducting a questionnaire survey.A total of 158 Polish companies dealing with industrial construction took part in the survey.Then,the collected questionnaires were subjected to a thorough analysis and interpretation,with the use of a method called the exploratory factor analysis(EFA).Our research reveals the key factors influencing successful investment project management in the Polish industrial construction sector.These factors have been identified as the“availability of technology in a stable political system”,“stability of the economic and tax systems”,“stable social system policy,stability and transparency of the legal system”and a“well-targeted environmental policy”.A key conclusion that can be drawn from our study is that an efficient management of investment projects in the industrial construction industry is significantly influenced by properly shaped and stable economic,environmental,and legal policies of the state.

私募投资基金涉罪的争点问题思考

私募投资基金行业在快速发展的过程中,不仅暴露了不少违规经营、管理失范等问题,而且涉及相关刑事犯罪。私募投资基金涉罪,包括纯正的私募基金犯罪和不纯正的私募基金犯罪两类。从非法性要素看,私募机构未经登记备案而擅自募集基金有可能涉嫌非法集资,但也不能仅仅因为行为违反了私募基金管理有关规定就直接认定为构成非法集资犯罪,要构成非法集资犯罪必须同时违反关于非法集资的相关法律规定。从金融性要素看,“私募基金管理公司”不属于有关《刑法》条文规定中的“基金管理公司”范围。从募集性要素看,私募基金管理人采用代持、拼单或非法拆分等间接投资方式募集基金,突破合格投资者限制,涉嫌变相非法集资。私募基金涉罪的监管规制路径包括完善有关刑事立法、司法解释规定,重视企业合规管理。

数字基础设施建设如何影响民营企业投资效率——营商环境的中介效应

为探究数字基础设施建设对中国民营企业投资效率的影响,并考察营商环境在其中的中介作用。基于2013-2022年中国30个省级行政区和上市民营企业的面板数据,采用双向固定效应模型与中介效应模型进行经验分析。研究结果显示,数字基础设施建设显著提升了上市民营企业的投资效率,并有效缓解了企业投资不足与投资过度的问题。营商环境的中介效应检验结果表明,数字基础设施建设优化了营商环境,通过聚集人才和吸引投入促进了民营企业投资效率的提升。异质性分析显示,改善的数字基础设施在经济发达的东部地区对解决民营企业的投资过度和不足问题更为显著,而在经济发展相对落后的中西部地区,其改善主要集中于解决企业的投资不足问题。综上所述,针对民营企业投资疲软的现实困境,应当加快数字基础设施投资与建设,释放数字红利,并进一步发挥数字基础设施建设对营商环境的改善作用,以助力民营企业实现投资效率的提升与高质量发展。

基于地方债置换视角的城投债风险化解研究

从地方债认购倍数、各省地方债与城投债发行利差、境外资金对城投债与地方债的持有量变化等角度,分析境内外资金对券种的投资偏好差异,初步测算各省可行性地方债置换规模并提出城投化债方案。研究发现:(1)本轮化债之前,各省地方债发行利率均低于该省AAA级城投债发行利率,并且发生过城投风险事件省份的利差更大;化债之后,利差有收窄趋势;(2)投资者对某省地方债的偏好高于该省城投债,并且境内资金对发生城投风险事件省份地方债的偏好更加明显;(3)按照2022年财政收入和地方债余额测算,除吉林和云南外,其余省份地方债发行规模尚未触及阈值,存在地方债置换空间。基于上述实证结论,提出城投债化解的政策建议。

基于InVEST模型的黔中喀斯特地区建设用地扩张碳储量变化研究

选择典型生态脆弱区黔中典型喀斯特地区—普定县为研究对象,采用土地利用动态度和土地利用转移分析方法,应用InVEST模型测算2003-2020年的陆地生态系统碳储量及其空间分布格局,探讨建设用地扩张对碳储量变化的影响。结果表明:(1)2003-2020年建设用地面积一直保持增加趋势,扩张速率表现为减缓态势,空间变化在中南部区域最为显著,主要侵占旱地、水田和灌木林地。(2)普定县碳储量整体呈上升趋势,累计增加15.07×10^(5)t,主要因碳密度较高的灌木林地大幅挤占旱地。(3)建设用地变化致使碳储量损失了22.37×10^(4)t,以中南部中心城区碳储量下降最为明显。因此,建议研究区在城市扩张过程中优先考虑碳密度较低的未利用地,同时限制建设用地对旱地、水田以及灌木林地的占用,以减少建设用地扩张对区域碳储存能力的影响。

河南省水利建设资金投入实证分析与预测研究

水利建设投资是重要的基础性投资,对促进经济社会发展具有重要作用。采用实证分析法、以“十二五”“十三五”(2011—2020年)期间为时间序列,依据河南省水利建设投资数据,利用对比分析法、相关性分析法、投入产出法、贡献率分析法等,分析河南省2011—2020年水利建设投资的变化特征和趋势、水利建设投资与经济社会发展之间的相互关系、水利建设与经济发展产出效益的关系、水利建设投入对经济社会发展的贡献率等。结果表明:水利建设投入额与经济社会发展情况高度相关,但水利建设投入额在时间序列上表现出的不稳定性扰动水利行业自身发展的同时,也对经济社会发展产生不利影响;将研究结果数据作为基础数据,采用GM预测模型和ARIMA预测模型拟合预测得到“十四五”期间河南省水利建设投资总规模为2 838.95亿元,水利建设投资对GDP平均贡献率为0.41%,对财政收入平均贡献率为3.70%。同时,对河南省下一阶段水利建设投资优化提出了建议。
