Activity Data and Emission Factor for Forestry and Other Land Use Change Subsector to Enhance Carbon Market Policy and Action in Malawi

Activity data and emission factors are critical for estimating greenhouse gas emissions and devising effective climate change mitigation strategies. This study developed the activity data and emission factor in the Forestry and Other Land Use Change (FOLU) subsector in Malawi. The results indicate that “forestland to cropland,” and “wetland to cropland,” were the major land use changes from the year 2000 to the year 2022. The forestland steadily declined at a rate of 13,591 ha (0.5%) per annum. Similarly, grassland declined at the rate of 1651 ha (0.5%) per annum. On the other hand, cropland, wetland, and settlements steadily increased at the rate of 8228 ha (0.14%);5257 ha (0.17%);and 1941 ha (8.1%) per annum, respectively. Furthermore, the results indicate that the “grassland to forestland” changes were higher than the “forestland to grassland” changes, suggesting that forest regrowth was occurring. On the emission factor, the results interestingly indicate that there was a significant increase in carbon sequestration in the FOLU subsector from the year 2011 to 2022. Carbon sequestration increased annually by 13.66 ± 0.17 tCO2 e/ha/yr (4.6%), with an uncertainty of 2.44%. Therefore, it can be concluded that there is potential for a Carbon market in Malawi.

Exchange Rate Change, Factor Market Distortion and Company Performance

Based on the matched data of China’s tax survey and customs from 2007 to 2011,this paper studies the differential impact of exchange rate changes on the performance of companies by region from the perspective of factor market distortion.The results show that for import companies,the RMB appreciation significantly contributes to improving their performance and this phenomenon is more pronounced in areas with high factor market distortions.Channel tests show that the proportion of intermediate goods imported by final producers increases with regional factor market distortions.Therefore,the appreciation of the national currency is more favorable for areas with high factor market distortions(companies with high proportion of imported intermediate goods).In addition,the appreciation of the national currency will promote the production of China’s upstream intermediate goods producers by expanding the output of downstream enterprises.This paper complements previous studies on the differential impact of RMB exchange rate changes on regional economic growth from a micro perspective.

Cassava sector development in Cameroon: Production and marketing factors affecting price

Regular and available supply is the prerequisite of an effective and efficient commercialization process. Using multivariate regression analysis on field data, this research appraises the production and marketing factors that influence cassava market price. The production factors include cultivated area, planting material, yield, and farmers’ field schools;while farmers access to a paved road, having a telephone, the transportation costs of fresh roots, the level of root perishability, and the prices of rice and maize stand as marketing factors. The results show that farmers who attended farmers’ field school adopted improved planting materials, propagated them in their localities and the yields in these communities increased significantly. The farm size also has a significant influence on the availability of fresh roots. On the marketing side, transportation costs, access to a paved road, the prices of rice and maize significantly affect cassava’s market price and tighten the relationship between producers and marketers. We conclude that to increase fresh roots supply, roads leading to cultivating areas should be paved, better transportation provided, communication costs reduced, even distribution of planting materials and appropriate warehouses.

Factor and Cluster Analysis as a Tool for Patient Segmentation Applied to Hospital Marketing in Jordan

Hospital marketing is becoming important for the survival and the prosperity of the health service. In addition, it indirectly acts as a formal feedback channel for the customer requirements, preferences, suggestions and complaints. In this work we have undertaken a survey based marketing study for two main objectives: The first being to better understand the patient clusters through k-means clustering and the second to understand customer perception of the different known quality perspectives through factor rotated and unrotated analysis. All of the questionnaires were designed according to international studies. Based on general descriptive statistics, items classified with higher variance but important, are: clean environment, doctors and nurses capabilities, and specialized doctors. Items that are less important with low variance are: food type, lighting and insurance. Also, items classified as more important with low variance are: recommended, no mistakes, and the cost. Using factor analysis rotated and unrotated reduced the variables into five main variables described as: medical aspects, psychological aspects, cost aspects, hospital image and ease of access and procedures. Using k-means clustering, the customers can be clustered into four main clusters with two of them described as general patient with wide variety of interest, serious cases interested in specialized doctors and food, and very serious case with high stress on equipment, no mistakes.

数字经济、要素市场化与产业结构转型升级

作为一类高融合性、高协同性、高成长性、高科技性的经济形态,数字经济为产业结构转型升级提供新动能。立足2009—2021年中国10个国家级城市群面板数据,借助双固定效应模型检验数字经济、要素市场化与产业结构升级之间的关系。结果显示:数字经济、要素市场化与政府治理转型均能推动产业结构转型升级,且要素市场化、政府治理转型在数字经济推动产业结构升级过程中发挥中介效应。不同数字经济类型对各城市群产业结构升级均具有正向推动作用,且在空间层面呈现“东部地区>中部地区>东北地区>西部地区”趋势。相比于大型城市,中小城市要素市场化对产业结构升级的促进作用更强,数字经济对产业结构升级的促进作用偏小。另外,产业数字化对产业结构转型升级的作用存在显著单一门槛效应,即跨过门槛值后产业数字化方可显著推动产业结构升级。据此,提出构筑数字经济发展新生态、布局要素市场化配置新机制、构建区域协同发展新格局的建议,为产业结构转型升级提供新思路。

反腐败斗争对推动共同富裕的正向作用——基于省际平衡面板数据(2005—2021)比较分析的实证研究

党的十八大以来,全面从严治党取得了历史性、开创性成就,反腐败斗争取得了压倒性胜利并得到了全面巩固,在此过程中,“反腐败影响经济增长”的论调“若隐若现”。以翔实数据论证反腐败斗争促进经济发展、推动共同富裕目标的事实成为当前极为重要的一个课题。本研究基于2005—2021年省际平衡面板数据,运用双重差分法探讨党的十八大之前和之后两时期反腐败斗争对推动共同富裕的影响。研究发现,进入新时代,反腐败斗争显著促进了共同富裕目标,反腐败斗争可通过促进非国有经济发展与整个要素市场发育而提高地区共同富裕水平。在稳健性分析中,通过安慰剂检验以解决不可观测到的因素对回归结果产生的影响,该结果依然成立。该研究结果价值主要体现在两方面:一者,能有力回应“反腐败影响经济增长”之荒谬论调;另者,能够丰富“反腐败”“共同富裕”等研究领域的相关文献。

土地政策松绑与县域新型城镇化——来自农村宅基地改革的经验证据

以县域为重要载体的新型城镇化是实现中国式现代化的必由之路,但随着农村剩余劳动力的不断外流,土地粗放利用、宅基地闲置甚至抛荒问题日益凸显。宅基地改革是促进土地要素与新型城镇化协调发展的重要举措,基于宅基地改革试点政策,运用多期双重差分法构造准自然实验,检验农村宅基地改革能否促进县域新型城镇化。研究发现:农村宅基地改革可以显著提升县域新型城镇化水平。政策路径识别发现,农村宅基地改革从非农就业、产业结构升级和激发市场潜能三方面提升县域新型城镇化水平。异质性研究表明,行政区划上,农村宅基地制度改革对于县、县级市和市辖区的新型城镇化水平提升能力呈现递增趋势;地区差异上,农村宅基地制度改革的政策效应在东部、中部地区县域得到有效发挥,对西部地区县域新型城镇化水平提升效果有限。通过土地政策改革推进以县域为载体的新型城镇化提供了经验证据,同时也从经验上就如何稳慎推进农村宅基地改革试点提供政策启示。

市场性因素介入之内幕交易罪违法所得的计算

内幕交易罪等证券类犯罪因涉及多方主体、复杂的违法链条、严重的危害后果以及隐蔽的犯罪手段,对市场交易秩序造成严重破坏,一直是监管部门严厉打击的重点。为实现刑法的有效规制并保障人权,科学准确地计算内幕交易罪的违法所得数额显得尤为重要。在实践中,市场性因素的介入会导致内幕交易罪中行为人所获得的收益或避免的损失数额增大。对于扩大的收益或者避免的损失数额,由于不符合没收违法所得制度的宗旨与内涵,因此不能计入行为人的违法所得数额。在具体计算方法上,法院可以综合选取相关市场指数或者个股组合作为参照,综合测算市场性因素所导致的股市波动权重,进而将其从违法所得的认定中排除。

A Fast LDL-factorization Approach for Large Sparse Positive Definite System and Its Application to One-to-one Marketing Optimization Computation

LDL-factorization is an efficient way of solving Ax = b for a large symmetric positive definite sparse matrix A. This paper presents a new method that further improves the efficiency of LDL-factorization. It is based on the theory of elimination trees for the factorization factor. It breaks the computations involved in LDL-factorization down into two stages： 1） the pattern of nonzero entries of the factor is predicted, and 2） the numerical values of the nonzero entries of the factor are computed. The factor is stored using the form of an elimination tree so as to reduce memory usage and avoid unnecessary numerical operations. The calculation results for some typical numerical examples demonstrate that this method provides a significantly higher calculation efficiency for the one-to-one marketing optimization algorithm.

碳排放权交易、数字经济与企业全要素生产率

“双碳”战略目标的提出契合高质量发展的内在需要,碳排放权交易市场是实现该目标的关键工具,2013—2014年,我国建立了首批七个试点碳交易市场,近十年以来,此项政策的减排效果已经受到广泛认可,但其对经济发展的影响依然值得探究。基于2010—2019年重污染行业A股上市公司的数据,本文以首批七个试点碳交易市场的正式启动为准自然实验,构建双重差分模型探讨该项政策对企业全要素生产率的影响,并从碳交易市场特征和数字经济发展的角度对作用机制进行分析。研究发现,碳交易政策能够显著提高企业的全要素生产率。机制分析表明,在碳交易政策对全要素生产率的作用过程中,企业数字化转型发挥了部分中介作用。此外,碳交易政策效果在非国有企业、风险承担水平高的企业中更强,并且碳市场的交易规模、流动性、数字基础设施、互联网普及率和数字普惠金融的发展都对碳交易政策效果发挥着正向调节效应,碳配额价格水平也具有一定的负向调节效应。
