The impact of license regulation on the number of recreation trips: is it worth considering?

A two-stage nonlinear least-squares model (2NLS) with an endogenous treatment effect on recreation trips describes the behavior of recreationists with and without a fishing/hunting license. The proposed 2NLS is applied to the derivation of the policy-relevant average gains in the presence of an endogeneity bias to a license fee implementation program regulated by states. Recreationists who purchased a license are likely to recreate more than are the nonlicensed holders because the regulation may reduce congestions at sites where licensee visit often. The license regulation has a greater impact on the use of natural resources after controlling observed and unobserved confounders which might be correlated with the probability of being a license holder and with the final outcome, the number of recreation trips. We confirm that the individual without a permit regards the recreation trip as less valuable than does the individual having a license permit. We also found that the likelihood of purchasing a license among young adult recreationists is not at the level the states may desire. In addition, the number of trips demanded is more responsive to the nontransportation-related implicit travel cost than to the transportation-related implicit travel cost, although travel implicit costs are price inelastic.      

行业协会有效性的品牌经济学研究

依据品牌经济学原理,对我国行业协会的发展现状进行分析,可发现,协会现行的会费收入追求尽可能多的会员数量,而监督的有效性又要求会员数量是有限的,因此,协会收入主要来源于会费的收取,是造成行业协会诸多问题的根本原因。将协会品牌引入行业协会的运营中,将协会的收入来源从以会费为主转到协会品牌内部和外部的授权收入的新的运营模式应成为我国行业协会的发展方向。     

“身份”特征差异对收入差距影响的经济学分析

根据雇佣要素的生产者均衡模型可得:准入管制下的非竞争性许可权收入份额远大于普通居民竞争性供给要素收入份额,如出租车行业约为6:4,而银行业管制租份额更高。主要机理是管制影响需求价格弹性,且更严格的管制降低了要素供给弹性,导致消费者支付高价、要素供给者不得不接受低价。     

关于注册会计师及会计师事务所特种执业资格管理问题的思考

在我国加入WTO及《行政许可法》即将实施的情况下，本文对我国目前注册会计师和会计师事务所从事证券期货相关业务采取特种执业许可证制度所存在的问题进行了多角度的分析，并提出了应当取消注册会计师及会计师事务所特种执业许可证制度，以及在取消特种许可证审批管理办法后应采取加强管理的措施。     

实行企业法人资格与经营资格分别登记管理制度的探讨

笔者认为我国现行的《企业法人营业执照》同时确认了企业法人资格和经营资格的登记管理制度是不科学的,在实践中已暴露出司法实践的不统一、不规范和行政管理上的矛盾与混乱等诸多弊端,需要对其改革,建立两套相对独立的管理体制,分别核发《企业法人执照》与《企业营业执照》,分别作为企业法人资格和经营资格的证明,并分别进行管理。     

车牌自动识别技术研究

本文提出的车牌识别技术,在定位环节根据图像清晰度的不同采用不同的边缘检测算子,通过"角点提取"获取候选区位置,通过"模糊外轮廓的汉字识别"进行汉字提取。实验结果表明,本研究对全天候图像的整体定位率大约为97.7%,字符识别率大约为95.6%,整个车牌识别系统的识别率约为93.4%,平均识别时间约为0.5s/幅,识别率有较大的提高。

Which Firms Buy Licenses? Market Positions and License Expenditures*

This paper presents the empirical results of a comparison of technology licensing expenditures of German companies in order to test implications of the Gilbert and Newbery (1982) model. Aside from standard control variables, the motives for innovation expenditures are also taken into account. We differentiate between firms intending to secure their present position in the market (incumbents) and those intending to enter a new market (challengers). In line with the prediction of the Gilbert and Newbery model, we find that incumbents show higher expenditures for technology licenses than potential entrants.     

中国跨省流动人口状况——基于“六普”数据的分析

利用2010年第六次全国人口普查数据,对不同省、市、自治区的跨省流动人口和分省户籍人口分布状况,以及分省迁入率和迁出率进行了估计。通过构造常住地-户籍地迁移矩阵,并计算相应的流出和流入人口在区域上的分布,通过对几个流入人口大省和流出人口大省的人口流入和流出状况进行分析,回答了他们是从哪来的,以及他们到哪里去了。同时对不同地区流动人口受教育状况,离开户籍所在地的时间也进行了描述。最后还对迁移率与收入的关系进行了分析。
