After discussing the tariff taxation policy ' s aim , tep theory and tep ' s operating mechanism , the second paragraph establishes the index system to evaluate the effect of tep , which is the foundation of the whole paper . the index system includes foreign investments , industry , import and export , tariff revenues , trade relations and so on 论文第二部分:在前文对关税有效保护政策目标、关税有效保护理论、关税有效保护作用机制三者进行分析的基础上,本部分建立了一套评价关税有效保护效果的指标体系,这套指标体系包括“有效保护率( erp ) 、外商投资、产业、进出口、关税收入、调整对外经贸关系”六个方面的内容。
The appropriate town development direction of dahe were the east , the northeast . choosing economic development , population and resource limit as factors , the possibility - satisfaction model for town land scale decision was established . the dahe town land scale in 2010 would be 338 ha 以经济水平、人口规模、资源条件为影响因素,国内生产总值、土地经济产出、人均用地指标、土地可供应量、耕地保护率为影响因子,构建了大河镇城镇用地规模的“可能一满意度”决策模型,通过模型运行,确定了大河镇2010年城镇用地总规模为338公顷。
Abstract : tongbai county of henan province is one of the high - epidemic areas of bovine theileriosis . in 1985 , gelatin - protected schizont cell vaccine for 20 , 000 cattle was introduced . from ningxia institute of animal husbandry and veterinary medicine against theileria annulata . on the basis of regional tests , the vaccine was applied throughout 16 townships of the county . the annual investigation showed that the safety of the vaccine was 100 % . among the 15 , 000 cattle ( including 4 , 500 water buffaloes ) inoculated with the vaccine , only 3 cattle suffered from theileriosis . the incident rate was 0 . 02 % . however of the 3600 un - inoculated cattle , 2060 heads suffered from the disease . the incident rate was 5 . 7 % . the effective protection reached 99 . 98 % with a significant social and economic effect 文摘:河南省桐柏县是牛环形泰勒虫病流行的多发区,对养牛业危害十分严重, 1985年该县从宁夏农林科学院畜牧兽医研究所引进“虫苗” 2万头份,在区域试验的基础上在全县16个乡(镇)进行了大面积防疫注射,经年终统计表明:虫苗安全性100 % ,注苗15000头(其中有水牛4500头) ,发病3头,发病率0 . 02 % ;未注苗36000头,发病2060头,发病率5 . 7 % ,实际有效保护率达99 . 98 % ,取得了明显的社会经济效益。
Foreign investment , industry , import and export . it deems that the biggest shortcoming of tep is not that tax level ' s decrease shocks import and export markets , but that the ratio - grads - structure is irrationality , which results in insufficiency of protection to key parts and semi - finished products . it is just the bottleneck of the whole industry 主要是从关税有效保护率、外商投资、产业、进出口四方面在于关税下调导致进口剧增冲击了国内市场,而在于产业的关税梯度结构不合理、对关键资本投入品的保护不足、技术进步缓慢从而成为整个产业发展的瓶颈。
Yherefore , many researchers have shown great concern with the development of vaccines to against schistosomiasis . at early stage , the research of vaccines of schitosomiasis was centered on dead vaccine and athenuated cercaria of schistosomes while molecular vaccine and athenuated cercaria of schistosomes while molecular vaccine is currently the focus of research with anti - infection protective immunity as its main concern . guan xiaohong and zhao weixian ( 1986 ) certified that the allergen of egg granulonma of schistosoma japonicum might firstly come from gut associated antigen ( gaa ) of schistosomula and adult worm and that daa had cross reaction with soluble egg antigen ( sea ) and membrane associated antigen ( maa ) ; and the gaa of schistosoma japonicum might play a sensitizing role in egg granuloma formation Np30主动免疫c57bl 6对尾蚴攻击感染产生42 . 05的保护力,肝组织减卵率为66 . 63 ; balb c和昆明种小鼠的保护率分别为39 . 53和50 . 46 ;免疫山羊可诱导42 . 78的减虫率,肝组织减卵率为35 . 83 ,粪减卵率为25 ,并可明显抑制肝脏虫卵肉芽肿的大小,肉芽肿数量明显减少,纤维化减轻,体重明显增加,因此np30是南京医科大学博士学位论文很有希望的抗日本血吸虫病疫苗侯选分子。
Through forming a framework of domestic rate of cost , the thesis has analyzed the competitive advantages from three levels , resource allocation efficiency of fresh fruits , latent competitive advantages and protective level and distorting degree from the government firstly . then , the thesis post - analyzed and examined the comparative advantages of china ' s apple and orange with tsc and kca . it consider that apple , orange , pear in china gave higher competitive advantages but the competitive advantage of fruits is decreasing in general , mandarin orange and golden orange ' s export competitiveness is stronger while aurantium , lemon and bitter orange have no export competitiveness at all 本文通过建立国内资源成本分析框架,应用国内资源成本分析法( drc ) 、社会效益分析法( nsp ) 、有效保护率法( erp ) ,从几种鲜果生产的资源配置效率,潜在的比较优势和政策保护水平以及扭曲程度3个层面对中国苹果和柑橘的比较优势进行了事前分析;然后运用净出口指标(贸易专门化系数, tsc )分析法, “显性比较优势系数” ( rca )分析法对中国苹果和柑橘的比较优势进行事后分析和检验。
