Therefore , it is not only important hut pressing to take such systematic measures as deepening the reform of scientific research system , emancipating the mind , perfecting the law of scientific research , formulating better environment of scientific research , optimizing research funds allocation and research teams , etc 因此，从深化科研体制改革，解放思想、完善科研立法、形成崇尚科学的良好环境，增大科研投入力度、优化科研资金投向，加强科学道德观念、优化科技队伍等多方面采取系统对策，对于提高我国科技创新能力有著十分重要的意义。
Consequently , in order to promote the application of water - saving irrigation technology . it is essential that ( 1 ) to strengthen farmers " participation in irrigation technology construction and management ; ( 2 ) to introduce credit means and scientific research of high technology and low cost ; ( 3 ) to carry out policy of adjustment of agricultural water price and product structure accordingly ; ( 4 ) to form system of water - saving irrigation technology according to water resource reserves and farmers " economical endurance in different areas 为此，提出以下促进中国农业节水灌溉技术应用的政策建议： ( 1 )加强灌溉工程建设和管理中的农户参与。 ( 2 )运用信贷手段和加强高科技含量、低成本的节水技术的科研投入等政府政府支持政策来激励农产的技术需求。 ( 3 )实行灌溉水价的结构性调整和农业生产结构调整相结合的策略，以便增强农户技术改造的积累能力； ( 4 )依据农业资源的地区性差异和农户的经济承受能力，分区域构建节水灌溉技术体系。
The growth of gdp , international cooperation revenue ( referring to the revenue from international contracting , labor service and design consulting , inte ) , foreign direct investment ( fdi ) , the share of employment of the tertiary industry ( ter ) , r & d investment by government ( rd ) are found to be the granger causes of cva growth , they driving construction industry ' s development in china . furthermore , gdp , the growth of inte , and fdi are cointegrated with cva and the growth of it , which means a certain trend is kept for a long time between any one of the first three time series and cva . however , cva is the granger - cause of the change of companies " structure , state - owned construction companies having less and less share in employees and output level among all kinds of enterprises 采用unitroottest和grangercausalitytest方法，对中国建筑业经济增长的相关变量进行granger因果分析，结果发现：中国gdp增长、对外经济合作(包括对外承包工程、劳务合作和设计咨询) 、外商直接投资、三次产业人员流动、国家科研投入都是建筑业产出增长的granger因，对建筑业成长有带动作用；其中， gdp 、对外经济合作和外商直接投资的增长分别与建筑业产业增加值增长有协整( cointegration )关系；建筑业产业成长则是其企业结构形态变动的granger因，国有企业在人员结构和产值结构中的比例都越来越小，产业的发展促使多种所有制形式的企业出现，提高市场竞争效率；文章还发现，在宏观经济政策方面，财政政策没有货币政策对中国建筑业的影响明显，虽然近年来积极的财政政策启动了不少大型基础设施项目，但由于“挤西安建筑科技大学博士论文出效应” ， granger检验显示政府的基建支出对建筑业增加值增长促进作用不显著;货币政策却由于对信贷和货币供给的控制而影响着建筑业的产出水平。
We should change the present situation ; priority should be given to a better understanding of the importance and necessity of educational research , and to a further comprehension of the unity of teaching and research . teachers " burden should be lightened and the school system needs to be adjusted and innovation encouraged so as to provide a good environment for productive research work and a viable means to improve its efficacy 我们应进一步提高教师对教育科研的必要性、重要性和与教学有机统一性的认识；减轻教师的教学工作负担；改革教育科研投入和管理体制；改革教育科研成果和职称评价制度；为教师努力营造一个宽松的科研环境，藉此来切实提高教师教育科研效能，发挥教育科研在中学教育中的应有作用。
