The synergistic development of manufacturing and digital economy brings about the improvement of industrial operation efficiency and the transformation of production methods,which is an important driver of the high-quality development of manufacturing industry.Based on this,the article use the vertical and horizontal scatter degree method to measure the level of high-quality development of manufacturing and digital economy in 30 Chinese provinces from 2011 to 2020,and combine the coupling coordination degree model,Barrier Degree Model,Dagum Gini coefficient and Moran index to measure the coupling coordination degree of digital economy and high-quality development of manufacturing and analysis the regional differences,sources and spatial effects.The research shows that:(1)The coupling coordination degree of digital economy and high-quality development of manufacturing in China shows an upward trend from 2011 to 2020,but the coupling coordination levels are mainly barely coordination and primary coordination,and presents an uneven spatial pattern of"high in the east and low in the west"and"higher in the coast than inland".(2)The main factors restricting the coupling coordination of various provinces include the penetration rate of the Internet,the number of mobile Internet users,as well as the openness to foreign investment and the contribution to innovation.(3)The Dagum Gini coefficient shows that the overall differences of coupling coordination degree between manufacturing high-quality development and digital economy show a downward trend,mainly from the inter-regional difference.(4)Moran index shows that the coupling coordination degree of digital economy and high-quality development of manufacturing has a significant spatial correlation and agglomeration effect.
在早期的《1844年经济学哲学手稿》中,劳动产品的异化、劳动过程的异化、类本质的异化、人与人的异化构成马克思异化劳动理论的基本内容,它们既有区别又有联系,既不能混淆也不可偏废.人的(劳动)本质的丧失,乃是异化劳动的核心和实质所在.与此不同,在其成熟时期的《德意志意识形态》和《资本论》及其手稿中,马克思虽然保留和沿用了异化概念,但它不再意味着使人不成其为人的"非人"状态,而恰恰是对现实中处于特定际遇中的具体的人的描述;它也不再是本质地揭示社会存在和历史发展的理论基础和前提,而是对社会演化和历史运动之特定结果的表层把握.现实的人不是"人",而"人"却不是现实的,这是异化劳动理论难以摆脱的理论困境.把异化劳动分解为劳动异化和生命异化的所谓生存论式解读值得商榷.

Glabrous rice is an important germplasm resource with the characteristics of glabrousness,lodging resistance and good grain quality.The milling quality,appearance quality and cooking quality of the non-glabrous dual purpose male sterile line Y58S and four glabrous dual purpose male sterile lines derived from Y58S were analyzed and evaluated.Meanwhile,30 hybrid combinations were made from the above mentioned five male sterile lines as the female parent and six restorer lines according to the incomplete diallel cross design,and their grain quality traits were analyzed when they were planted as single-cropping late rice and double-cropping late rice,respectively.The results showed that the grain quality of 8CS963 and X8S010 reached the Ministry's standard of Grade 3.The combined results of two cropping seasons in grain quality revealed that,since the ratio of length to width of four glabrous sterile lines was significantly higher than that of Y58S(the control),most of their hybrid combinations had a higher ratio of length to width than the control group.Except for the hybrid combinations of X8S010/R028,X8S010/X9H003,8CS963/X9H003 and 7CS102/X9H003,which had a significantly higher head rice rate than that of the control group,the head rice rate of the other combinations was not better than that of the control group.The amylose content of the combinations of the glabrous sterile line X6S1791 was significantly higher than that of the other combinations in both cropping seasons.X8S010/X9H005 and Y58S/H070 reached the the Ministry's standard of Grade 3 when planted as single-cropping late rice.Y58S/H070 reached the Ministry's standard of Grade 2,and eight combinations including X8S010/X9H003 and 7CS102/X9H001 reached the Ministry's standard of Grade 3 when planted as double-cropping late rice.The other combinations failed to reach the quality standard mainly due to low alkali spreading value.The average variation values of chalky grain rate and chalkiness degree of the glabrous hybrid rice combinations between two cropping seasons were smaller than those of non-glabrous hybrid rice combinations,but the alkali spreading value was opposite,indicating that the chalky grain rate and chalkiness degree of glabrous hybrid rice combinations were less affected by temperature,but the alkali spreading value was more affected by temperature than that of non-glabrous hybrid rice combinations.
The development of dual-purpose male sterile lines and the registration and application of two-line hybrid rice varieties in China during 1973-2021 were analyzed.The results showed that by 2021,509 dual-purpose male sterile lines had been developed nationwide,and a number of two-line hybrid rice combinations had been developed and approved for commercial production by the national or provincial crop variety appraisal committees,the number of registered varieties increased from 28 during the Ninth Five-year Plan period to 1 550 during the 13th Five-year Plan period.The number of two-line super rice varieties identified by the Ministry of Agriculture and Rural Affairs is 31,which is slightly lower than that of the three-line super rice varieties,but in terms of the planting area per variety,the two-line hybrid rice is obviously higher than that of the three-line hybrid rice.
