"Thirteenth Five -Year Plan"，my country's population development has occurred significant historic steering，The population and national conditions have also appeared new features that are completely different from the past，Highlighting the number of population in the development of the population、Structure、Quality、Distribution and other aspects of interweaving the new pattern。Based on the new national conditions，Showing a new responsibility for the long -term balanced development of population research to promote population research，Promote the new growth point of the population theoretical system with Chinese characteristics in the new era of active response to the aging of the population。Build a comprehensive system for the population research trend of economic and social development in the new era and the needs of national governance，New mission to become the academic community。

　Bet365 lotto review

Population is always the basic of national development、global、Long -term and strategic elements，Population scale、Structure、distribution、Quality and other elements are the most important national conditions in the economic and social development of the country。Overall，The main characteristics of the new national conditions in the new era include the following four aspects。

First，The population scale increases and decreases、New situation with slow growth。"Thirteenth Five -Year Plan" period is the peak period of the fertility policy adjustment，When the two children compensate for the accumulation of sexual fertility, the release is complete，The number of birth population gradually falls。Numerous women are reduced in scale、The long -term accumulation of fertility willingness to decline，"Fourteenth Five -Year Plan" period, although the population size of our country has maintained a growth trend，But the increase will Bet365 app download continue to reduce，Even a major turning point from growth to decline，Enter the negative population growth stage，The population scale shows a significant low -speed inertia growth feature in the whole。At the same time，With the decline in the direct intervention ability of the national fertility policy，Family internal constraints will gradually replace external control，Become a key factor affecting my country's future fertility level，The state will gradually turn to reducing the cost of raising、Reduce work conflict with family、Improve medical and health services and other measures to provide support for the family。

Second，The population structure is facing unprecedented new challenges。The adjustment of fertility policy during the "Thirteenth Five -Year Plan" period only brings a brief recovery of the birth population，But the long -term development trend has not changed。"Fourteen Five -Year Plan" period，The scale of the population born in my country、The size of the working age population will accelerate，Population dividends enter the downward channel。The scale of the elderly population、Family household size、The total support ratio will increase significantly，After 2020，my country will gradually enter a moderate aging society from an aging society，and expected to enter the super -aged society around 2035，Polo -child、aging、Empty nestization and aging problems coexist，I have put forward greater challenges to the social security and welfare system。At the same time，The marriage mentality of the wedding crowd gradually changed，Divorce rate、First marriage age、Cohabitation rate shows an upward trend，After superimposed with low fertility,，Caused a decline in the scale of the average family households，The number of household households will continue to grow，and the growth rate will be higher than the population growth rate，Available questions about empty nest families。

third，New difficulties for the improvement of population quality in economic transformation。With the rapid development of the economy and society，The positive effects of Bet365 app download national financial investment basic education and higher education have gradually appeared，my country's population quality and population quality continue to improve，It laid a certain human capital basis for economic and social development。But at this stage，The overall quality of our country is still significantly lower than the level of social development，Population quality improvement speed is also lagging behind the speed of economic development，Employees in low education level in the middle of low education levels are still high，The exacerbation of the number of population dividends disappears on the negative effects of the economy and society。How to improve population education and health quality in the future，to make up for the negative orientation of the downturn of the demographic dividend，It is a new issue that needs to be further resolved in population research and policy construction。

Fourth，New trends in regional imbalance of the population。Affected by my country's long -term socialist primary stage，my country's population continues to gather towards oversized cities，Population development presents significant regional differences，Urbanization development inequality、Unewal of population distribution and public resource allocation、Urban ecological deterioration and frequent urban diseases are still prominent。With the deepening of urbanization and the increase in the flow of flow，A single "population flow" incident gradually expanded to the group "flow population" problem，Population migration、Following the focus of the integration of flow and society into the focus of population research，and gradually deepen the left -behind children in the background of the large -scale population flow、Empty Nest Elderly, etc.。

　　A new mission of the Population Research

Compared with other discipline studies，Population research is more concerned about real problems，Emphasize from dynamics、Changes instead of quiet、Rigid perspective examines the new dynamics of the development situation of the population、New opportunities。So，Facing various problems in the Bet365 app download process of population transition，Population research should adhere to the road of population development suitable for China's national conditions，Research discourse system that keeps advancing with the times，Population governance ideas for the new era of population governance innovation and major population strategy change。

First，Reconstruction of the demographic discipline system and discourse system suitable for the new national conditions of China。my country as a modern post -developed country，Population problems are obviously different from Western countries，With unique laws of production and reproduction，and present a large scale、Transformation Fast、Complicated problems such as problems。At the same time，my country's population phenomenon and population problems also have a unique cultural and institutional background，Expressing strong practicality、Systematic and targeted，closely combined with the practice of local population policy in my country。

In order to better respond to the new needs of population development，Population research should re -examine the research and positioning of the new era，Reduce path dependence on Western theory，Innovation of the concept of governance and governance of population，Rooted in the law of population transformation and China National conditions，Based on China's research context，Spell academic propositions in the practice of local population，Form the theory of population transformation and governance with Chinese characteristics。Only deeply understand China's national conditions and deeply understand the law of population development,can we propose a localized theoretical discourse system that complies with the current stage of my country and the trend of economic and social development，To better promote population theory and method innovation。

Second，Cross -disciplinary integration for strengthening population research，Create new opportunities for development and development with interoperability。Population as the basic of economic and social development、Strategic、global、Long -term and key factors，The impact bet365 best casino games of the new steering of its development is not limited to the field of population，Instead, it is widely used in national economic and social stability、Multiple orientation of the quality of life of residents。So，my country's population research should be politics、Economy、Medical、Technical and other fields of different academic sciences cross -penetration、Organic combination，Adjust your own functional positioning，Cultivate researchers with the knowledge of population and other disciplines，Promote the construction of the comprehensive theoretical system，to better predict future governance risks，Turning crisis into a machine，Breeding new kinetic energy。

third，Give full play to the role of think tanks in the economic and social development of the population。Population Research as a direct decision reference and technical support for the top -level design，In the future, you need to explore more new ideas in the new situation of population development，Strengthen the overall thinking，Aware that the population problem is a complex system project，Focusing on the overall economic and social development，Through medium and long -term analysis and prediction，Better to the population test and challenge in the new period。At the same time，Due to the characteristics of Chinese population governance with diversity and complexity，Population research should also pay attention to the exploration of grassroots new ways to diversify population governance，Echo the macro design with the grass -roots population practice，Reduce policy split，The healthy interaction and organic connection of the construction of the top population system and the practice of grass -roots population governance，Effectively improve China's population research ability and level of governance，Better to the construction of a think tank to promote the modernization of the national governance system and governance capabilities in the new era，to effectively predict and prevent major social risk problems，Promoting Scientific Decisions for Population Problems，Policy -related policies for Bet365 app download high efficiency，Reasonably optimize the population decision -making mechanism and realize the implementation of scientific research results.。

Fourth，Promote the Innovation of Data Integration and Analysis Methods in the Context of Chinese Language。Population research emphasizes quantitative analysis and empirical research，Analysis method and technology innovation is important。Population analysis technology is using modern mathematics、Modern theory and research methods such as system engineering and electronic computers，Sort and analyze various population survey data，Therefore, the phenomenon of population and its economy、Culture and Society's connection The science of analysis and research。Facing the new problems and challenges of my country's population，Population research should not flow from pure theoretical perspective，should pay attention to the overall state of population operation and development、Constitutional conditions and governance mechanisms，Pay attention to the role of survey data，Improve the population survey method，Integrate the data of various departments，Building data open sharing platform，The ability to improve the use of research results to resolve future population contradictions and risks，Time、Innovative、Operations into principles，Application of improving population research，to actively adapt and actively respond to new problems in population development。other，It should also further innovate the technical method of population analysis，Use emerging technical means to sort out the population survey data，Explore the application of big data technology in population research，Realize the phenomenon of population and its economy、In -depth understanding of cultural and social connections。

In short，The population situation in my country is in an important period of turning in turns，The epidemic of new crown pneumonia is used as a sudden factor，It will also have fertility for people、Death、Migration and other impacts，Looking at it from the middle and long term，Contradictions of the population development of our country，The superposition Bet365 app download of a series of issues will have a profound impact on economic and social development。So，Based on the new national conditions，Grasp the new opportunity of the new growth point of population research to the development of disciplines，Adjusting the theoretical path and analysis method of adjusting population research，Especially from historical logic、Theoretical logic and practical logic interpretation should respond to the national strategy of aging population，To conform to the trend of population changes、Construction of relevant policies to adapt to the development situation、Realize forward -looking planning response，It has important significance。
