Corporate strategy adjustments caused by natural bet365 free bets depletion、Regional industrial transformation and social harmony and stability，It is a "Trinity" system engineering，Also management、Economics、Interdisciplinary research field of sociology and political science。Over the years，Governments at all levels have issued a series of fiscal policies、Financial policy and industrial policy，Related companies formulate strategies、Adjust layout，Strive to escape the "bet365 free bets curse"。Overall, it seems to be very effective，The price is not small；Lots of experience，Lots of lessons learned。

From the perspective of economic development and resource endowment，The general trend in our country is to develop the eastern part early，Resources tend to be exhausted；Late development of the western region，Relatively abundant resources。How to smoothly transfer resource-exhausted enterprises in the east to the central and western regions，How to scientifically evaluate the effect of this cross-regional transfer，Become an important research topic。"Inter-regional bet365 free bets resource-exhausted enterprises and its spillover and coercion effects" (Li Cunfang et al.，Science Press December 2021 Edition) 155 projects based on the cross-regional transfer of resource-exhausted enterprises in eastern my country from 1992 to 2020 and their implementation status，Systematic study of the development process and exit characteristics of resource-depleted enterprises。There are three important concepts or performance indicators proposed and used in the book: "spillover effect", "coercion effect" and "ecological spillover efficiency"。Used as a formula, it is "ecological spillover efficiency of the transfer of resource-depleted enterprises = spillover effect/coercion effect"，The author mainly uses these three indicators to conduct in-depth research。

First，From the perspective of the coupling of advantageous elements in resource-rich areas in the east and central and western regions，Exploring the scientific nature of cross-regional bet365 free bets enterprises。Supplies with production capacity in the east，There is also a "demand" for resources；There is a "supply" of resources in the Midwest，There is also a “quest” for economic development，This coupling or equilibrium of supply and demand，It is the inherent requirement of market economy to allocate resources，It is also the general trend of my country’s economic development at this stage。

This book passes system analysis，Reveals that eastern resource-exhausted enterprises face serious resource depletion and sustainable development problems due to long-term development，Have key technologies at the same time、Efficient management、Excellent talents、Adequate funds and other advantages。The existing industrial concentration of resource development in the central and western regions is relatively low、There is a lot of waste in resource development、Safety and new geological disaster hazards are greater、Development disadvantages such as serious damage to the ecological environment，Also has some advantages，Such as rich resources、Preferential policies、Surplus manpower、Smooth logistics, etc.。Both parties have obvious complementary characteristics and coupling conditions，Once the coupling is successfully completed，To achieve a win-win situation。The author discovered through analysis，The degree of coupling of this system，It not only reflects the mutual influence between resource-depleted enterprises in the east and resource-rich areas in the central and western regions、The degree of synergy，And the intensity of corporate bet365 free bets，And it can be used as a scientific basis for enterprises to choose the destination for cross-regional transfer。

Secondly，Systematic research on positive spillover effects and negative coercion effects from the cross-regional bet365 free bets resource-depleted enterprises in the east，Revealing the regularity of cross-regional bet365 free bets enterprises。Realization of cross-regional bet365 free bets resource-exhausted enterprises in eastern China，Not only the process of cross-regional investment，It must also be accompanied by key technologies、Transfer of knowledge such as efficient management。This transfer behavior may produce positive spillover effects，Promote the improvement of total factor productivity and operational efficiency of undertaking enterprises and high-quality economic and social development，The formation involves issues of economic system and social system。As a transfer of resource development activities，The transfer of enterprises across regions will also produce a certain degree of negative coercive effects such as land destruction and environmental pollution。Therefore，Need to be included in an economic subsystem、In the composite system of social subsystem and environmental subsystem，Positive spillover effects from the cross-regional transfer of resource-exhausted enterprises in the east、In-depth research on negative coercion effects。

Author’s research findings，The cross-regional bet365 free bets eastern resource-exhausted enterprises has intra-industry spillover effects，There are also inter-industry spillover effects。Intra-industry spillover effects are mainly generated through demonstration and imitation channels and competition optimization channels，And the spillover efficiency of competition optimization channels is significantly higher than the spillover efficiency of demonstration and imitation channels。The inter-industry spillover effect mainly results from its participation in the industrial division of labor in resource-rich areas in the central and western regions，Embedded in local industrial chain，Form new changes in technology and management based on input-output correlation，Promote local inter-industry related enterprises to improve technology and management，Improve management level、Product quality and total factor productivity。It’s just that the intensity of the spillover effect between industries is lower than the intensity of the spillover effect within the industry，The main reason is that the resource industry is relatively specialized，Industrial correlation is relatively weak。At the same time，Inter-regional bet365 free bets resource-exhausted enterprises in the east，The coercion effect is also caused by the interaction between the coercion strengthening flow and the coercion weakening flow。The intensity of this coercion effect shows an "inverted U-shaped" trend，And affected by some specific factors。

　Finally，Orientation from the perspective of ecological spillover efficiency evaluation，Study and judge the effectiveness of corporate cross-regional transfer control policies。Inter-regional bet365 free bets resource-exhausted enterprises in the east，If the spillover effect is significant，For the resource industry in resource-rich areas in the central and western regions，Even the improvement of total factor productivity in related industries、Structural optimization、High-quality development has a promoting effect；If the coercion effect is significant，The damage or threat to the ecological environment of resource-rich areas in the central and western regions will be intensified，The construction of ecological civilization will be inhibited。

The author proposed a new concept of "ecological spillover efficiency" for cross-regional bet365 free bets enterprises。In 1992, the "World Business Council for Sustainable Development" (WBCSD) proposed the concept of "eco-efficiency"，To explain the ratio relationship between economic output and environmental impact，That is, the economic output obtained by the economy in exchange for unit environmental damage。The "ecological spillover efficiency" is the ratio between the spillover output of the transfer behavior and the environmental impact，That is, the external economic output obtained by the economy in exchange for unit environmental damage。This book uses DEA data envelopment analysis method and Malmquist exponential model，Select relevant data of the resource industry in ten provinces and regions in the central and western regions for ten years to conduct empirical testing and find out，“Ecological spillover efficiency” can not only scientifically measure the ratio of spillover effects and coercion effects of enterprises’ cross-regional transfer behavior，Enrich organizational behavior、Theoretical system of resource economy and enterprise strategic management，And it can clearly reflect the environmental damage caused by corporate cross-regional transfer projects，The size of the economic contribution to the industry other than the transferred project and even related industries。

Based on the current new development stage、Implement new development concepts、In the context of building a new development pattern，This book focuses on the major practical issues of effective exit and sustainable development of resource-exhausted enterprises in my country，The system explains why resource-exhausted enterprises move、Can it be transferred、How to bet365 free bets、Where to turn、What is the effect、Magnitude of effect、Basic theoretical issues such as how to regulate。Looking forward to the author taking this as a new starting point，Further attention to new hot and difficult issues emerging in the practice of high-quality development of my country's resource-based industries and the construction of ecological civilization，Insist on originality、Unity of ideology and science，Insist on telling the story of China’s economic management in academic language，Use your team’s strengths，Cross integration，Breakthrough the bottleneck，Make more contributions to constructing and enriching economic management theory and policy research。
